HAProxy Exporter for Prometheus

This is a simple server that scrapes HAProxy stats and exports them via HTTP for Prometheus consumption.

Getting Started

To run it:

./haproxy_exporter [flags]

Help on flags:

./haproxy_exporter --help

For more information check the source code documentation. All of the core developers are accessible via the Prometheus Developers mailinglist.

Usage

HTTP stats URL

Specify custom URLs for the HAProxy stats port using the -haproxy.scrape-uri flag. For example, if you have set stats uri /baz,

haproxy_exporter -haproxy.scrape-uri="http://localhost:5000/baz?stats;csv"

Or to scrape a remote host:

haproxy_exporter -haproxy.scrape-uri="http://haproxy.example.com/haproxy?stats;csv"

Note that the ;csv is mandatory (and needs to be quoted).

If your stats port is protected by basic auth, add the credentials to the scrape URL:

haproxy_exporter  -haproxy.scrape-uri="http://user:[email protected]/haproxy?stats;csv"

Unix Sockets

As alternative to localhost HTTP a stats socket can be used. Enable the stats socket in HAProxy with for example:

stats socket /run/haproxy/admin.sock mode 660 level admin

The scrape URL uses the 'unix:' scheme:

haproxy_exporter -haproxy.scrape-uri=unix:/run/haproxy/admin.sock

Docker

To run the haproxy exporter as a Docker container, run:

docker run -p 9101:9101 quay.io/prometheus/haproxy-exporter -haproxy.scrape-uri="http://user:[email protected]/haproxy?stats;csv"
