Managed Availability Failed by Design Error

If you navigate to the Exchange’s ProbeResult Crimson Channel under ActiveMonitoring, you will likely find the following error event logged:

EventID: 2
Channel: Microsoft-Exchange-ActiveMonitoring/ProbeResult
ResultId: 479968430
ServiceName: Monitoring
ResultName: HealthManagerHeartbeatProbe
Error:  Failed by design.
Exception: System.Exception: Failed by design. at Microsoft.Office.Datacenter.ActiveMonitoring.TestActiveMonitoringProbe.DoWork(CancellationToken cancellationToken) at Microsoft.Office.Datacenter.WorkerTaskFramework.WorkItem.Execute(CancellationToken joinedToken) at Microsoft.Office.Datacenter.WorkerTaskFramework.WorkItem. c__DisplayClass2.startexecuting b__0() at System.Threading.Tasks.Task.Execute()

So why is something failing by design?! Basically this probe is testing the Managed Availability framework, including that it can run responders. More specifically, a probe that will test that monitors can become unhealthy and execute null responders.

Bottom line, nothing to worry about :)
