Apache log formats supported

Combined Log Format (most common)

The Apache Combined Log Format is the default for most Apache installations. It includes the referrer and user agent fields that are essential for SEO and bot analysis:

192.168.1.1 - - [06/Mar/2025:10:15:30 +0000] "GET /products/widget HTTP/1.1" 200 4523 "https://www.google.com/" "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)"

Each field in order:

Common Log Format

A simpler format without referrer and user agent:

192.168.1.1 - - [06/Mar/2025:10:15:30 +0000] "GET /products/widget HTTP/1.1" 200 4523

LogBeast auto-detects both formats. Combined is preferred because it includes user agent data essential for bot detection.

Auto-detection: just drag and drop

You don't need to specify the log format. LogBeast automatically detects whether your file uses Apache Combined, Apache Common, Nginx, IIS, CloudFront, or Cloudflare format. Just drop the file and analysis starts immediately.

LogBeast vs. other Apache log analyzers

Frequently asked questions

Which Apache log format should I use?

Combined Log Format. It includes referrer and user agent fields essential for bot detection, SEO analysis, and understanding traffic sources. If you're using Common format, switch to Combined in your Apache config.

How large can my log file be?

LogBeast handles 1M+ lines routinely. For very large files (10M+ lines), processing takes a few minutes depending on your hardware. For ongoing analysis of massive logs, consider rotating logs and analyzing weekly/monthly segments.

Can I analyze compressed log files?

Decompress .gz files first (gunzip access.log.gz). LogBeast reads plain text log files. Future versions may support direct .gz import.

Does LogBeast support custom Apache log formats?

LogBeast supports the standard Combined and Common formats. Most custom formats are close enough to auto-detect. Highly customized formats with non-standard field ordering may require conversion.

Is my Apache log data private?

100%. LogBeast processes everything in your browser. Your log files — containing IP addresses, URLs, and user agents — never leave your machine.
