Nginx Log Parser

Parse nginx access log lines into structured fields. Supports combined and common log formats. Filter by status code range (2xx/3xx/4xx/5xx), search by path or IP. View statistics including top paths, top IPs, status breakdown, and total bytes. Runs entirely in your browser — your data never leaves your machine.

All interactive tools run entirely in your browser. Your data never leaves your device.

How It Works

Paste nginx access log lines and the tool parses each line into structured fields: IP address, method, path, protocol, status code, body bytes, referer, and user agent. Filter and search results interactively. View aggregate statistics.

Features

  • 2 log formats: combined and common log format
  • Status filtering: all, 2xx, 3xx, 4xx, 5xx
  • Path search: filter entries by URL path substring
  • IP search: filter entries by IP address
  • Statistics: total entries, status breakdown, unique IPs, unique paths, total bytes
  • Top paths: most requested URLs ranked by count
  • Top IPs: most active IP addresses ranked by count
  • Parse error reporting: invalid lines flagged with line numbers
  • 5 examples: mixed statuses, API traffic, static assets, common format, bot traffic
  • Private: all computation runs in your browser — no data transmitted

Use Cases

  • Analyzing nginx access logs during debugging
  • Finding most requested URLs and active IPs
  • Filtering error responses (4xx, 5xx) from large log files
  • Identifying bot traffic patterns
  • Quick log analysis without installing log parsing tools
