Preliminary
Description
The Event Sensor Type field indicates what types of
events the sensor is monitoring. E.g. temperature,
voltage, fan, etc.
The Event Type indicates what type of transition/state
change triggered the trap.
The Event Offset indicates which particular event
occurred for a given Even Type.
The Event Source Type describes the originator of the
event. It is ASF1.0(68h) for all PET frames defined by
this specification.
The Sensor Device is the SMBus address of the sensor
that caused the event for the PET frame.
The Sensor Number is used to identify a given instance of
a sensor relative to the Sensor Device.
The Entity ID indicates the platform entity the event is
associated with. E.g. processor, system board, etc.
The Entity Instance indicates which instance of the Entity
the event is for. E.g. processor 1 or processor 2.
The Event Status Index identifies a unique event
monitored by the ASF-sensor. It is zero-based, sequential,
continuous, and ranging form 0-37h.
The Event Status indicates the event state of the ASF-
sensor device associated with the message’s Event Status
Index.
The Event Severity gives the management station an
indication of the severity of the event in the PET frame.
Typical values are Monitor (0x01), Non Critical (0x08),
or Critical Condition (0x10).
