Operations Manager 2007 has various server roles. These server roles include root management server, management server, gateway server, and agent. These roles all contain a process that is known as MonitoringHost.exe. The MonitoringHost.exe process is what each server role uses to perform monitoring activities, such as executing a monitor or running a task. For example, when an agent subscribes to the event log to read events, it is the MonitoringHost.exe process that runs those activities.
