+
+ The data hub protocol is used both by agents wishing to log
+ data and those wishing to be made aware of all information that
+ has been logged.
+
+ For more information please look at Intel Platform Innovation

+// Version, HeaderSize, RecordSize, DataRecordGuid, DataRecordClass
+//
+// The Data Hub driver is responcible for initializing:
+// LogTime and LogMonotonicCount.
