46 New Dynamic Management Views In SQL Server 2008 CTP6

Remember the 33 new DMVs in SQL Server 2008 post? I was just poking around in SQL Server 2008  CTP6 and wanted to know if there were any new Dynamic Management Views since CTP5. There are 13 new DMVs in CTP6 and there are a total of 45 new Dynamic Management Views compared to SQL server 2005. The list of them is below, I think their names make clear what the dmv is supposed to do (or at least I think I know)

If you want to find out what the names of all the new DMVs are by running a query on your SQL Server 2008 box and you don't have a linked server to a SQL Server 2005 box then don't worry I have prepared the query below for you.

SQL Server 2008: When Was The Server Last Started?

SQL Server 2008 has an additional column in the sys.dm_os_sys_info Dynamic Management View. The name of the column is sqlserver_start_time and it will be the time SQL Server was last restarted

SELECT sqlserver_start_time FROM sys.dm_os_sys_info

DMVStats (A SQL Server 2005 Dynamic Management View Performance Data Warehouse ) Released

Over the last year, Tom Davidson has been working on a tool called DMVstats with some of his CAT colleagues. DMVstats collects performance oriented DMVs into a data warehouse, and provides a methodology called 'Waits' and 'Queues' to identify and track down performance issues. Drill-through analysis is provided by reporting services reports.



DMVStats 1.01
A SQL Server 2005 Dynamic Management View Performance Data Warehouse

Introduction
Microsoft SQL Server 2005 provides Dynamic Management Views (DMVs) to expose valuable information that you can use for performance analysis. DMVstats 1.0 is an application that can collect, analyze and report on SQL Server 2005 DMV performance data. DMVstats does not support Microsoft SQL Server 2000 and earlier versions.

Main Components
The three main components of DMVstats are:
• DMV data collection
• DMV data warehouse repository
• Analysis and reporting.
Data collection is managed by SQL Agent jobs. The DMVstats data warehouse is called DMVstatsDB. Analysis and reporting is provided by means of Reporting Services reports.
