If you are a DBA, these are pretty much money. I have seen some many custom implementations and DBA’s trying to get reports like this, and if you have SQL Server 2005 SP2, you can download that and run a SQL script and then you have these reports. They give you insight into pretty much everything going on with your server. Why pay $1000’s for a product that will give you the same info when it is built right into SQL Server!!
