It is possible to check the status of gmirror with Nagios and NRPE using the following port:
$ cat /usr/ports/net-mgmt/nagios-geom/pkg-descr This is a small Nagios plugin written in PERL and designed to monitor the state of FreeBSD GEOM devices (specifically mirrors and striped volumes) from Nagios. WWW: http://www.geocities.com/ntb4real/proj/geom.htm
Install the port:
sudo portmaster /usr/ports/net-mgmt/nagios-geom/
Add the following line to /usr/local/etc/nrpe.cfg:
command[check_geom]=/usr/local/libexec/nagios/check_geom mirror gm0
Of course, if the gmirror is called something else, change the line accordingly.
Remember to restart NRPE after changing the config:
sudo /usr/local/etc/rc.d/nrpe2 restart
Define a service on the Nagios server, in /usr/local/etc/nagios/objects/services.cfg:
define service{ use generic-service hostgroup_name geom-servers service_description nrpe_check_geom check_command check_nrpe2!check_geom }
I then add the host to the group geom-servers on the nagios server, which just tells it to run the check check_nrpe2!check_geom on all members of the group.
Read on for a way to do this without the port, should you want to (old information below here, use the port if possible):
I found a simple script to monitor the status of gmirror on a server in nagios. I found it on this page, the usual thanks to Søren Klintrup for making it available to the public. I do the following to make it work on an existing NRPE installation:
sudo fetch -o /usr/local/libexec/nagios/check_gmirror http://www.klintrup.dk/soren/gmirror/check_gmirror.sh sudo chmod +x /usr/local/libexec/nagios/check_gmirror sudo ee /usr/local/etc/nrpe.cfg ...and add "command[check_gmirror]=/usr/local/libexec/nagios/check_gmirror" in the command section near the bottom... sudo /usr/local/etc/rc.d/nrpe2 restart
Define a service on the Nagios server, in /usr/local/etc/nagios/objects/services.cfg:
define service{ use generic-service hostgroup_name gmirror-servers service_description nrpe_check_gmirror check_command check_nrpe2!check_gmirror }
I then add the host to the hostgroup gmirror-servers on the nagios server.
