11. Miscellaneous Events
The miscellaneous events section addresses sensors not easily grouped with other sensor types.
11.1 IPMI Watchdog
EPSD server systems support an IPMI watchdog timer, which can check to see whether the OS is still responsive. The timer is
disabled by default, and has to be enabled manually. It then requires an IPMI-aware utility in the operating system that will reset the
timer before it expires. If the timer does expire, the BMC can take action if it is configured to do so (reset, power down, power cycle,
or generate a critical interrupt).
