# Prometheus Go client library

[![Build Status](https://travis-ci.org/prometheus/client_golang.svg?branch=master)](https://travis-ci.org/prometheus/client_golang)
[![Go Report Card](https://goreportcard.com/badge/github.com/prometheus/client_golang)](https://goreportcard.com/report/github.com/prometheus/client_golang)

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).
