Prometheus: Should alerting rules names really be valid metric names ?

[austil]

Hi, on the documentation page about Recording rules, it's mentioned that :

The names of recording and alerting rules must be valid metric names

... meaning that it should match the regex [a-zA-Z_:][a-zA-Z0-9_:]*.

However, in my own configuration, I've used spaces in my alert names like Daily Peak and it's working just fine. Indeed, alert names end up as a label value (allowing any Unicode Character) as in ALERTS{alertname="Daily peak"} and not as a metric or label name (constrained to an ascii regex).

So I'm wondering if alerting rules names should really be valid metric names ?
If not I'll make the pull request to add clarification on this subject.

Thx for this piece of software :wink:

So either this is a regression and needs to be fixed, or it could be that this has been around so long that we might have to make it the official behaviour.

I also have lots of spaces in my alert names, since a very long time. It works just fine.
