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.

CheckMK

Below are a few cmk cli examples that can be useful when developing a cmk plugin

# Service scan for exmaple.host
cmk --verbose --perfdata --debug example.host

# Clear prevous then detect plugins for sentry4_pdu_status
cmk --verbose --perfdata --debug -II --detect-plugins=sentry4_pdu_status example.host

# Check discovery for emaple.host
cmk --verbose --perfdata --check-discovery example.host

# Run isis_adjacency plugin on example.host
cmk --verbose --perfdata --plugins=sentry4_pdu_status example.host
