I'm looking for some recommended configurations for IIS (7.5) logging for a reasonably high-traffic web-farm? Currently generating approx 500MB uncompressed logs on each of 4 web servers daily.
ODBC logging? To SQL Server seems like a lot of overhead for log files... Maybe to an open source database of some sort?
Should I just keep using log files and something like Analog to summarise them for points of interest?
What about Splunk? Could this be helpful?
Any recommendations or war-stories from people running IIS in larger environments and how you handle request logging?
