Pawel, are you aware of any changes that would have resulted in the updated queries you provided in https://github.com/openshift/console/pull/8800 to stop working?  I do not believe anything has changed on the console side that would have resulted in this new bug.

Comment 3 Robb Hamilton 2021-07-13 12:31:25 UTC

Reassigning to the monitoring team for investigation as it appears Pawel is on PTO and I need another monitoring team member to determine if there were monitoring changes that would have resulted in the updated queries Pawel provided in https://github.com/openshift/console/pull/8800 to stop working.

Comment 4 Simon Pasquier 2021-07-23 08:58:38 UTC

"instance:node_network_receive_bytes_excluding_lo:rate1m" has been renamed to "instance:node_network_receive_bytes_excluding_lo:rate5m" in https://github.com/openshift/cluster-monitoring-operator/pull/1214/files#diff-a94cb3a05102915974e53760083acd2687daeb37b792c060d2ded1912baab004 because of a change in the upstream node_exporter mixin.
We should probably improve kube-prometheus upstream to adjust the rate interval value based on the chosen scrape interval.

checked with 4.9.0-0.nightly-2021-07-25-125326, Network transfer query returns correct usage data, see the picture
