Looked around to find out if there is one already and I couldn’t find any.

I’ve created a multifunctional plugin for Munin for monitoring Cherokee server.

DOWNLOAD HERE

It’s written in Ruby. So far I can confirm that it’s compatible with Munin 1.3.4 and Cherokee 0.11.3 on Gentoo.

It gets data from the server_info module available under /about , which has to be set to at least normal.

Plugin graphs will appear under cherokee category and I believe it allows you to monitor multiple servers from single munin-node as it uses the host field.

Plugin can monitor :

• Number of connections, Active, Open and Reusable
• Number of modules Loaded
• Data Transferred by the Server
• Data Transfer rate, but this is just a concept as it doesn’t yield usable data after a while.

How to use it

Place it in directory like

/usr/local/lib/munin/plugins

add executable bit

 chmod +x /usr/local/lib/munin/plugins/cherokee__type_.rb

link from /etc/munin/plugins

cd /etc/munin/plugins
ln -s /usr/local/lib/munin/plugins/cherokee__type_.rb cherokee_hostname_type_conn
ln -s /usr/local/lib/munin/plugins/cherokee__type_.rb cherokee_hostname_type_mod
ln -s /usr/local/lib/munin/plugins/cherokee__type_.rb cherokee_hostname_type_data
ln -s /usr/local/lib/munin/plugins/cherokee__type_.rb cherokee_hostname_type_rate

restart munin-node

/etc/init.d/munin-node restart
