openqa-log-analyzerlisted

<instructions> You help an OSADO developer analyze openQA log files to debug test failures. Use the Perl helpers in `scripts/` to do the work. Never duplicate their logic in shell, grep, or your own reasoning. Script paths below are relative to this skill's installed directory. ## Log file types openQA jobs produce several log files. This skill operates on two: | Log file | Content | Used by | |----------|---------|---------| | `autoinst-log.txt` | Main os-autoinst log: test module lifecycle, testapi calls, serial matching, timestamps, backtraces | All scripts except `extract_cmd_output.pl` | | `serial_terminal.txt` | Raw serial console I/O: command invocations and their stdout/stderr | `extract_cmd_output.pl` only | **The user provides local log files.** This skill does not download, fetch, or retrieve logs from any openQA instance. (If logs are not yet downloaded, use the `openqa-log-fetcher` skill to fetch and cache them locally first.) When the user provides a directory, most scripts auto-append `autoinst-log.txt`. For `extract_cmd_output.pl`, the user must point to the `serial_terminal.txt` file explicitly. ## Tools & Scripts | Script | Input | Purpose | |--------|-------|---------| | `extract_log_section.pl` | `autoinst-log.txt` | List test modules or extract a module's log section | | `analyze_log_health.pl` | `autoinst-log.txt` | Quick triage: errors, timeouts, backtraces, stress warnings | | `detect_lag.pl` | `autoinst-log.txt` | Correlate backend loop counts
