Did you close this on purpose?

Both the metric and the label names would need some work; I would be happy to help you polish them.

I just realised I closed it by accident when adding the lastest commit, thank you so much for sending this message 😭

[cestef]

I would be very grateful if you could help me rename the metrics etc. I'm pretty new to the prometheus ecosystem...

No problem! You should prefix them with a name, in your case I think it's webscraper_ and suffix them with the unit, so:

Metrics should be in base units, so duration should be in seconds, and probably named webscraper_test_duration_seconds

heap_usage should probably be webscraper_heap_usage_bytes

CPU usage should ideally be in seconds and also allow users to calculate a total; that way they can calculate the % themselves as they need. If you can only do %, then webscraper_cpu_usage_percent would be OK.

bytes_in would be better as webscraper_in_bytes

Also, can you please sign your commits? See e.g. https://github.com/src-d/guide/blob/master/developer-community/fix-DCO.md

Thank you very much ! I'll update the metrics accordingly asap

Sorry for all the useless logs from github about me force-pushing commits or whatever, it was a complete mess so I just started over from scratch 😅 I renamed the metrics following what you said, so it should be all good now !

These are now the metrics exposed:

Any updates on this ? Would love to have my work featured :D
