CheckMK || Docker Monitoring

DerMeldos

You need to pull the agent plug-in from your monitoring site at first.

root@FILEFLOWS0734:~# wget http://10.73.136.132/monitoring/check_mk/agents/plugins/mk_docker.py

Install the plug-in to the agents plug-in folder (usually /usr/lib/check_mk_agent/plugins).

install -m 0755 mk_docker.py /usr/lib/check_mk_agent/plugins

Note, that the docker Python library is required (not docker-py). At least Version 2.6.1 is necessary. You can easily check this by entering python on the command line:

root@linux# python3
Python 3.8.10 (default, Nov 26 2021, 20:14:08)
[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import docker
>>> docker.version
'5.0.3'

If you now perform the service discovery in Checkmk and activate the changes, you should find some new services that affect the Docker node itself:
