check_port_versions - NRPE pkg_version check
check_port_versions is a nagios plugin I wrote, which checks the number of outdated ports installed on a FreeBSD system, compared to what is in
/usr/ports. 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.
Add the following line to
Remember to restart NRPE after changing the config:
sudo /usr/local/etc/rc.d/nrpe2 restart
I update ports daily from
/etc/crontab with the following
#update ports 0 12 * * * root /usr/sbin/portsnap cron && /usr/sbin/portsnap -I update
Note: The above
/etc/crontab line will download the latest snapsnot and update the ports index files. The ports themselves will not be extracted. As explained in the portsnap manpage, it is a bad idea to automatically update /etc/ports - bad things will happen if you accidently update while installing something. This means that you should run
portsnap update before installing/upgrading any ports.
