hi all,
I found xentrace will lost record if there are too many=A0 event to trace.
But every event is important to me, so I want to trace all of them, not lost one.
what=A0 could I do to achieve this goal =3F

If it need to modify the source code of xentrace, I will do it. But will anyone give me some instructions=3F

xentrace --trace-buf-size=3D$NUM where $NUM defaults to 32.=A0 Try making it larger and see whether that helps.
