What is SCOM/MOM?
Microsoft System Center Operations Manager 2007 (OpsMgr) is a monitoring and operations management system, implemented using one or more computers that perform their assigned roles as components of a management group. The components cooperate over several secure communication channels to achieve management information work-flow and present information to operators and administrators. The most important data collected is the health of the managed objects; this health status is arrived at via models that affect the tactical placement of software probes called monitors.
