How to exclude all labels containing '3scale' in their name during FEDERATION phase

[Fabio Marzotti]

Hi, I need to exclude all labels containing an error name. For example those starting with '3scale'.

This in order to avoid this error during federation phase:

"prometheus       | level=warn ts=2020-05-25T18:15:57.094907355Z caller=scrape.go:867 component="scrape manager" scrape_pool=yyyyyyyyyyyy target="https://xxxxxxxxx:443/federate?match%5B%5D=%7B__name__%3D~%22.%2B%22%7D" msg="append failed" err="expected label name, got \"INVALID\""

May be is the match phase in  any case after federation process and then I'll get the same error ??

Thanks for the support, 

Fabio

Hi, thanks for your answer. That is a label name with mistake, I know this is an error but is a metric supplied by third parts software, so I can't modify it. I'm looking a way to exclude it from federation process..... how can do it?

thanks!

metric names must match regex [a-zA-Z_:][a-zA-Z0-9_:]*
and therefore must not start with a number.

I'm not sure but in that way you match only metric name and not label name, right?

My issue is on label name.

Maybe something like: match[]={__name__=~"[^0-9].*"}

Oh yes you are right.

That is not possible.
