Next, download AWStats, which as of press time is in version 6.4.Īuthor’s Note: Be aware that earlier AWStats versions have known security problems, so if you’re already running AWStats and haven’t updated to the latest version, do so immediately. During the installation process, you have the option of installing an ISAPI Perl extension, but I recommend not installing it, as you don’t need it to run AWStats in offline mode However, if you do want to run AWStats (or other Perl scripts) online, go ahead and install it. ActivePerl 5.8 installs using a standard MSI installation. I recommend ActivePerl 5.8, which you can download from for free. To install AWStats on Windows, download a Perl interpreter (if you don’t already have one) and the AWStats software (scripts). Code referenced in this article is available for download. This article also looks at how to install AWStats, analyze logs, and publish generated reports from IIS 6 log files. For example, report generation is scheduled in offline mode to run during off-peak hours. This article discusses how to install and use AWStats only in offline mode, which is preferable because it minimizes security risks and resource usage, so as to not undermine Web server performance. The second is “offline” mode, in which AWStats analyzes data and creates static reports as HTML pages publishable via any standard Web server. When used in online mode, AWStats updates its reports on request. The first is interactive, or “online,” mode. The Perl source is neither very clear nor particularly readable, so it’s not easy to change the behavior of the software, but you can use it “as is” for most common needs.ĪWStats works in two modes. It requires an interpreter that can execute Perl scripts and has a small footprint on the server. In fact, most of the time, AWStats doesn’t consume any resources at all.ĪWStats is a Perl application with a simple structure. It is also very fast, and it doesn’t consume many resources. It can analyze a wide variety of logs, and it creates good reports - not the full-featured, interactive, and special-effect-filled reports costly commercial software generates - but still useful, with all the important data presented tastefully. If you can’t afford to devote an entire server to Web log analysis and report creation, then you need an inexpensive and fast solution that isn’t terribly resource-intensive.įortunately, such as solution exists, and its name is AWStats.ĪWStats is a free, open source log analyzer. For example, recent WebTrends (one of the more popular commercial packages) versions require considerable RAM and processor time. In addition, some log analyzers have a performance impact on the server itself. Unfortunately, most are also very expensive. Need to know what your Web site users are visiting in your sites? Try this free and open source Web log analyzer you can use with IIS6-hosted Web sites and applications.īecause log analysis is so important, many commercial software applications create useful and good-looking reports. Analyzing the logs reveals information about which resources are popular, what kinds of browsers people are using, how much bandwidth a Web site consumes, the request trend during a given time span, and so on. When logging is enabled, Web servers log information about each request. Web server logs are a powerful resource for extracting information about Web sites and applications.
