Munin contributed plugins

# -*- encoding: iso-8859-1 -*-

#

# Wildcard-plugin to monitor DVB signal information via femon command line utility,

# E.g.

#    ln -s /usr/share/munin/plugins/femon_ /etc/munin/plugins/femon_adapter0

# ...will monitor /dev/dvb/adapter0.

# Parameters

# 	femonpath     - Specify path to femon program (Default: /usr/bin/femon)

#       graph_args    - Specify graph args (Default: --lower-limit 0 --upper-limit 100 --rigid)

# Author: Nicolas Knotzer  <nknotzer@gmail.com>

# v1.0 02/10/2011

# v1.1 20/10/2011 - Prints OSError.strerror in verbose mode, uses rsplit instead of split for parsing femon output

# v1.2 21/10/2011 - Uses subprocess.Popen instead of subprocess.check_output for better compatibility with older python versions (i.e. works with python version >= 2.4)
