Advanced Web Statistics (AWStats) is a free powerful Web server logfile analyzer (Perl script) that shows you all your Web statistics including visits, unique visitors, pages, hits, rush hours, search engines, keywords used to find your site, robots, broken links, and more. It works with both IIS 5.0+ and Apache Web server log files as a CGI and/or from the command line. It also supports around 40 languages.
Performance Co-Pilot (PCP) is a framework and set of services for supporting system-level performance monitoring and performance management. It provides a unifying abstraction for all of the interesting performance data in a system, and allows client applications to easily retrieve and process any subset of that data using a single API. A client-server architecture allows multiple clients to monitor the same host, and a single client to monitor multiple hosts. Archive logging and replay are integrated so that a client application can use the same API to process real-time data from a host or historical data from an archive.
phpOpenTracker is a framework solution for the analysis of Web site traffic and visitor behaviour. It features a logging engine that, either invoked as a Web bug by an HTML image tag or embedded with two lines of code into your PHP application, logs each request to a Web site into a database. One installation can track an arbitrary number of Web sites. Through its API, you can easily access the gathered data and perform complex operations on it (for instance, the analysis of your visitors' click paths).
Fido is a multi-threaded file watcher which searches files in real time for user-defined patterns. When it locates a match, it runs a user-defined program. It is useful for monitoring log files for issues and responding to them. It was designed to recognize log file rotation and start monitoring from the beginning of the new file.
The Logfile Navigator, lnav for short, is a curses-based tool for viewing and analyzing log files. The value added by lnav over text viewers or editors is that it takes advantage of any semantic information that can be gleaned from the log file, such as timestamps and log levels. Using this extra semantic information, lnav can do things like interleaving messages from different files, generate histograms of messages over time, and provide hotkeys for navigating through the file. These features are meant to allow the user to quickly and efficiently focus on problems.
phpMyVisites is a Web traffic analyzer with very detailed reports and advanced graphics. It is not an Apache log analysis tool. phpMyVisites creates its own logs, and it allows access to more complete statistics. phpMyVisites provides information about visitors, page views, visitor follow-ups, countries of origin, software configurations, referrers, and much more. It also includes a powerful administration and configuration tool.
Geolizer is a patch for Webalizer that uses the GeoIP library to generate faster and more reliable geographic statistics than the default DNS suffix method. It is recommended that DNS reversal be disabled on your HTTP server for improved performance and more accurate statistics. It also supports country flag pictures, can be compiled under MinGW/MSYS, and features a human-readable transfer size display.
Report Magic is an add-on for Analog, a Web site logfile analysis program. Generated reports include a description with tabulated, graphed, and summarized results. All colors, fonts, and background images are completely customizable to help make resulting reports fit the theme of your Web site. Report Magic has translations for several languages. It runs on any platform that will run Perl and pre-compiled versions are available for Win32 and Mac.
