I was playing with the moss 2010 and have found "Database driven Log system" as new feature. Now all the logs can store into a database from all the servers within a farm.
The only thing you have to do is turn on this feature in Central Admin.
You can see the following logs: ULS, events, performance counter, memory info, disk info, etc.
For more detail please go to microsoft's sharepoint site
Nthing I am going to do is to design the SSRS report for different log info, once those will be ready, I will post those reports for you guys.
Enjoy green coding...
