# prometheus-haskell [![Build Status](https://travis-ci.org/fimad/prometheus-haskell.svg?branch=master)](https://travis-ci.org/fimad/prometheus-haskell)

This repository contains a collection of libraries that can be used to

instrument a Haskell application with metrics that can be consumed by the

[Prometheus](http://prometheus.io) monitoring system and time series database.

API documentation can be found on each libraries respective hackage page:

[prometheus-client](http://hackage.haskell.org/package/prometheus-client),

[prometheus-metrics-ghc](http://hackage.haskell.org/package/prometheus-metrics-ghc),

[wai-middleware-prometheus](http://hackage.haskell.org/package/wai-middleware-prometheus).

The purposes of the libraries are outline below, and an example application can

be found under the

[example](https://github.com/fimad/prometheus-haskell/tree/master/example)

folder in the root directory of the git repository.

## prometheus-client [![Hackage](https://img.shields.io/hackage/v/prometheus-client.svg)](https://hackage.haskell.org/package/prometheus-client)

This is the base library that defines the core data types and metrics. It has a

few dependencies and is intended to provide the minimum functionality required

to interact with Prometheus.

## prometheus-metrics-ghc [![Hackage](https://img.shields.io/hackage/v/prometheus-metrics-ghc.svg)](https://hackage.haskell.org/package/prometheus-metrics-ghc)

This library provides custom metrics that an application can register that

expose information from GHC's runtime system. It is provided as a separate

package to keep the GHC specific dependencies out of the prometheus-client

library.

## wai-middleware-prometheus [![Hackage](https://img.shields.io/hackage/v/wai-middleware-prometheus.svg)](https://hackage.haskell.org/package/wai-middleware-prometheus)

This library provides WAI middleware that allows for easy integration of the

Prometheus client library into existing WAI apps. The middleware will by default

automatically instrument a WAI app with common HTTP metrics and respond to GET

requests on the /metrics endpoint.
