Evaluating Daily Checklist Against 1000 Servers using Policy Based Management
This document discusses using Policy Based Management (PBM) and Central Management Server (CMS) to automate and evaluate a daily SQL Server checklist. It recommends creating policies in PBM to validate checklist items like SQL Agent jobs succeeded and backups completed successfully. The policies can run on a schedule or when changes are detected. CMS allows applying policies or scripts to multiple servers grouped by environment. The presenter demonstrates importing policies into PBM and evaluating them to automatically check the daily checklist.

Editor's Notes
- #3 If you currently have a solution like Scom or Big Brother to monitor daily checklist then this session will not be for you.
- #15 Focus on facets because this determines your evaluation mode options.
- #25 A perfect example of something that cannot be evaluated with Policy Based Management is disk space on a mount point.
