Data Protection Manager 2006:  This management pack is designed for monitoring DPM events, collecting component-specific performance counters in one central location, and raising alerts for operator intervention as necessary. By detecting, sending alerts, and automatically responding to critical events, this DPM MP helps indicate, correct, and prevent possible service outages or configuration problems, allowing you to proactively manage your Data Protection Manager environment and identify issues before they become critical.
