Open Stack

Hello Lars,

This is great, we have been using our own checks previously but having a
great and cleaned up option upstream is gold worth.

This was we can all collaborate on having this as a standard toolbox for
health checks.


Looking forward to see moving forward and would love to contribute, and
in the future roll this out across our companies.

Best regards
