Web Log Analyzer

If you have never used this program before, read below first.

Security Certificate

You may be prompted about a "Security Warning" and asked whether you want to accept my security certificate, which is not signed by a trusted authority. Whether you accept my certificate is up to you, but this program requires you to accept it in order to work - this program will both read and write from your local hard drive, in the manner explained below.

Instructions

This program is capable of analyzing log files in both Apache and W3C formats. When you are analyzing Apache log files, the Common Log Format (CLF) is assumed unless you specify a custom format using the syntax found in the Apache documentation (the screen shot shows an example custom format). Note you can also use the words "common" and "combined" as in the Apache documentation. When you are analyzing W3C format log files, the headers in the log files themselves contain all the required format information. The Apache Log format field will be ignored when processing W3C format logs. The program will automatically detect which type of log files are being analyzed.

You can pick individuals files to analyze, zip files containing log files (zip files must contain ONLY log files), directories containing only log files, or a combination of all three.

The program outputs a set of html and image files - saved to the output directory you specify. When the program is finished, just use your web browser to navigate to the ouput directory and load "index.html".

screen shot

One more thing - All the HTML generated by this program is XHTML 1.0 compliant. Adhering to the XHTML 1.0 specification makes it easier for browsers to parse the documents and makes it more likely that these pages will be rendered the same way in all browsers.

(This page is also XHTML 1.0 compliant.)
