metrics
=======
[![Build Status](https://travis-ci.org/codahale/metrics.png?branch=master)](https://travis-ci.org/codahale/metrics)
A Go library which provides light-weight instrumentation for your application.
For documentation, check [godoc](http://godoc.org/github.com/codahale/metrics).

// Package metrics provides minimalist instrumentation for your applications in
// the form of counters and gauges.
//
// Counters
//
// A counter is a monotonically-increasing, unsigned, 64-bit integer used to
// represent the number of times an event has occurred. By tracking the deltas
// between measurements of a counter over intervals of time, an aggregation
// layer can derive rates, acceleration, etc.
//
// Gauges
//
// A gauge returns instantaneous measurements of something using signed, 64-bit
// integers. This value does not need to be monotonic.
//
// Histograms
//
// A histogram tracks the distribution of a stream of values (e.g. the number of
// milliseconds it takes to handle requests), adding gauges for the values at
// meaningful quantiles: 50th, 75th, 90th, 95th, 99th, 99.9th.
//
// Reporting
//
// Measurements from counters and gauges are available as expvars. Your service
// should return its expvars from an HTTP endpoint (i.e., /debug/vars) as a JSON
// object.
