Nagios plugin to provide monitoring of mdq-server instances.
The script uses a number of Perl modules. Most of them should already be installed on a system
running Nagios, but Monitoring::Plugin may need to be acquired separately. If you are running on
a RHEL-derived system with EPEL available, you can use yum install perl-Monitoring-Plugin.
To find out if the script will run on your system, you can invoke it against some of the provided data files:
$ ./check_mda_health -u test/up.json
MDQ_HEALTH OK - status is UP
$ ./check_mdq_health -u file:test/down.json
MDQ_HEALTH CRITICAL - status is DOWN
$ ./check_mdq_health -u file:test/degraded.json
MDQ_HEALTH WARNING - status is DEGRADED
If everything seems fine, copy check_mda_health into the directory where your other Nagios
plugins live. This is normally defined as $USER1$ in /etc/nagios/private/resource.cfg
as something like /usr/lib64/nagios/plugins.
You can then define a command based on this plugin in one of your configuration files as follows:
define command {
command_name check_mdq_health
command_line $USER1$/check_mdq_health --url $ARG1$ $ARG2$
}
A service check then looks like this:
define service {
use my-service-template
host_name mdq
service_description health
check_command check_mdq_health!http://mdq.example.org/health
}
