where to find TraceEvents output log file?

As I was reading driver code, I notice there is a lot of TraceEvents function call. For example:

if (!NT_SUCCESS (status)) {
TraceEvents(TRACE_LEVEL_ERROR, DBG_PNP,
“OsrFxSetPowerPolicy failed %!STATUS!\n”, status);
return status;
}

The outputs of TraceEvents function call will help debugging. My question is that where do I find the log file that contains those outputs?

Thanks
