sysadmin

Hi,

I am running about 10 asp.net websites on a hosted virtual server. The server runs Server 2008 - each website is backed by its own database running on SQL server 2008 on the same box.

Lately the box has seemed really slow. The only kind of discovery i could think of doing was looking in the task manager, where i can see w3wp and sqlserver.exe jumping to 40% cpu usage every 5-10 seconds.

What are the steps i can take to determine which of my websites is taking these resources and or what database is getting hit the most? I have of course ssms installed on the machine as well.

As you can tell, my sysadmin skills are very very limited - any help would be much appreciated.
