The standard log analysis tool provided by my hoster shows very limited information (trying to force me to buy a full fledged analysis package). I have downloaded the log files and would like to evaluate them locally on my PC (Windows or Linux). Any tips? I could only find web-based analysis programs that run on the server.
There are a number of log analysis packages that can be used. Some of the server based log analysis tools can be installed and run on your local machine to simulate a server. SmarterStats, AWStats, and WebTrends are a few good examples (although I'm not sure if WebTrends has a free version).
Steve Schofield (Windows Server MVP for IIS) lists a few examples on his blog.
The best “Log file analyser” is yourself. An analyzer might not see everything. Reading the log yourself is better than using an application.
