A nagios plugin I wrote, which checks the number of outdated ports on a system. If the number exceeds the configured limits, WARNING or CRITICAL is returned. The plugin depends on the file <code>/tmp/check_portmaster.tmp</code> which should contain the output from the <code>portmaster -L</code> command. Obviously, this also means that portmaster is required for this to make any sense.

A nagios plugin I wrote, which checks the number of outdated ports on a system. If the number exceeds the configured limits, WARNING or CRITICAL is returned. The plugin runs pkg_info -o and thus only needs the ports INDEX-x file to be up to date.

Download the plugin

The plugin can be downloaded to the correct place (and made executable) with the following commands: 

sudo fetch -o /usr/local/libexec/nagios/check_port_versions http://www.gibfest.dk/check_port_versions
sudo chmod +x /usr/local/libexec/nagios/check_port_versions

Feel free to check the source code to see what it does, it is very simple and well commented.

Configuring NRPE

Add the following line to /usr/local/etc/nrpe.cfg: 

command[check_port_versions]=/usr/local/libexec/nagios/check_port_versions

Remember to restart NRPE after changing the config: 

sudo /usr/local/etc/rc.d/nrpe2 restart

Updating ports

I add the following line to /etc/crontab to create an hourly updated /tmp/check_portmaster.tmp file: 

0	*	*	*	*	root	/usr/local/sbin/portmaster -L > /tmp/check_portmaster.tmp

To make the NRPE check work right away, run the following command manually: 

/usr/local/sbin/portmaster -L > /tmp/check_portmaster.tmp
