There is already alot of discution about which logging framework is best for .Net.

Log4Net
EnterpriseLibrary
NLog
...

My question is if there is a product to manage a centralized repository of logs.

Imagine I choose any of the above logging frameworks and point several applications logs to a central server. What I'm looking for a server product that helps visualize and manage those logs. Preferably with a web interface.

Is there such a product?
