Since the telemeter server side has not been synced yet, see https://bugzilla.redhat.com/show_bug.cgi?id=1799057#c5, holding verification. Verified with the following OCP env, $ oc version Client Version: v4.4.0 Server Version: 4.4.0-0.nightly-2020-02-18-132334 Kubernetes Version: v1.17.1 Verification steps, 1. Check if the code changes of PR https://github.com/openshift/cluster-kube-apiserver-operator/pull/737 in, $ oc get ServiceMonitor -n openshift-kube-apiserver -o yaml apiVersion: v1 items: - apiVersion: monitoring.coreos.com/v1 kind: ServiceMonitor ... relabelings: - action: replace replacement: kube-apiserver targetLabel: apiserver ... $ oc get PrometheusRule -n openshift-kube-apiserver -o yaml ... - name: apiserver-requests-in-flight rules: - expr: | max_over_time(sum(apiserver_current_inflight_requests{apiserver=~"openshift-apiserver|kube-apiserver"}) by (apiserver,requestKind)[2m:]) record: cluster:apiserver_current_inflight_requests:sum:max_over_time:2m ... $ oc -n openshift-monitoring get cm telemetry-config -oyaml | grep "cluster:apiserver_current_inflight_requests:sum:max_over_time:2m" # cluster:apiserver_current_inflight_requests:sum:max_over_time:2m gives maximum number of requests in flight - '{__name__="cluster:apiserver_current_inflight_requests:sum:max_over_time:2m"}' The code changes are checked as expected. 2. Check if the feature work fine with Metrics. Open the OCP cluster web console, on the left panel, navigate to Monitoring-> Metrics, enter the keyword ‘cluster:apiserver_current_inflight_requests:sum:max_over_time:2m’ in query textarea of displayed page , click on ‘Run Queries’, four items of openshift-apiserver and kube-apiserver are displayed, at column Value, we can see the requests number in 2 minutes. We will see the feature work as expected. Pasted the ‘cluster:apiserver_current_inflight_requests:sum:max_over_time:2m’ result in Prometheus,
Element Value
cluster:apiserver_current_inflight_requests:sum:max_over_time:2m{apiserver="kube-apiserver",requestKind="mutating"} 4
cluster:apiserver_current_inflight_requests:sum:max_over_time:2m{apiserver="kube-apiserver",requestKind="readOnly"} 6
cluster:apiserver_current_inflight_requests:sum:max_over_time:2m{apiserver="openshift-apiserver",requestKind="mutating"} 1
cluster:apiserver_current_inflight_requests:sum:max_over_time:2m{apiserver="openshift-apiserver",requestKind="readOnly"} 3
