From e0ee1ee96fa73ecbb3d9352736cad355cf4ad65b Mon Sep 17 00:00:00 2001 From: GrammaTonic Date: Mon, 2 Mar 2026 02:08:56 +0100 Subject: [PATCH] feat: add Phase 3 DORA metrics and job lifecycle tracking - Add native runner hook scripts (job-started.sh, job-completed.sh) using ACTIONS_RUNNER_HOOK_JOB_STARTED/COMPLETED env vars - CSV jobs.log format: timestamp,job_id,status,duration_seconds,queue_time_seconds - Rewrite metrics-collector.sh with histogram, queue time, cache stubs - Update entrypoints and all 3 Dockerfiles with hook integration - Replace Grafana overview dashboard with 24-panel DORA version - Add dora-metrics.json and job-analysis.json dashboards - Add integration test (33 assertions passing) - Add Phase 3 documentation and update plan Closes #1061 --- docker/Dockerfile | 6 + docker/Dockerfile.chrome | 6 + docker/Dockerfile.chrome-go | 6 + docker/entrypoint-chrome.sh | 12 + docker/entrypoint.sh | 12 + docker/job-completed.sh | 142 +++ docker/job-started.sh | 59 ++ docker/metrics-collector.sh | 172 +++- docs/features/PHASE3_DORA_METRICS.md | 213 ++++ .../grafana/dashboards/dora-metrics.json | 311 ++++++ .../grafana/dashboards/github-runner.json | 973 +++++++++++++++--- .../grafana/dashboards/job-analysis.json | 396 +++++++ plan/feature-prometheus-monitoring-1.md | 44 +- tests/integration/test-job-lifecycle.sh | 373 +++++++ 14 files changed, 2548 insertions(+), 177 deletions(-) create mode 100755 docker/job-completed.sh create mode 100755 docker/job-started.sh create mode 100644 docs/features/PHASE3_DORA_METRICS.md create mode 100644 monitoring/grafana/dashboards/dora-metrics.json create mode 100644 monitoring/grafana/dashboards/job-analysis.json create mode 100755 tests/integration/test-job-lifecycle.sh diff --git a/docker/Dockerfile b/docker/Dockerfile index fff2108f..a2fe0fb7 100644 --- a/docker/Dockerfile +++ b/docker/Dockerfile @@ -169,6 +169,12 @@ COPY --chown=runner:runner metrics-server.sh /usr/local/bin/metrics-server.sh COPY --chown=runner:runner metrics-collector.sh /usr/local/bin/metrics-collector.sh RUN chmod +x /usr/local/bin/metrics-server.sh /usr/local/bin/metrics-collector.sh +# Copy job lifecycle hook scripts (Phase 3: DORA Metrics) +# TASK-028: Runner calls these via ACTIONS_RUNNER_HOOK_JOB_STARTED/COMPLETED +COPY --chown=runner:runner job-started.sh /usr/local/bin/job-started.sh +COPY --chown=runner:runner job-completed.sh /usr/local/bin/job-completed.sh +RUN chmod +x /usr/local/bin/job-started.sh /usr/local/bin/job-completed.sh + # Final image runs as unprivileged runner user.
