Is System Center Operations Manager in your future?
SCOM 2007 R2 Provides Historical Data and Actionable UI Based on Selected SQL Instance

SQL Server DC and MDW Provides Detailed Context
Click on SQL Server CPU line to see
queriesObvious query causing the
CPU problem
Click on big stuff to see query details
Click on the big stuff again to see
query plan details
Query optimizer recommends a missing index so click on View
Plan link
Plan UI shows missing index with expected impact
Missing Index Details command loads
index statement in editor for DBA to
decide
Use parameter substitution UI to name the index, remove
the comments, run the command and the problem is
solved
SCOM Now Shows Health StateIndex
created here
Expected range before ending
workload
MDW Power Comes at a Cost
MDW grows around 250GB to 600 GB per day per instance collected compared to Ops
Manager DB which has collects much less data
How to Optimize Data Collection?
• Run MDW Wizard against SCOM instance• Configure DC for Query Stats and Server
Activity via API pointing to MDW on SCOM, but don’t enable collection
Host MDW on SCOM
• Try tools like Activity Monitor to solve problem
• Query DMVs if necessaryTry SSMS tools 1st
• If the problem lingers, enable the DC for instance
• Troubleshoot the problem• Disable the DC when finished
Enable DC as needed

Just in case you didn’t askAKA FAQ
Can you run the reports using SSRS? Why doesn’t this work with SQL Server 2005? How do I uninstall the Data Collector? How many servers can a single MDW handle? How come I can’t start the Utility Information
collection set? How come you didn’t talk about the Utility Control
Point?
