The new functionality coming out with 2008 includes the Data Collector which feeds to the Performance Data Warehouse. I presented this topic at the SNESSUG Heroes Launch event. It's pretty slick functionality. I posted about it once before. A new article by Derek Comingore is available now over at SQL Mag. It's worth the read. The beauty of the new tool is the fact that it's not all that new. It's doing all this work using tools that we know and are comfortable with. This makes it very easy to implement and maintain. I agree with Mr. Comingore and I hope they expand the client to cover SQL Server 2000 and 2005.
