This is a rewrite of http://www.nagiosexchange.org/cgi-bin/page.cgi?g=Detailed%2F2515.html;d=1

You can use check_munin_rrd.pl to get info for any plugins that munin-node can run directly on the munin server (no need to connect to the remote hosts anymore, so no locks on node)


Setup :


#check_munin_rrd command definition
define command{

command_name check_munin
command_line /usr/lib/nagios/plugins/check_munin_rrd.pl -H $HOSTALIAS$ -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, check freshness of munin data (if munin is not running on node) patchs welcome.
