Icinga Check Scripts

Various check scripts for use in icinga.

All scripts support option --help, so call ./scriptname --help for more information.

load_per_cpu.sh

Icinga plugin to check load average per CPU. Shows 1min, 5min 15min average per CPU. Different to check_load, the load is divided by the number of CPU units and therefore normalized. So the same warning and critical levels fit for any server.

mountpoint.sh

Icinga plugin to check whether a given path is available. Detects problems, e.g. with glusterfs: In case of a problem, there is an error message such as "socket not connected". Called with path to check.

Installation

Install

Checkout to a path, e.g. /opt/icinga-checks:

cd /opt
sudo git co https://mrw.sh/admin-scripts/icinga-checks.git

Update

cd /opt/icinga-checks

Configure

Go to Icinga Director, in Commands add one:

• Command type: Plugin Check Command
• Command name: load per cpu
• Command: check_by_ssh

After adding the command, add the following parameters:

-C /opt/icinga-checks/load_per_cpu.sh
-H $host.name$
-oStrictHostKeyChecking=no

The last argument -oStrictHostKeyChecking=no is a key only ith no value.

To check mountpoint of /var/volumes use argument name -C with value /opt/icinga-checks/mountpount.sh /var/volumes.

Then create a new Service Template, give it a name. e.g. load per cpu and assign the check command just created.

Finally add a service, again you can use the same name and import the template just created, then assign the hosts to check. I use a host template for all linux servers, so the command is run in each of them.

Don't forget to deploy the activity log in Icinga Director.
