Access Log Analyzer Tool
I have started a new open source project providing a http-access-log-file analyzer. The tool is based on JEE6. You can use this web statistic tool to analyze a access-log file in more detail as with most other tools.
The analyzer works perfect with Glassfish 3.1. And it also provides a module to scan the Glassfish 3.1 access log file format.
See the project page for more deails: http://code.google.com/p/manik-web-stat/
If you have any suggestions please post them here.
