What is the best raw log interpretation software out there. Pay or free does'nt matter. Do any of you guys have a preference?

I forgot , my hosting company is using windows as their servers.

WebTrends would be first on my list. The reports are good and very well layed out. Wusage is another good one, but most hosting companies don't use it since it produces lots of static pages that takes up space. Webalizer is a good free one that generates the fewest amount of pages, hence most companies give their customers access to it.

I am currently writing some autoscripts for for ReportMagic - used together with Analog . This is a very nice solution:
free
fast ( both are exe:s, no slow perl scripts )
nice graphical interface ( ReportMagic gives you that )
