trac3r00 Log Analyzer
A 50,000-line log is not a report. This is.
Commands
python3 scripts/log_analyzer.py app.log
python3 scripts/log_analyzer.py app.log --level ERROR --top 10
python3 scripts/log_analyzer.py app.log --budget-errors 0 # CI: fail on any
python3 scripts/log_analyzer.py app.log --max-patterns 5 # CI: error diversity cap
python3 scripts/log_analyzer.py daemon.log --json
What it reports
- Total lines, error count, warning count, distinct pattern count
- Ranked patterns with occurrence counts and one verbatim example each
Volatile tokens (timestamps, UUIDs, hex, IPs, host:port, paths, numbers) are
normalized to <tokens> so the same failure from different hosts/times
groups into one pattern. Exception-style lines (FooError:, Traceback,
FAILED) count as errors even without an ERROR level token.
Exit codes
0 = no errors / within budget, 1 = errors found or over budget, 2 = input error.
Pairs with
systematic-debugging (what to do with the top pattern once you have it),
diff-review (the diff-level gate upstream of the runtime log).
