# Plugin to monitor voip statistics.

#

# Parameters:

#

# 	config   (required)

# 	autoconf (optional - only used by munin-config)

#

# Bugs:

#       At least one SuSE netstat appears to report

#         "passive connections rejected because of time stamp"

#        We have never seen that, patch requested.

#

# Magic markers (optional - used by munin-config and some installation

# scripts):

#%# family=auto

#%# capabilities=autoconf

	# Most T1s have 23 channels, with one control channel. If you have more than

	# one T1, increase the limit here appropriately

	echo 'graph_args --upper-limit 22 -l 0'

	echo 'graph_scale no'

	echo 'graph_vlabel active connections'

	echo 'graph_category VOIP'

	echo 'graph_period second'

	echo 'graph_info This graph shows the number of PRI lines in use.'

	echo 'calls.label calls'

	echo 'calls.min 0'

	echo 'calls.info The number of calls per second.'

	exit 0

# it would be wise to put the following in a separate shell script that runs as root in

# cron, and dumps its output to a separate file for this plugin to read later on. Letting

# Munin plugins run as root is a security hole.
