# xxhash
|
||||
|
||||
[](https://pkg.go.dev/github.com/cespare/xxhash/v2)
|
||||
[](https://github.com/cespare/xxhash/actions/workflows/test.yml)
|
||||
|
||||
xxhash is a Go implementation of the 64-bit
|
||||
[xxHash](http://cyan4973.github.io/xxHash/) algorithm, XXH64. This is a
|
||||
high-quality hashing algorithm that is much faster than anything in the Go
|
||||
standard library.
|
||||
|
||||
This package provides a straightforward API:
|
||||
|
||||
```
|
||||
func Sum64(b []byte) uint64
|
||||
func Sum64String(s string) uint64
|
||||
type Digest struct{ ... }
|
||||
func New() *Digest
|
||||
```
|
||||
|
||||
The `Digest` type implements hash.Hash64. Its key methods are:
|
||||
|
||||
```
|
||||
func (*Digest) Write([]byte) (int, error)
|
||||
func (*Digest) WriteString(string) (int, error)
|
||||
func (*Digest) Sum64() uint64
|
||||
```
|
||||
|
||||
This implementation provides a fast pure-Go implementation and an even faster
|
||||
assembly implementation for amd64.
|
||||
|
||||
## Compatibility
|
||||
|
||||
This package is in a module and the latest code is in version 2 of the module.
|
||||
You need a version of Go with at least "minimal module compatibility" to use
|
||||
github.com/cespare/xxhash/v2:
|
||||
|
||||
* 1.9.7+ for Go 1.9
|
||||
* 1.10.3+ for Go 1.10
|
||||
* Go 1.11 or later
|
||||
|
||||
I recommend using the latest release of Go.
|
||||
|
||||
## Benchmarks
|
||||
|
||||
Here are some quick benchmarks comparing the pure-Go and assembly
|
||||
implementations of Sum64.

|
||||
These numbers were generated on Ubuntu 18.04 with an Intel i7-8700K CPU using
|
||||
the following commands under Go 1.11.2:
|
||||
|
||||
```
|
||||
$ go test -tags purego -benchtime 10s -bench '/xxhash,direct,bytes'
|
||||
$ go test -benchtime 10s -bench '/xxhash,direct,bytes'

|
||||
source, and configuration files.
|
||||
|
||||
"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but
|
||||
not limited to compiled object code, generated documentation,
|
||||
and conversions to other media types.
|
||||
|
||||
"Work" shall mean the work of authorship, whether in Source or
|
||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the
|
||||
Licensor for the purpose of discussing and improving the Work, but
|
||||
excluding communication that is conspicuously marked or otherwise
|
||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||

exercising permissions granted by this License.
|
||||

|
||||

|
||||
|
||||
"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but
|
||||
not limited to compiled object code, generated documentation,

|
||||
|
||||
"Work" shall mean the work of authorship, whether in Source or
|
||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the
|

excluding communication that is conspicuously marked or otherwise
|
||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
APPENDIX: How to apply the Apache License to your work.
|
||||
|
||||

// The stock metrics provided by this package (Gauge, Counter, Summary,
|
||||
// Histogram, Untyped) are also Collectors (which only ever collect one metric,
|
||||
// namely itself). An implementer of Collector may, however, collect multiple
|
||||
// metrics in a coordinated fashion and/or create metrics on the fly. Examples
|
||||
// for collectors already implemented in this library are the metric vectors
|
||||
// (i.e. collection of multiple instances of the same Metric but with different
|
||||
// label values) like GaugeVec or SummaryVec, and the ExpvarCollector.

// the last descriptor has been sent. The sent descriptors fulfill the
|
||||
// consistency and uniqueness requirements described in the Desc
|
||||
// documentation.
|
||||
//
|
||||
// It is valid if one and the same Collector sends duplicate
|
||||
// descriptors. Those duplicates are simply ignored. However, two
|
||||
// different Collectors must not send duplicate descriptors.
|
||||
//
|
||||
// Sending no descriptor at all marks the Collector as “unchecked”,
|
||||
// i.e. no checks will be performed at registration time, and the
|
||||
// Collector may yield any Metric it sees fit in its Collect method.
|
||||
//
|
||||
// This method idempotently sends the same descriptors throughout the
|
||||
// lifetime of the Collector. It may be called concurrently and
|
||||
// therefore must be implemented in a concurrency safe way.
|
||||
//
|
||||
// If a Collector encounters an error while executing this method, it

||||
// must send an invalid descriptor (created with NewInvalidDesc) to
|
||||
// signal the error to the registry.

||||
// descriptor of each sent metric is one of those returned by Describe
|
||||
// (unless the Collector is unchecked, see above). Returned metrics that
|
||||
// share the same descriptor must differ in their variable label
|
||||
// values.
|
||||
//
|
||||
// This method may be called concurrently and must therefore be
|
||||
// implemented in a concurrency safe way. Blocking occurs at the expense
|

// of total performance of rendering all registered metrics. Ideally,

// Collector implementations support concurrent readers.

// their descriptors to the provided channel.
|

//
|
||||
// If a Collector collects the same metrics throughout its lifetime, its
|
||||
// Describe method can simply be implemented as:

// the lifetime of the Collector in a way that their combined set of descriptors
|

||||
// of the Describe method. If a Collector sometimes collects no metrics at all
|
||||
// (for example vectors like CounterVec, GaugeVec, etc., which only collect
|
||||
// metrics after a metric with a fully specified label set has been accessed),
|
||||
// it might even get registered as an unchecked Collector (cf. the Register
|
||||
// method of the Registerer interface). Hence, only use this shortcut
|

// implementation of Describe if you are certain to fulfill the contract.

// Package prometheus is the core instrumentation package. It provides metrics
|

// primitives to instrument code for monitoring. It also offers a registry for

// metrics. Sub-packages allow to expose the registered metrics via HTTP
|

// (package promhttp) or push them to a Pushgateway (package push). There is

//
|

|
||||
//
|
||||
// package main
|
||||
//
|
||||
// import (
|
||||
// "log"
|
||||
// "net/http"
|
||||
//
|
||||
// "github.com/prometheus/client_golang/prometheus"
|
||||
// "github.com/prometheus/client_golang/prometheus/promhttp"
|

// )
|
||||
//

||||
// var (
|
||||
// cpuTemp = prometheus.NewGauge(prometheus.GaugeOpts{
|
||||
// Name: "cpu_temperature_celsius",
|
||||
// Help: "Current temperature of the CPU.",
|
||||
// })
|
||||
// hdFailures = prometheus.NewCounterVec(
|
||||
// prometheus.CounterOpts{
|
||||
// Name: "hd_errors_total",
|
||||
// Help: "Number of hard-disk errors.",
|
||||
// },
|
||||
// []string{"device"},
|
||||
// )
|
||||
// )
|
||||
//
|
||||
// func init() {
|
||||
// // Metrics have to be registered to be exposed:
|
||||
// prometheus.MustRegister(cpuTemp)
|
||||
// prometheus.MustRegister(hdFailures)
|
||||
// }
|
||||
//
|
||||
// func main() {
|
||||
// cpuTemp.Set(65.3)
|
||||
// hdFailures.With(prometheus.Labels{"device":"/dev/sda"}).Inc()
|
||||
//
|
||||
// // The Handler function provides a default handler to expose metrics
|
||||
// // via an HTTP server. "/metrics" is the usual endpoint for that.
|
||||
// http.Handle("/metrics", promhttp.Handler())
|
||||
// log.Fatal(http.ListenAndServe(":8080", nil))
|
||||
// }
|
||||
//
|
||||
//
|
||||
// This is a complete program that exports two metrics, a Gauge and a Counter,
|
||||
// the latter with a label attached to turn it into a (one-dimensional) vector.
|
||||
//
|
||||
// Metrics
|
||||
//
|
||||
// The number of exported identifiers in this package might appear a bit
|
||||
// overwhelming. However, in addition to the basic plumbing shown in the example
|
||||
// above, you only need to understand the different metric types and their
|
||||
// vector versions for basic usage. Furthermore, if you are not concerned with
|
||||
// fine-grained control of when and how to register metrics with the registry,
|
||||
// have a look at the promauto package, which will effectively allow you to
|
||||
// ignore registration altogether in simple cases.
|
||||
//
|
||||
// Above, you have already touched the Counter and the Gauge. There are two more
|
||||
// advanced metric types: the Summary and Histogram. A more thorough description
|
||||
// of those four metric types can be found in the Prometheus docs:
|
||||
// https://prometheus.io/docs/concepts/metric_types/
|
||||
//
|
||||
// In addition to the fundamental metric types Gauge, Counter, Summary, and
|
||||
// Histogram, a very important part of the Prometheus data model is the
|
||||
// partitioning of samples along dimensions called labels, which results in
|
||||
// metric vectors. The fundamental types are GaugeVec, CounterVec, SummaryVec,
|
||||
// and HistogramVec.
|
||||
//
|
||||
// While only the fundamental metric types implement the Metric interface, both
|
||||
// the metrics and their vector versions implement the Collector interface. A
|
||||
// Collector manages the collection of a number of Metrics, but for convenience,
|
||||
// a Metric can also “collect itself”. Note that Gauge, Counter, Summary, and
|
||||
// Histogram are interfaces themselves while GaugeVec, CounterVec, SummaryVec,
|
||||
// and HistogramVec are not.
|
||||
//
|
||||
// To create instances of Metrics and their vector versions, you need a suitable
|
||||
// …Opts struct, i.e. GaugeOpts, CounterOpts, SummaryOpts, or HistogramOpts.
|
||||
//
|
||||
// Custom Collectors and constant Metrics
|
||||
//
|
||||
// While you could create your own implementations of Metric, most likely you
|
||||
// will only ever implement the Collector interface on your own. At a first
|
||||
// glance, a custom Collector seems handy to bundle Metrics for common
|
||||
// registration (with the prime example of the different metric vectors above,
|
||||
// which bundle all the metrics of the same name but with different labels).
|
||||
//
|
||||
// There is a more involved use case, too: If you already have metrics
|
||||
// available, created outside of the Prometheus context, you don't need the
|
||||
// interface of the various Metric types. You essentially want to mirror the
|
||||
// existing numbers into Prometheus Metrics during collection. An own
|
||||
// implementation of the Collector interface is perfect for that. You can create
|
||||
// Metric instances “on the fly” using NewConstMetric, NewConstHistogram, and
|
||||
// NewConstSummary (and their respective Must… versions). NewConstMetric is used
|
||||
// for all metric types with just a float64 as their value: Counter, Gauge, and
|
||||
// a special “type” called Untyped. Use the latter if you are not sure if the
|
||||
// mirrored metric is a Counter or a Gauge. Creation of the Metric instance
|
||||
// happens in the Collect method. The Describe method has to return separate
|
||||
// Desc instances, representative of the “throw-away” metrics to be created
|
||||
// later. NewDesc comes in handy to create those Desc instances. Alternatively,
|
||||
// you could return no Desc at all, which will mark the Collector “unchecked”.
|
||||
// No checks are performed at registration time, but metric consistency will
|
||||
// still be ensured at scrape time, i.e. any inconsistencies will lead to scrape
|
||||
// errors. Thus, with unchecked Collectors, the responsibility to not collect
|
||||
// metrics that lead to inconsistencies in the total scrape result lies with the
|
||||
// implementer of the Collector. While this is not a desirable state, it is
|
||||
// sometimes necessary. The typical use case is a situation where the exact
|
||||
// metrics to be returned by a Collector cannot be predicted at registration
|
||||
// time, but the implementer has sufficient knowledge of the whole system to
|
||||
// guarantee metric consistency.
|
||||
//
|
||||
// The Collector example illustrates the use case. You can also look at the
|
||||
// source code of the processCollector (mirroring process metrics), the
|
||||
// goCollector (mirroring Go metrics), or the expvarCollector (mirroring expvar
|
||||
// metrics) as examples that are used in this package itself.
|
||||
//
|
||||
// If you just need to call a function to get a single float value to collect as
|
||||
// a metric, GaugeFunc, CounterFunc, or UntypedFunc might be interesting
|
||||
// shortcuts.
|
||||
//
|
||||
// Advanced Uses of the Registry
|
||||
//
|
||||
// While MustRegister is the by far most common way of registering a Collector,
|
||||
// sometimes you might want to handle the errors the registration might cause.
|
||||
// As suggested by the name, MustRegister panics if an error occurs. With the
|
||||
// Register function, the error is returned and can be handled.
|
||||
//
|
||||
// An error is returned if the registered Collector is incompatible or
|
||||
// inconsistent with already registered metrics. The registry aims for
|
||||
// consistency of the collected metrics according to the Prometheus data model.
|
||||
// Inconsistencies are ideally detected at registration time, not at collect
|
||||
// time. The former will usually be detected at start-up time of a program,
|
||||
// while the latter will only happen at scrape time, possibly not even on the
|
||||
// first scrape if the inconsistency only becomes relevant later. That is the
|
||||
// main reason why a Collector and a Metric have to describe themselves to the
|
||||
// registry.
|
||||
//
|
||||
// So far, everything we did operated on the so-called default registry, as it
|
||||
// can be found in the global DefaultRegisterer variable. With NewRegistry, you
|
||||
// can create a custom registry, or you can even implement the Registerer or
|
||||
// Gatherer interfaces yourself. The methods Register and Unregister work in the
|
||||
// same way on a custom registry as the global functions Register and Unregister
|
||||
// on the default registry.
|
||||
//
|
||||
// There are a number of uses for custom registries: You can use registries with
|
||||
// special properties, see NewPedanticRegistry. You can avoid global state, as
|
||||
// it is imposed by the DefaultRegisterer. You can use multiple registries at
|
||||
// the same time to expose different metrics in different ways. You can use
|
||||
// separate registries for testing purposes.
|
||||
//
|
||||
// Also note that the DefaultRegisterer comes registered with a Collector for Go
|
||||
// runtime metrics (via NewGoCollector) and a Collector for process metrics (via
|
||||
// NewProcessCollector). With a custom registry, you are in control and decide
|
||||
// yourself about the Collectors to register.
|
||||
//
|
||||
// HTTP Exposition
|
||||
//
|
||||
// The Registry implements the Gatherer interface. The caller of the Gather
|
||||
// method can then expose the gathered metrics in some way. Usually, the metrics
|
||||
// are served via HTTP on the /metrics endpoint. That's happening in the example
|
||||
// above. The tools to expose metrics via HTTP are in the promhttp sub-package.
|
||||
//
|
||||
// Pushing to the Pushgateway
|
||||
//
|
||||
// Function for pushing to the Pushgateway can be found in the push sub-package.
|
||||
//
|
||||
// Graphite Bridge
|
||||
//
|
||||
// Functions and examples to push metrics from a Gatherer to Graphite can be
|
||||
// found in the graphite sub-package.
|
||||
//
|
||||
// Other Means of Exposition
|
||||
//
|
||||
// More ways of exposing metrics can easily be added by following the approaches
|
||||
// of the existing implementations.

// Package promauto provides alternative constructors for the fundamental
|
||||
// Prometheus metric types and their …Vec and …Func variants. The difference to
|
||||
// their counterparts in the prometheus package is that the promauto
|
||||
// constructors return Collectors that are already registered with a
|
||||
// registry. There are two sets of constructors. The constructors in the first
|
||||
// set are top-level functions, while the constructors in the other set are
|
||||
// methods of the Factory type. The top-level function return Collectors
|
||||
// registered with the global registry (prometheus.DefaultRegisterer), while the
|
||||
// methods return Collectors registered with the registry the Factory was
|
||||
// constructed with. All constructors panic if the registration fails.

//
|
||||
// This appears very handy. So why are these constructors locked away in a
|
||||
// separate package?
|
||||
//
|
||||
// The main problem is that registration may fail, e.g. if a metric inconsistent
|
||||
// with or equal to the newly to be registered one is already registered.
|
||||
// Therefore, the Register method in the prometheus.Registerer interface returns
|
||||
// an error, and the same is the case for the top-level prometheus.Register
|
||||
// function that registers with the global registry. The prometheus package also
|
||||
// provides MustRegister versions for both. They panic if the registration
|
||||
// fails, and they clearly call this out by using the Must… idiom. Panicking is
|
||||
// problematic in this case because it doesn't just happen on input provided by
|
||||
// the caller that is invalid on its own. Things are a bit more subtle here:
|
||||
// Metric creation and registration tend to be spread widely over the
|
||||
// codebase. It can easily happen that an incompatible metric is added to an
|
||||
// unrelated part of the code, and suddenly code that used to work perfectly
|
||||
// fine starts to panic (provided that the registration of the newly added
|
||||
// metric happens before the registration of the previously existing
|
||||
// metric). This may come as an even bigger surprise with the global registry,
|
||||
// where simply importing another package can trigger a panic (if the newly
|
||||
// imported package registers metrics in its init function). At least, in the
|
||||
// prometheus package, creation of metrics and other collectors is separate from
|
||||
// registration. You first create the metric, and then you decide explicitly if
|
||||
// you want to register it with a local or the global registry, and if you want
|
||||
// to handle the error or risk a panic. With the constructors in the promauto
|
||||
// package, registration is automatic, and if it fails, it will always
|
||||
// panic. Furthermore, the constructors will often be called in the var section
|
||||
// of a file, which means that panicking will happen as a side effect of merely
|
||||
// importing a package.
|
||||
//
|
||||
// A separate package allows conservative users to entirely ignore it. And
|
||||
// whoever wants to use it, will do so explicitly, with an opportunity to read
|
||||
// this warning.
|

//

// Package promhttp provides tooling around HTTP servers and clients.

//
|

// First, the package allows the creation of http.Handler instances to expose

// Prometheus metrics via HTTP. promhttp.Handler acts on the
|
||||
// prometheus.DefaultGatherer. With HandlerFor, you can create a handler for a
|
||||
// custom registry or anything that implements the Gatherer interface. It also
|
||||
// allows the creation of handlers that act differently on errors or allow to
|
||||
// log errors.
|
||||
//
|
||||
// Second, the package provides tooling to instrument instances of http.Handler
|
||||
// via middleware. Middleware wrappers follow the naming scheme
|
||||
// InstrumentHandlerX, where X describes the intended use of the middleware.
|
||||
// See each function's doc comment for specific details.
|
||||
//
|
||||
// Finally, the package allows for an http.RoundTripper to be instrumented via
|
||||
// middleware. Middleware wrappers follow the naming scheme
|
||||
// InstrumentRoundTripperX, where X describes the intended use of the
|
||||
// middleware. See each function's doc comment for specific details.

|
||||
|
||||
1. Definitions.
|
||||
|

|
||||
direction or management of such entity, whether by contract or
|
||||
otherwise, or (ii) ownership of fifty percent (50%) or more of the

"You" (or "Your") shall mean an individual or Legal Entity
|
||||
exercising permissions granted by this License.
|
||||
|
||||
"Source" form shall mean the preferred form for making modifications,
|
||||
including but not limited to software source code, documentation
|
||||
source, and configuration files.
|
||||
|
||||
"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but
|
||||
not limited to compiled object code, generated documentation,
|
||||
and conversions to other media types.
|
||||
|
||||
"Work" shall mean the work of authorship, whether in Source or
|
||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the
|
||||
Licensor for the purpose of discussing and improving the Work, but
|
||||
excluding communication that is conspicuously marked or otherwise
|
||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||

|
||||
|
||||
1. Definitions.
|
||||
|
||||
"License" shall mean the terms and conditions for use, reproduction,
|
||||
and distribution as defined by Sections 1 through 9 of this document.
|
||||
|
||||
"Licensor" shall mean the copyright owner or entity authorized by

||||
the copyright owner that is granting the License.
|
||||
|
||||
"Legal Entity" shall mean the union of the acting entity and all
|
||||
other entities that control, are controlled by, or are under common
|
||||
control with that entity. For the purposes of this definition,
|
||||
"control" means (i) the power, direct or indirect, to cause the
|
||||
direction or management of such entity, whether by contract or
|
||||
otherwise, or (ii) ownership of fifty percent (50%) or more of the
|
||||
outstanding shares, or (iii) beneficial ownership of such entity.
|
||||
|
||||
"You" (or "Your") shall mean an individual or Legal Entity
|
||||
exercising permissions granted by this License.
|
||||
|
||||
"Source" form shall mean the preferred form for making modifications,

|
||||
source, and configuration files.
|
||||
|
||||
"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but
|
||||
not limited to compiled object code, generated documentation,
|
||||
and conversions to other media types.
|
||||
|
||||
"Work" shall mean the work of authorship, whether in Source or
|
||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the
|
||||
Licensor for the purpose of discussing and improving the Work, but
|
||||
excluding communication that is conspicuously marked or otherwise
|
||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||

||||

|
||||
// line, info type, stateset type, gaugehistogram type.
|

//
|

// exemplars that are larger than allowed by the OpenMetrics specification).
