check_munin_rrd.plnew version with some more checks
Network Monitoring Software - Download Nagios XI
Log Management Software - Nagios Log Server - Download
Netflow Analysis Software - Nagios Network Analyzer - Download can check various modules of a server running munin-node.
This is a rewrite of;d=1

You can use 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/ -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.

Does this plugin work with remote Munin (not installed with Nagios XI on the same host)?
It seems that this plugin doesn't use -H to establish a connection to the remote host, but rather it is trying to find munin's folder on the local host.

I can't guess your domain, please add the domain manually

No domain was configured in munin. Please help me in resolving this.
Owner's reply

You can specify the domain with -d option, however you should look in /var/lib/munin (or something like that) to see if you use an FQDN or not under the domain directory. This depends on your munin configuration.

Hi Nagios Community,

Just wanted to say that this plugin is great, managed to get in contact with one of the developers and they were a great help in aiding me.

I'd recommend using Munin and Nagios on the same host, skipping the need for NSCA configuration. That produced the desired result for me.

Thanks again on an excellent plugin!
