Log Analyzer

Read a target log file, isolate important severity lines, group similar messages, and emit a Markdown summary.

Workflow

1. Confirm the input log path. 2. Run index.js with --input and optional --out . 3. Review the grouped output for dominant error families. 4. Use the report as a triage artifact, not as the only source of truth.

Output

Always include:

total scanned lines

WARN / ERROR / CRITICAL counts

grouped issue buckets

sample lines

suggested first checks
