Munin plugin to monitor lighttpd 2.x statistics

Plugin Version 1.1

Install:

Copy this script to the directory of your other munin plugins

(e.g. /usr/share/munin/plugins) and make it executeable (chmod +x).

Then issue any of the following commands to enable the graphs:

ln -s path_to_this_script /etc/munin/plugins/lighttpd_requests

ln -s path_to_this_script /etc/munin/plugins/lighttpd_connections

ln -s path_to_this_script /etc/munin/plugins/lighttpd_traffic

ln -s path_to_this_script /etc/munin/plugins/lighttpd_statuscodes

Also ensure that lighttpd has mod_status enabled and that your

config contains a status.info action.

Adjust the STATUS_URL below if needed.

Example lighttpd 2.x config: if req.path == "/status" { status.info; }
