APM .NET Object Discovery

Microsoft.SystemCenter.Apm.Infrastructure.Monitoring.ManagementServer.APMConfigInfra.Monitor (UnitMonitor)

This monitor verifies that the Management Server has successfully created objects that are needed for APM monitoring. The monitor turns to a warning state when a failure occurs during APM objects discovery, as this will prevent configuration from being distributed to agents. The monitor resets to Healthy when object discovery succeeds.

Knowledge Base article:

Summary

The instance state becomes unhealthy when the APM .NET objects that are required for configuration can’t be written by the Management Server.

Causes

APM configuration infrastructure creates object instances that are required for configuration of the APM .NET monitoring agents, based on the settings specified in the .NET Application Performance Monitoring template. During this process, there could be errors depending on server problems or conflicting settings, which will prevent the objects from being successfully discovered. The most common cause for this type of error is a configuration conflict is that the Internet Information Services management pack has been removed after APM had already been configured.

Resolutions

Check the Alert Context and the Operations Manager Event Log on the server to understand more about the exact type of conflict or error. The event log might contain multiple messages for a single conflict or error. They should be investigated. In case the IIS Management Pack has been removed, you would need to import it again. Several other errors might require escalation to Microsoft Technical Support.
