[ulikl]

Is there an existing issue for this?

• [X] I have searched the existing issues

Current Behavior

I would like to monitor the fleet functionality via Prometheus metrics. I found this was already implemented and merge via PR "Add Prometheus metrics to Fleet #769" at May 13, 2022.

The fleet controller has no prometheus metrics code included in release 0.5.1 (released Jan 23) and master branch.

But the code is no longer there. Just the modules are still in go.mod and go.sum. What happend to this feature?

Expected Behavior

I would expect metrics at the controller endpoint /metrics on port 6060

Steps To Reproduce

No response

Environment

- Architecture: amd64
- Fleet Version: 0.5.1
