Exactly, I develop a API which accept prometheus rule from web.
When user create a new rule, I want to add a fixed matcher(xxId="xxx"),
which label name is fixed and label value is various.
eg.
cpu_usage / avg_over_time(cpu_usage[5m] offset 24h) > 2 ->
cpu_usage{xxId="xxx"} / avg_over_time(cpu_usage{xxId="xxx"}[5m] offset
24h) > 2
So it seems like your web application will only handle the
alert-specific PromQL expression which ends up in the alert's "expr" field.
It seems like it would be straight forward to add the static label with
the dynamic value directly into the Prometheus alert using the labels:
field?
