Class CIM_Watchdog
extends CIM_LogicalDevice

CIM_Watchdog is a timer that is implemented in the system hardware. It allows the hardware to monitor the state of the Operating System, BIOS, or a software component that is installed on the System. If the monitored component fails to re-arm the timer before its expiration, the hardware assumes that the System is in a critical state, and could reset the ComputerSystem. This feature can also be used as an application watchdog timer for a mission-critical application. In this case, the application would assume responsibility for re-arming the timer before expiration.

KeepAlive (uint32)

Method Qualifiers (KeepAlive)

Name	Data Type	Value
Description	string	A method to re-arm the timer. This method is used only if the MonitoredEntity is "Application". It returns 0 if successful, 1 if unsupported, and any other value if an error occurred. In a subclass, the set of possible return codes could be specified, using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' can also be specified in the subclass as a Values array qualifier.
