Template for new Checkmk Extensions

Checkmk extension for ...

Description

This is a template to develop Checkmk Extensions

Development

For the best development experience use VSCode with the Remote Containers extension. This maps your workspace into a checkmk docker container giving you access to the python environment and libraries the installed extension has.

Directories

The following directories in this repo are getting mapped into the Checkmk site.

• agents, checkman, checks, doc, inventory, notifications, pnp-templates, web are mapped into local/share/check_mk/
• agent_based is mapped to local/lib/check_mk/base/plugins/agent_based
• nagios_plugins is mapped to local/lib/nagios/plugins

Continuous integration

Local

To build the package hit Crtl+Shift+B to execute the build task in VSCode.

pytest can be executed from the terminal or the test ui.

Github Workflow

The provided Github Workflows run pytest and flake8 in the same checkmk docker conatiner as vscode.

checkmk_template's Issues

Nagios Core is crashing / starting with errror exitcode when starting the site

Hy @jiuka, first of all thanks for this template. I'm trying to build a snmp plugin for a different kind of PDu ( and im using your plugins as example.
So far so good. But i struggle with the dev container. whenever i start the site the Nagios part is kinda starting with an error.

Starting mkeventd...OK
Starting rrdcached...OK
Starting npcd...OK
Starting nagios.............ERROR
Starting apache...OK
Starting redis...OK
Initializing Crontab...OK

but it works.
as long as i don't change anything on the site. ( also the nagios.log seems fine)
as soon as i add a host ( or try to change anything else and i want to apply those changes the nagios core crashes and i lose the connection to the site. and i have to restart the nagios core in the cli and remove the .lock file first.
So somethings really odd here and i can't get my hear around it wehre to look, or where to start investigating. :/

Maybe you have an Idea
nagios.log
