nagios-icinga-checks

The here listed nagios-icinga-checks were created during my work for credativ GmbH.

What to do with the checks

The usage of the checks depends on what kind of checks they are:

• nrpe plugins must be copied to the monitoring client
• normal checks must be run on the monitoring server

How to use check_openvpn

The plugin is a normal check which must be run on the monitoring server. It queries the target OpenVPN server and outputs OK, etc.

$ python check_openvpn --help
usage: check_openvpn [-h] [-p PORT] [-t] host

positional arguments:
  host                  the OpenVPN host name or ip

optional arguments:
  -h, --help            show this help message and exit
  -p PORT, --port PORT  set port number
  -t, --tcp             use tcp instead of udp

How to use check_puppetagent

The plugin is an NRPE check and needs to be run on the monitoring client, thus the client which Puppetagent needs to be monitored.

$ python check_puppetagent --help
usage: check_puppetagent [-h] [-w WARN] [-c CRIT]

optional arguments:
  -h, --help            show this help message and exit
  -w WARN, --warn WARN  seconds after last Puppet run which issues a warning
  -c CRIT, --crit CRIT  seconds after last Puppet run which are critica  

How to use check_systemd

The plugin is an NRPE check and needs to be run on the monitoring client. It checks if there are any failed systemd units (degraded state). Use it to make sure all services that should be up are actually up.

$ /usr/lib/nagios/plugins/check_systemd
OK: state is “running”
