Visual Real-Time Apache Log Analyzer - GoAccess

GoAccess is an open source real-time Apache log analyzer and interactive viewer that runs in a terminal in *nix systems. It provides fast and valuable HTTP statistics for system administrators that require a visual server report on the fly.

Essentially, the way GoAccess works is that it will parse the well-known Apache access log file, from there, GoAccess will collect data from the parsed log and it will display it to the console or the X terminal. The collected information or generated reports will be displayed to the user/sysadmin in a visual/interactive window. Reports include:
 * General Statistics, bandwidth etc.
 * Top Visitors
 * Requested files
 * Requested static files, images, swf, js, etc.
 * Referrers URLs
 * 404 or Not Found
 * Operating Systems
 * Browsers and Spiders
 * Hosts, Reverse DNS, IP Location
 * HTTP Status Codes
 * Referring Sites
 * Keyphrases
 * Different Color Schemes
 * Unlimited log file size
Log format
GoAccess can parse both of Apaches' log formats, the Common Log Format (CLF) and the Combined Log Format (XLF/ELF), including virtual host. It is possible to parse Nginx as well. (if configured with the standard Apache log format)
