Regexp match in template

[fiala...@gmail.com]

Hi,

is it possible to make a regexp match in annotation?

I need to check, if label contains specific string.

function "regexMatch" not definedThank you.

See the template functions listed here:

https://prometheus.io/docs/prometheus/latest/configuration/template_reference/#strings

There is one called "match" which matches regular expressions. (Note that there is not one called "regexMatch")

You should also be able to use the go template global functions:

If this is for alerts, it might be simpler to use routing rules, with two different alert receivers.
