I have used many different queries of DMV/DMF over the past years to get various information for SQL Server OS. So I am going to start keeping a record of all the queries and try to explain their meaning and usage as I understand them.

There are many DMV/DMF and it is hard to remember them all, in SQL Server 2005 there were 12 categories (link), totaling 78 DMV/DMFs and in SQL Server 2008 there are 17 categories (link), totaling 117 DMV/DMFs. I will make sure to point out any differences between two as I run into them. These help make a DBA life easier by providing alot of the low level system information we didn’t have access to before.

This post will be catch all for all the pages I use for my queries references. I think everyone’s work should be referenced fully; so if I have forgotten to reference your work please let me know. Thanks.
