This might break + existing setups that used to export inconsistent metrics. +* [CHANGE] Pushing to Pushgateway moved to package `push` and changed to allow + arbitrary grouping. +* [CHANGE] Removed `SelfCollector`. +* [CHANGE] Removed `PanicOnCollectError` and `EnableCollectChecks` methods. +* [CHANGE] Moved packages to the prometheus/common repo: `text`, `model`, + `extraction`. +* [CHANGE] Deprecated a number of functions. +* [FEATURE] Allow custom registries. Added `Registerer` and `Gatherer` + interfaces. +* [FEATURE] Separated HTTP exposition, allowing custom HTTP handlers (package + `promhttp`) and enabling the creation of other exposition mechanisms. +* [FEATURE] `MustRegister` is variadic now, allowing registration of many + collectors in one call. +* [FEATURE] Added HTTP API v1 package. +* [ENHANCEMENT] Numerous documentation improvements. +* [ENHANCEMENT] Improved metric sorting. +* [ENHANCEMENT] Inlined fnv64a hashing for improved performance. +* [ENHANCEMENT] Several test improvements. +* [BUGFIX] Handle collisions in MetricVec. + +## 0.7.0 / 2015-07-27 +* [CHANGE] Rename ExporterLabelPrefix to ExportedLabelPrefix. +* [BUGFIX] Closed gaps in metric consistency check. +* [BUGFIX] Validate LabelName/LabelSet on JSON unmarshaling. +* [ENHANCEMENT] Document the possibility to create "empty" metrics in + a metric vector. +* [ENHANCEMENT] Fix and clarify various doc comments and the README.md. +* [ENHANCEMENT] (Kind of) solve "The Proxy Problem" of http.InstrumentHandler. +* [ENHANCEMENT] Change responseWriterDelegator.written to int64. + +## 0.6.0 / 2015-06-01 +* [CHANGE] Rename process_goroutines to go_goroutines. +* [ENHANCEMENT] Validate label names during YAML decoding. +* [ENHANCEMENT] Add LabelName regular expression. +* [BUGFIX] Ensure alignment of struct members for 32-bit systems. + +## 0.5.0 / 2015-05-06 +* [BUGFIX] Removed a weakness in the fingerprinting aka signature code. + This makes fingerprinting slower and more allocation-heavy, but the + weakness was too severe to be tolerated. +* [CHANGE] As a result of the above, Metric.Fingerprint is now returning + a different fingerprint. To keep the same fingerprint, the new method + Metric.FastFingerprint was introduced, which will be used by the + Prometheus server for storage purposes (implying that a collision + detection has to be added, too). +* [ENHANCEMENT] The Metric.Equal and Metric.Before do not depend on + fingerprinting anymore, removing the possibility of an undetected + fingerprint collision. +* [FEATURE] The Go collector in the exposition library includes garbage + collection stats. +* [FEATURE] The exposition library allows to create constant "throw-away" + summaries and histograms. +* [CHANGE] A number of new reserved labels and prefixes. + +## 0.4.0 / 2015-04-08 +* [CHANGE] Return NaN when Summaries have no observations yet. +* [BUGFIX] Properly handle Summary decay upon Write(). +* [BUGFIX] Fix the documentation link to the consumption library. +* [FEATURE] Allow the metric family injection hook to merge with existing + metric families. +* [ENHANCEMENT] Removed cgo dependency and conditional compilation of procfs. +* [MAINTENANCE] Adjusted to changes in matttproud/golang_protobuf_extensions. + +## 0.3.2 / 2015-03-11 +* [BUGFIX] Fixed the receiver type of COWMetric.Set(). This method is + only used by the Prometheus server internally. +* [CLEANUP] Added licenses of vendored code left out by godep. + +## 0.3.1 / 2015-03-04 +* [ENHANCEMENT] Switched fingerprinting functions from own free list to + sync.Pool. +* [CHANGE] Makefile uses Go 1.4.2 now (only relevant for examples and tests). + +## 0.3.0 / 2015-03-03 +* [CHANGE] Changed the fingerprinting for metrics. 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.

Hovever, 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. +// +// 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. +// +// 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 DefaultRegistry 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 DefaultRegistry. 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 DefaultRegistry 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. (The top-level functions in the prometheus package are +// deprecated.) +// +// Pushing to the Pushgateway +// +// Function for pushing to the Pushgateway can be found in the push sub-package. +// +// Other Means of Exposition +// +// More ways of exposing metrics can easily be added.
