I'm using flexlm_exporter to export my license usage to Prometheus and from Prometheus to custom service (Not Grafana).
As you know Prometheus hides missing values.
However, I need those missing values in my metric values, therefore I added to my prom query or vector(0)
For example:
flexlm_feature_used_users{app="vendor_lic-server01",name="Temp"} or vector(0)
This query adds a empty metric with zero values.
My question is if there's a way to merge the zero vector with each metric values?
Edit:
I need grouping, at least for a user and name labels, so vector(0) is probably not the best option here?
I tried multiple solutions in different StackOverflow threads, however, nothing works.
Please assist.
If you do
sum(flexlm_feature_used_users{app="vendor_lic-server01",name="Temp"} or vector(0))
you should get what you're looking for, but you'll lose possibility to dogroup by
, sincevector(0)
doesn't have any labels.
