# Web server log analyzer

Drop or paste Apache, Nginx, IIS W3C, or JSON access logs and get status, path, client, and byte summaries, p50, p95, and p99 latency, a timeline, and flagged suspicious patterns.

Add a log and press Analyse. The sample log exercises every section on safe fake data.

Findings here are surfaced for triage, not declared an attack: a pattern matched the request line, and the report says so when such a request actually returned 2xx. A clean result only means nothing on the pattern list appeared in the logs you loaded. It says nothing about the traffic that was never logged, and scanning your own logs never sends a packet to the addresses inside them.
