Microsoft.SystemCenter.ManagementConfigurationServiceGroup.AgentPoolAssignmentMonitor (UnitMonitor)

Monitor to get a state of the agent pool management work item on Management Configuration Service Group

Summary

The System Center Management Configuration Service has failed to perform the Agent Pool Assignment task within an acceptable amount of time.
