OCPBUGS-111056: Make operator log scraper and monitor tests topology-aware - #31597
Conversation
…aware
The initial-and-final-operator-log-scraper monitor test hard-fails on TNF
(DualReplica) and SNO after disruptive recovery: node reboots race with
kube-apiserver/kubelet coming back up, producing 503s, kubelet proxy auth
errors, and terminated-container errors that the scraper treats as fatal.
Detect DualReplica/SingleReplica topology via the Infrastructure CR and
downgrade transient collection errors to FlakeError instead of a hard
failure, retrying Pods("").List() with exponential backoff first. Apply the
same topology-aware flake treatment to three other monitor tests that see
the same class of expected noise during reduced-topology recovery:
kubelet-log-collector's lease-error detector, legacy-node-invariants'
graceful-termination and overlapping-apiserver checks, and the pathological
events backoff-starting-failed-container check. HA behavior is unchanged —
these errors still hard-fail there.
Also tighten the scraper's pod name filter from Contains("operator") to
Contains("-operator-") to stop matching unrelated marketplace catalog pods
like redhat-operators-*.

…penshift#31597 Reverts the 4 monitor-test files to main's version so this PR is scoped to just the TNF recovery suite stability fixes, per review feedback on splitting the two independent concerns into separate PRs. The topology awareness work (operator-log-scraper + kubelet-log-collector + legacy-node-invariants + pathological events) now lives in openshift#31597.

Do not classify topology-discovery failures as HA.
A temporary Infrastructure read failure makes these paths treat an unknown topology as non-reduced. A DualReplica or SingleReplica run then hard-fails on recovery errors that this PR must classify as flakes.
