The Active Directory Domain Services Management Pack for System Center provides both proactive and reactive monitoring of your Active Directory deployment. It monitors events that various Active Directory components and subsystems place in the Application, System, and Service event logs. It also monitors the overall health of the Active Directory system and provides alerts for critical performance issues. The monitoring that this management pack provides includes monitoring of domain controllers and monitoring of health from the perspective of clients that use Active Directory resources. To monitor domain controllers, ADMP provides a predefined, ready-to-run set of processing rules, monitoring scripts, and reports that are designed specifically to monitor the performance and availability of domain controllers.
