Picking [1] to dig into:

  : [sig-arch] events should not repeat pathologically	0s
    1 events happened too frequently

    event happened 33 times, something is wrong: ns/openshift-etcd-operator deployment/etcd-operator - reason/RequiredInstallerResourcesMissing secrets: etcd-all-certs-3

Finding the events:

  $ curl -s https://gcsweb-ci.apps.ci.l2s4.p1.openshiftapps.com/gcs/origin-ci-test/logs/release-openshift-origin-installer-e2e-aws-upgrade-4.7-to-4.8-to-4.9-to-4.10-ci/1469761023668916224/artifacts/e2e-aws-upgrade/events.json | jq -r '.items[] | select(.metadata.namespace == "openshift-etcd-operator" and .reason == "RequiredInstallerResourcesMissing" and .count > 10) | .metadata.creationTimestamp + " " + (.count | tostring) + " " + .reason + ": " + .message' | sort

  2021-12-11T23:23:44Z 28 RequiredInstallerResourcesMissing: configmaps: etcd-endpoints-6

So that's pretty early.  Fitting 20:44:35Z into the updates:

  $ curl -s https://gcsweb-ci.apps.ci.l2s4.p1.openshiftapps.com/gcs/origin-ci-test/logs/release-openshift-origin-installer-e2e-aws-upgrade-4.7-to-4.8-to-4.9-to-4.10-ci/1469761023668916224/artifacts/e2e-aws-upgrade/clusterversion.json | jq -r '.items[].status.history[] | .startedTime + " " + (.completionTime // "-") + " " + .state + " " + .version'
  2021-12-11T23:23:08Z - Partial 4.10.0-0.ci-2021-12-11-061053
  2021-12-11T21:56:22Z 2021-12-11T23:22:59Z Completed 4.9.0-0.nightly-2021-12-09-104153
  2021-12-11T20:43:47Z 2021-12-11T21:56:14Z Completed 4.8.24
  2021-12-11T20:15:58Z 2021-12-11T20:42:44Z Completed 4.7.39

So the hot missing-secret event was from shortly after the 4.7.39 to 4.8.24 leg began.  I dunno if this is an etcd issue, or something more on the Kube-core side, or what.  Might also be something that's more widespread in 4.7/4.8 updates, because only 4.9+ origin test suites care about it, which may be why we only notice in these longer update chains:

  origin$ git --no-pager grep 'repeat pathologically' origin/release-4.9
  origin/release-4.9:pkg/synthetictests/duplicated_events.go:     const testName = "[sig-arch] events should not repeat pathologically"
  origin$ git --no-pager grep 'repeat pathologically' origin/release-4.8
  ...no hits...

Assigning to Test Framework 4.9 about possibly relaxing the test coverage, but we could also assign to 4.7 or 4.9 components in charge of avoiding the RequiredInstallerResourcesMissing spew.
