WalkthroughThe script now runs a Prometheus port-forward watchdog. The watchdog checks endpoint health, recreates failed port-forwards, tracks the current PID, and coordinates process cleanup during script exit. ChangesPrometheus port-forward lifecycle
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The change improves recovery of Prometheus connectivity during integration tests, but a restart can briefly race the old process releasing port 9090 and delay recovery by one polling cycle. The PR is mergeable with owner awareness or follow-up to wait for the old process to exit before rebinding. Sequence Diagram(s)sequenceDiagram

- Around line 401-409: Update the replacement logic around the old_pid kill and
new port-forward startup to wait until the previous oc port-forward process has
exited and released port 9090 before launching the replacement. Preserve the
existing cleanup and watchdog behavior, and avoid relying on the fixed
one-second sleep alone.

Summary
Add a background watchdog process that monitors the Prometheus port-forward health during OSDFM integration test runs and auto-restarts it if the connection drops.
Problem
The OSDFM integration tests (
ocm-fvt-gating-osdfm-integration-canary) useoc port-forwardto tunnel to the Prometheus instance on the appsre management cluster. The initial setup has retry logic (pf_max_retries=3), but once tests begin there is no mechanism to detect or recover from a dropped port-forward.When the PF drops mid-test, all 8
feature-alertsmetrics tests fail withcurl exit code 7(connection refused). The test-code retry layer (12 attempts) re-curls the dead connection but cannot restart the port-forward itself. This causes recurring transient failures in the canary integration job.Changes
New variables (script top-level):
pf_watchdog_pid— tracks the watchdog background processpf_pid_file— shared PID file so the watchdog can update the current PF PID across restartsUpdated
cleanup_ocm_fvt()trap handler:prom_pf_pidif no PID file exists (backward-compatible)Background watchdog subshell (inserted after initial PF readiness, before tests):
oc port-forwardcommand using the saved appsre kubeconfig, waits up to 30s for readiness[PF-WATCHDOG]prefix and timestamps for easy identification in CI logsTesting
