CIM Reference Guide

52 CIM_LogicalElement
The CIM_WatchDog class described in Table 3-14 represents a timer that is
implemented in the system hardware. The watchdog feature allows the
hardware to monitor the state of the operating system, BIOS, or a software
component installed on the system. If the monitored component fails to reset
the timer before its expiration, the hardware assumes that the system is in a
critical state and could reset the system. 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 rearming the timer before
expiration.

Property Description Data Type
MonitoredEntity Indicates the entity that is currently being
