Description Simon Pasquier 2022-04-07 09:40:11 UTC 
periodic-ci-openshift-release-master-ci-4.11-e2e-azure-techpreview-serial

is failing frequently in CI, see:
https://testgrid.k8s.io/redhat-openshift-ocp-release-4.11-informing#periodic-ci-openshift-release-master-ci-4.11-e2e-azure-techpreview-serial

Lots of techpreview 4.11 jobs have started to fail on "[sig-instrumentation][Late] Alerts shouldn't exceed the 500 series limit of total series sent via telemetry from each cluster [Skipped:Disconnected] [Suite:openshift/conformance/parallel]".

For example, https://prow.ci.openshift.org/view/gs/origin-ci-test/pr-logs/pull/openshift_cluster-capi-operator/46/pull-ci-openshift-cluster-capi-operator-main-e2e-aws-capi-techpreview/1511259398029185024. 

Snippet from the job log:

{  fail [github.com/openshift/origin/test/extended/prometheus/prometheus.go:497]: Unexpected error:
    <errors.aggregate | len:1, cap:1>: [
        {
            s: "promQL query returned unexpected results:\navg_over_time(cluster:telemetry_selected_series:count[34m51s]) >= 600\n[\n  {\n    \"metric\": {\n      \"prometheus\": \"openshift-monitoring/k8s\"\n    },\n    \"value\": [\n      1649152361.962,\n      \"606.5857142857142\"\n    ]\n  }\n]",
        },
    ]
    promQL query returned unexpected results:
    avg_over_time(cluster:telemetry_selected_series:count[34m51s]) >= 600
    [
      {
        "metric": {
          "prometheus": "openshift-monitoring/k8s"
        },
        "value": [
          1649152361.962,
          "606.5857142857142"
        ]
      }
    ]
occurred}

The test threshold is hardcoded at 600 series, we should revise the value given that more telemetry metrics are getting added over time.

the threshold on the number of telemetry series is changed to 650
openshift-tests.[sig-instrumentation][Late] Alerts shouldn't exceed the 650 series limit of total series sent via telemetry from each cluster [Suite:openshift/conformance/parallel]

no failed case for the series limit of total series so far
