@TheRealJon I suspect the admin console has the same issue

@spadgett Yeah, I basically copied this query from dev console, so it's probably affecting us too. Should we open a separate PR for this, or just go ahead and have @vikram-raj update our query in this PR?

[vikram-raj]

@TheRealJon I will update that query in this PR.

[vikram-raj]

@TheRealJon @spadgett Updated the query in the admin console as well.

What are the pre-conditions for this?

I started a cluster with launch openshift/console#9358, created a Pod which consumes some CPU but could not see any datapoints for sum_irate -- sum_rate still works.

Cluster was based on 4.8.0-0.ci.test-2021-06-29-215834. Is a 4.9 cluster required for this change?

@jerolimov This change is in 4.9. Up to 4.8 sum_rate works as expected.

Thanks @vikram-raj

Verified it now on 4.9.0-0.nightly-2021-06-29-114024
