Introduce a "AllowList" for label values

[Andreas Wederbrand]

Hi!

I didn't find how in the documentations so I added this

https://github.com/prometheus/prometheus/issues/8375

Turns out it might be possible using.

But, did I missunderstand what a "label name" is in regards to labelmap and labelkeep?

It sounds like this is to keep labels entirly, not the values of them.

To be clear. This is what I would like for all metrics and from all targets

http_request_duration_seconds_count{client_name="the app"} 1

http_request_duration_seconds_count{client_name="the new app"} 1

http_request_duration_seconds_count{client_name="bogus guy 1"} 1

http_request_duration_seconds_count{client_name="bogus guy 2"} 1

turns into 

http_request_duration_seconds_count{client_name="the app"} 1

http_request_duration_seconds_count{client_name="the new app"} 1

http_request_duration_seconds_count{client_name="OTHER"} 2

"the app" and "the new app" would be in a AllowList for all metrics but other values should either be dropped or, better, bunched together as OTHER.

Cheers.

Doing math in metric_relabel_configs is not possible. The only way to fix this is with a recording rule, or to fix the source data.

An "AllowList" wouldn't solve this either. Prometheus does not manipulate values on ingestion, this is intentional. It only stores exactly what is exposed.
