-
-This is the [Go](http://golang.org) client library for
-[Prometheus](http://prometheus.io). It has two separate parts, one for
-instrumenting application code, and one for creating clients that talk to the
-Prometheus HTTP API.
-
-## 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. See the
-[best practices section](http://prometheus.io/docs/practices/naming/) of the
-Prometheus documentation to learn more about instrumenting applications.
-
-The
-[`examples` directory](https://github.com/prometheus/client_golang/tree/master/examples)
-contains simple examples of instrumented code.
-
-## Client for the Prometheus HTTP API
-
-[![code-coverage](http://gocover.io/_badge/github.com/prometheus/client_golang/api/prometheus)](http://gocover.io/github.com/prometheus/client_golang/api/prometheus) [![go-doc](https://godoc.org/github.com/prometheus/client_golang/api/prometheus?status.svg)](https://godoc.org/github.com/prometheus/client_golang/api/prometheus)
-
-The
-[`api/prometheus` directory](https://github.com/prometheus/client_golang/tree/master/api/prometheus)
-contains the client for the
-[Prometheus HTTP API](http://prometheus.io/docs/querying/api/). It allows you
-to write Go applications that query time series data from a Prometheus
-server. It is still in alpha stage.
-
-## Where is `model`, `extraction`, and `text`?
-
-The `model` packages has been moved to
-[`prometheus/common/model`](https://github.com/prometheus/common/tree/master/model).
-
-The `extraction` and `text` packages are now contained in
-[`prometheus/common/expfmt`](https://github.com/prometheus/common/tree/master/expfmt).
-
-## Contributing and community
-
-See the [contributing guidelines](CONTRIBUTING.md) and the
-[Community section](http://prometheus.io/community/) of the homepage.

-// Collector is the interface implemented by anything that can be used by
-// Prometheus to collect metrics. A Collector has to be registered for
-// collection. See Registerer.Register.
-//
-// 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.
-type Collector interface {
- // Describe sends the super-set of all possible descriptors of metrics
- // collected by this Collector to the provided channel and returns once
- // 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.) This
- // method idempotently sends the same descriptors throughout the
- // lifetime of the Collector. 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.
- Describe(chan<- *Desc)
- // Collect is called by the Prometheus registry when collecting
- // metrics. The implementation sends each collected metric via the
- // provided channel and returns once the last metric has been sent. The
- // descriptor of each sent metric is one of those returned by
- // Describe. 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

-// Package prometheus 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).
-//
-// All exported functions and methods are safe to be used concurrently unless
-// specified otherwise.
-//
-// A Basic Example
-//
-// As a starting point, a very basic usage example:
-//
-// 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.
-//
-// 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.
-//
-// 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.
