EventTrace class
An abstract class from which all event trace classes are derived.
The following syntax is simplified from MOF code.
[abstract]
class EventTrace
{
uint16 EventSize;
uint16 ReservedHeaderField;
uint8 EventType;
uint8 TraceLevel;
uint16 TraceVersion;
uint64 ThreadId;
uint64 TimeStamp;
uint8 EventGuid[];
uint32 KernelTime;
uint32 UserTime;
uint32 InstanceId;
uint8 ParentGuid[];
uint32 ParentInstanceId;
uint32 MofData;
uint32 MofLength;
};
The EventTrace class has these types of members:
