The Microsoft SQL Server Management Pack provides both proactive and reactive monitoring of SQL Server 2008, 2005 and SQL Server 2000 in an enterprise environment. Availability and configuration monitoring, performance data collection, and default thresholds are built for enterprise-level monitoring. Both local and remote connectivity checks help ensure database availability.
With the embedded expertise in the SQL Server Management Pack, you can proactively manage SQL Server, and identify issues before they become critical. This Management Pack increases the security, availability, and performance of your SQL Server infrastructure.
The Microsoft SQL Server Management Pack Guide that comes with the pack describes the content of the management pack, and describes how to deploy it.
