Tracing Events

Once a process' call to VT_initialize() has completed successfully it can start calling VT API functions that log events. These events will be associated with a time stamp generated by Intel® Trace Collector and with the thread that calls the function.

Should the need arise, then VT API functions could be provided that allow one thread to log events from several different sources instead of just itself.

Event types supported at the moment are those also provided in the normal Intel® Trace Collector, like state changes (VT_enter(), VT_leave()) and sending and receiving of data (VT_log_sendmsg(), VT_log_recvmsg()). The resulting trace file is in a format that can be loaded and analyzed with the standard Intel® Trace Analyzer tool.
