Platform Event Traps (PET) Events and Intel vPro

Intel AMT Remote Management provides always-available access to event logs of the following: PC Sensors, effectors, and other non-volatile data. It also has the ability to generate out-of-band alerts (PETs) based on sensor events.Platform Event Trap is a specification defining the format for managed systems to alert a remote console.

Knowledge of deciphering these Events comes in handy when trying to display the content of event logs from an Intel AMT system in a human readable format and from time to time we get questions on the Forum asking "how are we supposed to decipher these events??" In one such thread, the user actually took a lot of time to go through the IPMI specification and provided the community with a code snippet to help them decipher the events (pertaining to the AMT DTK code.)  (included below)

Anyone using the DTK who wishes to get a more detailed error message such as shown in the web interface can achieve this by modifying the AmtEventManager.cs file as shown below. 

public class AmtEventData
private static string[] SystemFirmwareError =
"No system memory is physically installed in the system.",
"No usable system memory, all installed memory has experienced an unrecoverable failure.",
"Unrecoverable hard-disk/ATAPI/IDE device failure.",
"Unrecoverable system-board failure.",
"Unrecoverable diskette subsystem failure.",
"Unrecoverable hard-disk controller failure.",
"Unrecoverable PS/2 or USB keyboard failure.",
"Removable boot media not found",
"Unrecoverable video controller failure",
"No video device detected",
"Firmware (BIOS) ROM corruption detected",
"CPU voltage mismatch processors that share same supply have mismatched voltage requirements)",
"CPU speed matching failure"
private static string[] m_SystemFirmwareProgress =

public static string GetEventDetailStr(byte eventSensorType, byte eventOffset, byte[] eventDataField)
if (15 != eventSensorType) return "Unknown Event Type";

if (0 == eventOffset) return SystemFirmwareError[eventDataField[1]];
else return m_SystemFirmwareProgress[eventDataField[1]];
catch (IndexOutOfRangeException)
return "Unknown Event Type";
public class AmtEvent
private EventLogRecordType evt
public string EventDetailStr{ get { return AmtEventData.GetEventDetailStr

(evt.EventSensorType, evt.EventOffset, evt.EventData); }
