Hi @jkroepke , Can I have an initial review on this please?

[jkroepke]

it's an initial review yet. I have to test it on my machine.

[soheilrt]

Hi @jkroepke, Would it be possible to approve workflows for this PR? I don't have a windows machine and it's a bit pain to test my changes every time on a virtual machine.

[soheilrt]

Hi again @jkroepke , I guess PR is ready for a review, I would appreciate it if you could have a look at it when you have time.

Also, Could you please share the release schedule?

[soheilrt]

Hi @jkroepke, did you have time to have a look at my PR? It's a bit crucial for us to have these metrics. I would really appreciate your help on this.

[jkroepke]

tested on local system, seems working for me. I have one question left.

[jkroepke]

Thanks
