AWStats – log analyzer

AWStats is short for Advanced Web Statistics. AWStats is powerful log analyzer which creates advanced web, ftp, mail and streaming server statistics reports based on the rich data contained in server logs. Data is graphically presented in easy to read web pages.

Designed with flexibility in mind, AWStats can be run through a web browser CGI (common gateway interface) or directly from the operating system command line.

Through the use of intermediary data base files, AWStats is able to quickly process large log files, as often desired.

With support for both standard and custom log format definitions, AWStats can analyze log files from Apache (NCSA combined/XLF/ELF or common/CLF log format), Microsoft’s IIS (W3C log format), WebStar and most web, proxy, wap and streaming media servers as well as ftp and mail server logs.
