How to get all metric names from Prometheus server filtered by a particular label

[Amey Barve]

We want to get all metric names from Prometheus server filtered by a particular label.

Step 1 : Used following query to get all metric names, query succeeded with all metric names.

curl -g 'http://localhost:9090/api/v1/label/__name__/values

Step 2 : Used following query to get all metrics names filtered by label, but query still returned all metric names without filtering those metrics which do not have job label equal to "prometheus"

curl -g 'http://localhost:9090/api/v1/label/__name__/values?match[]={job!="prometheus"}'

Can somebody please help me filter all metric names by label over http? 

Thanks

Your second query is using not-equals. I would expect it to return all metrics names that do not have job="prometheus". Seems to be working correctly.

The second query still returns the exact same results as that of first even though all the metrics have label job equal to "prometheus".

Correct output would be empty results. 

So it's not working properly.
