WHEA Hardware Error Events (Windows Vista)

In Windows Vista, the operating system sends WHEA hardware error events directly to the system event log. The GUID for the provider of these events is WHEA_ETW_PROVIDER. The name for the provider is Microsoft-Windows-Kernel-WHEA.

The following table describes each of the WHEA hardware error events that are defined for Windows Vista.

Event	Description
EVENT_WHEA_CORRECTED_ERROR	Generic corrected hardware error.
EVENT_WHEA_UNCORRECTED_ERROR	Generic uncorrected hardware error.
EVENT_WHEA_MEMHIERARCHY_ERROR	Memory hierarchy machine check exception.
EVENT_WHEA_MEMHIERARCHY_WARNING	Corrected memory hierarchy machine check.
EVENT_WHEA_TLB_ERROR	Translation lookaside buffer machine check exception.
EVENT_WHEA_TLB_WARNING	Corrected translation lookaside buffer machine check.
EVENT_WHEA_BUS_ERROR	Bus machine check exception.
EVENT_WHEA_BUS_WARNING	Corrected bus machine check.
EVENT_WHEA_BUSTO_ERROR	Bus timeout machine check exception.
EVENT_WHEA_BUSTO_WARNING	Corrected bus timeout machine check.
EVENT_WHEA_WDTO_ERROR	HyperTransport watchdog timeout machine check exception.
EVENT_WHEA_ROMPARITY_ERROR	ROM parity error machine check exception.
EVENT_WHEA_EXTERNAL_ERROR	Generic external machine check exception.
EVENT_WHEA_FRC_ERROR	Functional redundancy check machine check exception.
EVENT_WHEA_PCIE_ERROR	Uncorrected PCI Express error.
EVENT_WHEA_PCIE_WARNING	Corrected PCI Express error.

All of these hardware error events are recorded in the system event log.

Each of the WHEA hardware error events that are defined for Windows Vista has an associated event identifier. An application can determine which errors have occurred by examining the EventID system value that is associated with each WHEA hardware error event. Each WHEA hardware error event that is defined for Windows Vista uses one of three data templates to describe the hardware error data that is associated with the event. The following table lists the event identifier and the data template that is associated with each of the WHEA hardware error events that are defined for Windows Vista.

Event	Event ID	Data template
EVENT_WHEA_CORRECTED_ERROR	1	WHEARecord
EVENT_WHEA_UNCORRECTED_ERROR	2	WHEARecord
EVENT_WHEA_MEMHIERARCHY_ERROR	6	WHEAMachineCheck
EVENT_WHEA_MEMHIERARCHY_WARNING	7	WHEAMachineCheck
EVENT_WHEA_TLB_ERROR	8	WHEAMachineCheck
EVENT_WHEA_TLB_WARNING	9	WHEAMachineCheck
EVENT_WHEA_BUS_ERROR	10	WHEAMachineCheck
EVENT_WHEA_BUS_WARNING	11	WHEAMachineCheck
EVENT_WHEA_BUSTO_ERROR	12	WHEAMachineCheck
EVENT_WHEA_BUSTO_WARNING	13	WHEAMachineCheck
EVENT_WHEA_WDTO_ERROR	14	WHEAMachineCheck
EVENT_WHEA_ROMPARITY_ERROR	15	WHEAMachineCheck
EVENT_WHEA_EXTERNAL_ERROR	16	WHEAMachineCheck
EVENT_WHEA_FRC_ERROR	17	WHEAMachineCheck
