Munin plugin for Cherokee web server

#!/usr/bin/env python

# Munin Plugin for Cherokee in Python
# Based on the work of Mateusz Pawlowski: http://www.mobygeek.net/projects/files/cherokee__type_.rb
# Coded by the not-python-programmer Jose Luis Salas <<josacar at gmail dot com>>  ;)

#%# family=contrib
# Cherokee has to have $host/about enabled with server info set to normal
# Or you can change the variables below as you wish
# Handling arguments
#
# cherokee_host_type_data Shows data transferred
# cherokee_host_type_rate Shows data rate transfer
# cherokee_host_type_mod Shows Modules
# cherokee_host_type_conn Shows connections

# USAGE:
# cp /home/user/cherokee__type_.py /usr/share/munin/plugins/cherokee__type_
# chmod +x /usr/share/munin/plugins/cherokee__type_
# ln -s /usr/share/munin/plugins/cherokee__type_ cherokee_host_type_data
# ln -s /usr/share/munin/plugins/cherokee__type_ cherokee_localhost_type_data
# ln -s /usr/share/munin/plugins/cherokee__type_ cherokee_localhost_type_conn
# ln -s /usr/share/munin/plugins/cherokee__type_ cherokee_localhost_type_mod
# ln -s /usr/share/munin/plugins/cherokee__type_ cherokee_localhost_type_rate
