Hi xxia, This is most likely an issue with the console dashboard rendering logic. It may not support "auto interval period". Can you please get it verified by the console qe team? If "auto interval period" is not supported then I am happy to remove the auto option from the "period" variable. OK, moving to Management Console component. Sorry for the trouble. Andy could you please take a look on this issue and do a further triage if needed. Thanks > OK, moving to Management Console component. Sorry for the trouble.
xxia, thanks for the thorough testing!
I've opened https://github.com/openshift/console/pull/7823 which adds basic support for `$__auto_interval_*` variables by treating them as being the same as `$__interval`. Tested 4.7.0-0.nightly-2021-01-14-211319, the error is gone. Select Time Range of 6 hours, select Period of $__auto_interval_period, per the PR, it should be 12m. Look at the graph "api request duration by verb - 99th quantile", it should correspond to below query:
histogram_quantile(0.99, sum(rate(apiserver_request_duration_seconds_bucket{apiserver="kube-apiserver",subresource!="log",verb!~"WATCH|WATCHLIST|PROXY"}[12m])) by(verb,le))
In Prometheus UI, do this query with 720 resolutions, then compare Prometheus UI's graph, same as web console's. This proves the PR.
