gathered information: https://cutt.ly/JjFYOy0 Customer is experiencing warnings and slowness for CLI operations since upgrading his cluster to 4.5 and then to 4.6. [root@loutcvnd5804 ~]# oc get nodes I0105 20:24:55.202503 9163 request.go:645] Throttling request took 1.11883936s, request: GET:https://console-openshift-console.apps.eng.openshift.tcc.etn.com:6443/apis/logging.openshift.io/v1?timeout=32s oc get crd -o name | wc -l ==> 173 CRDs I know that tere is several bugzilla raised about this issue and that those messages are triggered when the a number of CRD threshold is reached. 4.5: create 100 CRDs in 100 groups, oc get on any of the CRDs gets throttling messages 4.7: create 100 CRDs in 100 groups, oc get succeeds, no throttling 4.7: create 200 CRDs in 200 groups, oc get on any of the CRDs gets throttling messages ------------------- 200 seems like a low threshold for clusters with any sort of history. is there a way to resolve those warnings and the slowness for CLI operations ? Is there a way to identify CRDs that are no longer needed ? Thanks for your help.
