# Log File Parser

> Parse Apache, Nginx or JSON log lines into a sortable table with traffic summaries.

A log parser turns raw access-log lines into a sortable table. It recognises the Apache and Nginx combined format plus JSON-per-line, extracts the client IP, timestamp, method, path, status and byte count, then summarises traffic by status code, path, client or method with an error rate.

## FAQ

### What should I look for first in an access log?

The error rate and which paths produce it. A cluster of 404s on one path usually means a broken link; a cluster of 500s means a bug; a single IP generating thousands of requests means a scraper or an attack.
