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.

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.
