THIS WILL INVALIDATE ALL + PERSISTED FINGERPRINTS. IF YOU COMPILE THE PROMETHEUS SERVER WITH THIS + VERSION, YOU HAVE TO WIPE THE PREVIOUSLY CREATED STORAGE. +* [CHANGE] LabelValuesToSignature removed. (Nobody had used it, and it was + arguably broken.) +* [CHANGE] Vendored dependencies. Those are only used by the Makefile. If + client_golang is used as a library, the vendoring will stay out of your way. +* [BUGFIX] Remove a weakness in the fingerprinting for metrics. (This made + the fingerprinting change above necessary.) +* [FEATURE] Added new fingerprinting functions SignatureForLabels and + SignatureWithoutLabels to be used by the Prometheus server. These functions + require fewer allocations than the ones currently used by the server. + +## 0.2.0 / 2015-02-23 +* [FEATURE] Introduce new Histagram metric type. +* [CHANGE] Ignore process collector errors for now (better error handling + pending). +* [CHANGE] Use clear error interface for process pidFn. +* [BUGFIX] Fix Go download links for several archs and OSes. +* [ENHANCEMENT] Massively improve Gauge and Counter performance. +* [ENHANCEMENT] Catch illegal label names for summaries in histograms. +* [ENHANCEMENT] Reduce allocations during fingerprinting. +* [ENHANCEMENT] Remove cgo dependency. procfs package will only be included if + both cgo is available and the build is for an OS with procfs. +* [CLEANUP] Clean up code style issues. +* [CLEANUP] Mark slow test as such and exclude them from travis. +* [CLEANUP] Update protobuf library package name. +* [CLEANUP] Updated vendoring of beorn7/perks. + +## 0.1.0 / 2015-02-02 +* [CLEANUP] Introduced semantic versioning and changelog.

It has two separate parts, one for +instrumenting application code, and one for creating clients that talk to the +Prometheus HTTP API. + +__This library requires Go1.7 or later.__ + +## Important note about releases, versioning, tagging, and stability + +While our goal is to follow [Semantic Versioning](https://semver.org/), this +repository is still pre-1.0.0. To quote the +[Semantic Versioning spec](https://semver.org/#spec-item-4): “Anything may +change at any time. The public API should not be considered stable.” We know +that this is at odds with the widespread use of this library. However, just +declaring something 1.0.0 doesn't make it 1.0.0. Instead, we are working +towards a 1.0.0 release that actually deserves its major version number. + +Having said that, we aim for always keeping the tip of master in a workable +state. We occasionally tag versions and track their changes in CHANGELOG.md, +but this happens mostly to keep dependency management tools happy and to give +people a handle they can talk about easily. In particular, all commits in the +master branch have passed the same testing and reviewing. There is no QA +process in place that would render tagged commits more stable or better tested +than others. + +There is a plan behind the current (pre-1.0.0) versioning, though: + +- v0.9 is the “production release”, currently tracked in the master + branch. “Patch” releases will usually be just bug fixes, indeed, but + important new features that do not require invasive code changes might also + be included in those. We do not plan any breaking changes from one v0.9.x + release to any later v0.9.y release, but nothing is guaranteed. Since the + master branch will eventually be switched over to track the upcoming v0.10 + (see below), we recommend to tell your dependency management tool of choice + to use the latest v0.9.x release, at least for your production software. In + that way, you should get bug fixes and non-invasive, low-risk new features + without the need to change anything on your part. +- v0.10 is a planned release that will have a _lot_ of breaking changes + (despite being only a “minor” release in the Semantic Versioning terminology, + but as said, pre-1.0.0 means nothing is guaranteed). Essentially, we have + been piling up feature requests that require breaking changes for a while, + and they are all collected in the + [v0.10 milestone](https://github.com/prometheus/client_golang/milestone/2). + Since there will be so many breaking changes, the development for v0.10 is + currently not happening in the master branch, but in the + [dev-0.10 branch](https://github.com/prometheus/client_golang/tree/dev-0.10). + It will violently change for a while, and it will definitely be in a + non-working state now and then. It should only be used for sneak-peaks and + discussions of the new features and designs. +- Once v0.10 is ready for real-life use, it will be merged into the master + branch (which is the reason why you should lock your dependency management + tool to v0.9.x and only migrate to v0.10 when both you and v0.10 are ready + for it). In the ideal case, v0.10 will be the basis for the future v1.0 + release, but we cannot provide an ETA at this time. + +## Instrumenting applications + +[![code-coverage](http://gocover.io/_badge/github.com/prometheus/client_golang/prometheus)](http://gocover.io/github.com/prometheus/client_golang/prometheus) [![go-doc](https://godoc.org/github.com/prometheus/client_golang/prometheus?status.svg)](https://godoc.org/github.com/prometheus/client_golang/prometheus) + +The +[`prometheus` directory](https://github.com/prometheus/client_golang/tree/master/prometheus) +contains the instrumentation library.

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/ +// +// A fifth "type" of metric is Untyped. It behaves like a Gauge, but signals the +// Prometheus server not to assume anything about its type. +// +// In addition to the fundamental metric types Gauge, Counter, Summary, +// Histogram, and Untyped, 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, +// HistogramVec, and UntypedVec. +// +// 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, +// Histogram, and Untyped are interfaces themselves while GaugeVec, CounterVec, +// SummaryVec, HistogramVec, and UntypedVec are not. +// +// To create instances of Metrics and their vector versions, you need a suitable +// …Opts struct, i.e. GaugeOpts, CounterOpts, SummaryOpts, HistogramOpts, or +// UntypedOpts. +// +// 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). That will happen 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 marke the Collector “unchecked”. No +// checks are porformed 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 situatios 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.

There are two caveats: +// +// First, in more complex programs, global state is often quite problematic. +// That's the reason why the metrics constructors in the prometheus package do +// not interact with the global prometheus.DefaultRegisterer on their own. You +// are free to use the Register or MustRegister functions to register them with +// the global prometheus.DefaultRegisterer, but you could as well choose a local +// Registerer (usually created with prometheus.NewRegistry, but there are other +// scenarios, e.g. testing). +// +// The second issue is that registration may fail, e.g. if a metric inconsistent +// with the newly to be registered one is already registered. But how to signal +// and handle a panic in the automatic registration with the default registry? +// The only way is panicking. While panicking on invalid input provided by the +// programmer is certainly fine, things are a bit more subtle in this case: You +// might just add another package to the program, and that package (in its init +// function) happens to register a metric with the same name as your code. Now, +// all of a sudden, either your code or the code of the newly imported package +// panics, depending on initialization order, without any opportunity to handle +// the case gracefully. Even worse is a scenario where registration happens +// later during the runtime (e.g. upon loading some kind of plugin), where the +// panic could be triggered long after the code has been deployed to +// production. A possibility to panic should be explicitly called out by the +// Must… idiom, cf. prometheus.MustRegister. But adding a separate set of +// constructors in the prometheus package called MustRegisterNewCounterVec or +// similar would be quite unwieldy. Adding an extra MustRegister method to each +// metric, returning the registered metric, would result in nice code for those +// using the method, but would pollute every single metric interface for +// everybody avoiding the global registry. +// +// To address both issues, the problematic auto-registering and possibly +// panicking constructors are all in this package with a clear warning +// ahead. And whoever cares about avoiding global state and possibly panicking +// function calls can simply ignore the existence of the promauto package +// altogether. +// +// A final note: There is a similar case in the net/http package of the standard +// library. It has DefaultServeMux as a global instance of ServeMux, and the +// Handle function acts on it, panicking if a handler for the same pattern has +// already been registered. However, one might argue that the whole HTTP routing +// is usually set up closely together in the same package or file, while +// Prometheus metrics tend to be spread widely over the codebase, increasing the +// chance of surprising registration failures.
