HAProxy module

This module collects stats from HAProxy. It supports collection from TCP sockets, UNIX sockets, or HTTP with or without basic authentication.

Metricbeat can collect two metricsets from HAProxy: info and stat. info is not available when using the stats page.

Before you can use Metricbeat to collect stats, you must enable the stats module in HAProxy. You can do this a couple of ways: configure HAProxy to report stats via a TCP or UNIX socket, or enable the stats page.

To enable stats reporting via any local IP on port 14567, add the following line to the global or default section of the HAProxy config:

 stats socket 127.0.0.1:14567

To enable stats reporting via a UNIX socket, add the following line to the global or default section of the HAProxy config:

 stats socket /path/to/haproxy.sock mode 660 level admin

To enable the HAProxy stats page, add the following lines to the HAProxy config, then restart HAProxy. The stats page in this example will be available to any IP on port 14567 after authentication.

 listen stats
   bind 0.0.0.0:14567
   stats enable
   stats uri /stats
   stats auth admin:admin

The HAProxy metricsets are tested with HAProxy versions from 1.6 to 1.8.

The HAProxy module supports the standard configuration options that are described in Modules. Here is an example configuration:

metricbeat.modules:
- module: haproxy
  metricsets: ["info", "stat"]
  period: 10s
  # TCP socket, UNIX socket, or HTTP address where HAProxy stats are reported
  # TCP socket
  hosts: ["tcp://127.0.0.1:14567"]
  # UNIX socket
  #hosts: ["unix:///path/to/haproxy.sock"]
  # Stats page
  #hosts: ["http://127.0.0.1:14567"]
  username : "admin"
  password : "admin"
  enabled: true

This module supports TLS connections when using ssl config field, as described in SSL. It also supports the options described in Standard HTTP config options.

The following metricsets are available:
