From Debuntu

This set up was made on Debian Lenny

Apache Plugin

The default install of Munin on Debian Lenny comes with 3 apache backend:

• apache_processes
• apache_accesses
• apache_volume

The first one works out of the box, while the 2 others depend on the status module of Apache. As such, Apache needs to be configured to use this module, moreover, the ExtendedStatus must be enabled.

apache2 server config

First make sure that status module is enabled:

# a2enmod status

Then, edit /etc/apache2/mods-available/status.conf and add, just above <Location /server-status> :

ExtendedStatus On

Then, restart the service:

# /etc/init.d/apache2 restart

munin node config

Link the plugins to /etc/munin/plugins:

# ln -s /usr/share/munin/plugins/apache_accesses /etc/munin/plugins/apache_accesses
# ln -s /usr/share/munin/plugins/apache_volume /etc/munin/plugins/apache_volume

and restart munin-node

# /etc/init.d/munin-node restart
