Web Log Analyzers?

sammy.lost-angel.com asks: "What's the best web log analyzer out there today? It's time to upgrade our horribly out of date one and I'm not sure what's good out there at this time. Our site receives about 50,000 hits a day, so things like remembering what's already been analyzed can save a lot of time." What about log analyzers that can work on more than one type of web server? An analyzer that could parse access data for, say, IIS and Apache would be a nice tool!

Re:What's it matter what server generates the logs

Last I checked, both IIS and Apache generate (or can be set to generate) W3C standard format logfiles. Part of the reason for having/using that standard is so that you don't get locked into a proprietary tool.

You might think so, but IIS breaks the standard in several ways. And it's not even really a standard, just an early working draft that was never finished.

In my opinion, a good logfile analysis tool should be able to recognise and analyse all commonly-used formats, and provide a means to specify custom formats. In other words, it should work with what the server has already produced, rather than force the server administrator to reconfigure the server and ignore old logfiles. My program analog does all this, but most programs don't.
