Check if the Host CPU has Halted Unexpectedly

The following steps describe how to check if the Host has halted due an operating system crash (“blue screen”) or other cause.

1. Retrieve the instance of CIM_Watchdog, where the “DeviceID” key equals “Watchdog 0”.

2. Examine TimeOfLastExpiration. If the value is "1111-11-11T11:11:11Z", then the watchdog expired. Perform processing done for a detected processor halt. If the value is ‘0000-00-00T00:00:00Z”, then the OS has loaded.

$watchdogRef = $wsmanConnectionObject.NewReference("SELECT * FROM CIM_Watchdog WHERE DeviceID='Watchdog 0'")

$watchdogInstance = $watchdogRef.Get()

$timeOfLastExpiration = $watchdogInstance.GetProperty("TimeOfLastExpiration")

$fwVersion = GetCoreVersion

if($fwVersion.ToString() -ge "5.1")

{

$timeOfLastExpiration = $timeOfLastExpiration.InternalObject.Text

}
