haproxy_
Name
haproxy_ - Graph stats from the haproxy daemon
Applicable Systems
Any haproxy host
Configuration
This is a wildcard plugin to support fetching status from multiple instances of haproxy that each need a distinct configurations, e.g.:
haproxy_backend
and
haproxy_frontend
Each with a separate configuration. The following example shows the default URL used by the plugin for the imaginary backend:
[haproxy_backend]
env.url http://localhost/haproxy-status;csv;norefresh
If you need authenticated access to the URL you can specify the username and password in the URL. For example:
[haproxy_backend]
env.url http://munin:spamalot@localhost/haproxy-status;csv;norefresh
This will provide for HTTP basic authentication.
