xentrace - capture Xen trace buffer data
xentrace [ OPTIONS ] [ FILE ]
xentrace is used to capture trace buffer data from Xen. The data is
output in the following binary format (host endian):
CPU(uint) TSC(u64) EVENT(u32) D1 D2 D3 D4 D5 (all u32)
Where CPU is the processor number, TSC is the record's timestamp (the
value of the CPU cycle counter), EVENT is the event ID and D1...D5 are
the trace data.
Data is dumped onto the standard output (which must not be a TTY) or a
FILE specified on the command line.
The output should be parsed using the tool xentrace_format, which can
produce human-readable output in ASCII format.
Options
-t, --log-thresh=l
set the threshold number, l, of new records required to trigger
a write of all new records to the output
-s, --poll-sleep=p
set the time, p, (in milliseconds) to sleep between polling the
buffers for new data.
