Comment 3 shahan 2019-12-02 05:46:12 UTC
It seems the console still using the wrong query on dashboard for memory/cpu/disk
(sum(node_filesystem_size_bytes) - sum(node_filesystem_free_bytes))[60m:5m]
 and get error on prometheus UI:
Error executing query: invalid expression type "range vector" for range query, must be Scalar or instant Vector
It is better to remove '[60m:5m]' to avoid confusing others. Or change url to "https://prometheus-k8s-openshift-monitoring.apps.***/graph?g0.range_input=1h&g0.expr=cluster%3Acpu_usage_cores%3Asum%5B60m%3A5m%5D&g0.tab=1"  with 'tab=1'


Comment 4 Rastislav Wagner 2019-12-02 15:41:08 UTC
@shahan the issue is that in 4.2 we are still using range selector for prometheus 'query' endpoint which results in an error when opening prometheus UI as you described. The queries are fixed however. If we need to switch to 'query_range' endpoint for 4.2 too than we should open a new bug and not reopen this one IMO.
