// 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 Register, MustRegister, RegisterOrGet, and MustRegisterOrGet.
//
// The stock metrics provided by this package (like Gauge, Counter, Summary) 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 Prometheus 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 concurrent
// readers.

// Metric collects itself. Add it as an anonymous field to a struct that
// implements Metric, and call Init with the Metric itself as an argument.

// Package prometheus provides embeddable metric primitives for servers and
// standardized exposition of telemetry through a web services interface.
//
// All exported functions and methods are safe to be used concurrently unless
// specified otherwise.
//
// To expose metrics registered with the Prometheus registry, an HTTP server
// needs to know about the Prometheus handler. The usual endpoint is "/metrics".
//
// http.Handle("/metrics", prometheus.Handler())
//
// As a starting point a very basic usage example:
//
// package main
//
// import (
// "net/http"
//
// "github.com/prometheus/client_golang/prometheus"
// )
//
// var (
// cpuTemp = prometheus.NewGauge(prometheus.GaugeOpts{
// Name: "cpu_temperature_celsius",
// Help: "Current temperature of the CPU.",
// })
// hdFailures = prometheus.NewCounter(prometheus.CounterOpts{
// Name: "hd_errors_total",
// Help: "Number of hard-disk errors.",
// })
// )
//
// func init() {
// prometheus.MustRegister(cpuTemp)
// prometheus.MustRegister(hdFailures)
// }
//
// func main() {
// cpuTemp.Set(65.3)
// hdFailures.Inc()
//
// http.Handle("/metrics", prometheus.Handler())
// http.ListenAndServe(":8080", nil)
// }
//
//
// This is a complete program that exports two metrics, a Gauge and a Counter.
// It also exports some stats about the HTTP usage of the /metrics
// endpoint. (See the Handler function for more detail.)
//
// Two more advanced metric types are the Summary and Histogram.
//
// 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.
//
// Those are all the parts needed for basic usage. Detailed documentation and
// examples are provided below.
//
// Everything else this package offers is essentially for "power users" only. A
// few pointers to "power user features":
//
// All the various ...Opts structs have a ConstLabels field for labels that
// never change their value (which is only useful under special circumstances,
// see documentation of the Opts type).
//
// The Untyped metric behaves like a Gauge, but signals the Prometheus server
// not to assume anything about its type.
//
// Functions to fine-tune how the metric registry works: EnableCollectChecks,
// PanicOnCollectError, Register, Unregister, SetMetricFamilyInjectionHook.
//
// For custom metric collection, there are two entry points: Custom Metric
// implementations and custom Collector implementations. A Metric is the
// fundamental unit in the Prometheus data model: a sample at a point in time
// together with its meta-data (like its fully-qualified name and any number of
// pairs of label name and label value) that knows how to marshal itself into a
// data transfer object (aka DTO, implemented as a protocol buffer). A Collector
// gets registered with the Prometheus registry and manages the collection of
// one or more Metrics. Many parts of this package are building blocks for
// Metrics and Collectors. Desc is the metric descriptor, actually used by all
// metrics under the hood, and by Collectors to describe the Metrics to be
// collected, but only to be dealt with by users if they implement their own
// Metrics or Collectors. To create a Desc, the BuildFQName function will come
// in handy. Other useful components for Metric and Collector implementation
// include: LabelPairSorter to sort the DTO version of label pairs,
// NewConstMetric and MustNewConstMetric to create "throw away" Metrics at
// collection time, MetricVec to bundle custom Metrics into a metric vector
// Collector, SelfCollector to make a custom Metric collect itself.
//
// A good example for a custom Collector is the ExpVarCollector included in this
// package, which exports variables exported via the "expvar" package as
// Prometheus metrics.
