I have a variable :

serviceName : label_values(go_info, name)

ex: "AAA-deployment" And metric in prometheus looklike:

metric_name{pod="AAA-deployment-XXXXX" ,name="k8s_POD_AAA-deployment-XXXX"}

If you want filer metric have prefix is a constant word we can use:

label_values(metric_name{pod=~"CONST_PREFIX*"},name)

But how to filter metric_name's label have prefix is other label in prometheus? I try

label_values(metric_name{pod=~"$serviceName*"},name)

but it not work

you can use the regex selector: metric_name{label=~"prefix*"}: https://prometheus.io/docs/prometheus/latest/querying/basics/#instant-vector-selectors – star67 Dec 06 '22 at 07:07
but the prefix is choose by other variable $serviceName , not constant so I think your answer is not work – vuhoanghiep1993 Dec 06 '22 at 08:59
