-
Lots of workflows process this data.
In this scenario, the Monitoringhost.exe process may not work efficiently, and it may consume all the CPU resources. The issue slows the overall number of performance counters that can be collected.

More Information
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.
