#

# Plugin to monitor an smstools installation

#

# Usage: Link or copy into the munin-node plugin directory, name it according

# to your SMS Modem as known to smsd. e.g. smstools_GSM1

#

#

# Installation:

#

# SMSD:

# Configure smsd to output his statistics by adding the following to /etc/smsd.conf:

#

# stats = /var/log/smsd_stats

# stats_interval = 300

#

#

# Munin:

# If your statistics directory is non-standard, configure it as

# statsdir in the munin-plugin configuration

# In case you do not want your statistics-dump from smsd deleted after reading,

# set env.cleanup to false. If you want cleanup to work, run the plugin as root.

#

# [smstools*]

# user root

# env.statsdir /var/log/smsd_stats

# env.cleanup true

#

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

# installation scripts):
