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?
