7### ShutdownAlarmMonitor
8
9This monitor will watch all instances of the
10`xyz.openbmc_project.Sensor.Threshold.HardShutdown` and
11`xyz.openbmc_project.Sensor.Threshold.SoftShutdown` D-Bus interfaces for the
12alarm properties to trip. When this happens, a configurable timer is started at
13the end of which a power off is executed if the alarms haven't reset by that
14time. Event logs will also be created.

16The configuration options `SHUTDOWN_ALARM_HARD_SHUTDOWN_DELAY_MS` and
17`SHUTDOWN_ALARM_SOFT_SHUTDOWN_DELAY_MS` can be used to change the delays.

25- `xyz.openbmc_project.Sensor.Threshold.Critical`
26- `xyz.openbmc_project.Sensor.Threshold.PerformanceLoss`
