Prometheus regex match on different labels

Question

I want to do a filter in prometheus based on all labels. Say if my labels in prometheus are instance, cpu, mode for the query node_cpu_seconds_total, i want to do an operation like,

input = ".*abc.*"

node_cpu_seconds_total{instance=~".*abc.*" or mode=~".*abc.*" or cpu=~".*abc.*"}

Basically i want my regex to be compared with all label values . Is there any solution to achieve this?

Answer 1

You cannot achieve this with vector selectors but you can use union operator OR to get the union of selections:

node_cpu_seconds_total{instance=~".*abc.*"} or \
node_cpu_seconds_total{mode=~".*abc.*"} or \
node_cpu_seconds_total{cpu=~".*abc.*"}

BUT there is no all label values selector - meaning you have to specify all labels.

Note that this is rather an odd kind of request.
