- The title given to this article is incorrect due to [technical limitations]. The correct title is check_geom - NRPE gmirror and friends check.
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
Configuring Nagios
First I define a new 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 hosts that I want to run this check on to the group geom-servers on the nagios server, which makes Nagios run the check check_nrpe2!check_geom
on all members of the group.
Install the plugin
Just install the port:
sudo portmaster /usr/ports/net-mgmt/nagios-geom/
Configuring NRPE
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
