CI E2e Debug

CI E2E Debug Skill

Download test log artifacts from a GitHub Actions CI run and inspect them for errors.

Steps

1. Find the artifact: Use gh api to list artifacts for the given CI run:

   gh api repos/apache/skywalking/actions/runs/<RUN_ID>/artifacts --jq '.artifacts[] | {id: .id, name: .name}'
   

2. Download and extract: Download the artifact zip and extract it:

   cd /tmp && rm -rf e2e-debug-logs && mkdir e2e-debug-logs && cd e2e-debug-logs
   gh api repos/apache/skywalking/actions/artifacts/<ARTIFACT_ID>/zip > artifact.zip
   unzip -o artifact.zip
   

3. Inspect OAP logs: Look for errors in the OAP server logs:

   # Find OAP log files
   find /tmp/e2e-debug-logs -name "skywalking-oap-*.log" -o -name "oap.log"
   # Check for errors
   grep -E "ERROR|Exception|FATAL|CannotCompileException" <log_file> | head -30
   

4. Inspect other component logs: Check BanyanDB, UI, and other pod logs as needed.

5. Report findings: Summarize the root cause error from the logs.

Notes

• CI artifacts are automatically uploaded by the e2e test framework to $SW_INFRA_E2E_LOG_DIR
• Log files are organized by namespace/pod name
• OAP init pods may have different errors than the main OAP pod — check all of them
• Common errors: MAL/LAL/OAL compilation failures, storage connection issues, module initialization errors
• Profile exporter tests (e.g., Trace Profiling ES): the exporter runs as a separate process with MockCoreModuleProvider. If a new service is added to CoreModule.services() but not registered in the mock, the exporter fails at startup with requiredCheck() error — but the OAP logs will show no errors (OAP is fine, the exporter subprocess is what fails). Check the test step that runs profile_exporter.sh.
• When OAP logs are clean but tests fail: look at which specific test step failed. Some e2e tests invoke standalone tools (profile exporter, data generator) that boot with mock providers and may fail independently of OAP.
