check_munin

You can use check_munin.pl to get info for any plugins that munin-node can run.

If you have a lot of munin-nodes you should definetly follow instructions here : http://munin.projects.linpro.no/wiki/HowToContactNagios

Even in this case check_munin.pl could be usefull instead of check_dummy to get fresh data.

use :

check_service_freshness=1
service_freshness_check_interval=60


If you don't have many hosts you should be fine using nagios (active checks) and munin.

Setup :

# 'check_munin' command definition
define command{

command_name check_munin
command_line /usr/lib/nagios/plugins/check_munin.pl -H $HOSTADDRESS$ -M $ARG1$ -w $ARG2$ -c $ARG3$

}


Sample service definition :

# Will generate a warn or crit if any disk usage is above 80 resp 95
# otherwise get a summary of disk usage
define service{

service_description disk-usage
check_command check_munin!df!80!95
}


define service{

service_description mysql-threads
check_command check_munin!mysql_threads!100!200

}


Runs ok on GNU/Linux (Ubuntu and Red Hat).
Need some work to sanitize more modules, patch welcome.
