NAME

6       xentrace - capture Xen trace buffer data
7

SYNOPSIS

9       xentrace [ OPTIONS ] [ FILE ]
10

DESCRIPTION

12       xentrace  is  used  to capture trace buffer data from Xen.  The data is
13       output in the following binary format (host endian):
14
15           CPU(uint) TSC(u64) EVENT(u32) D1 D2 D3 D4 D5 (all u32)
16
17       Where CPU is the processor number, TSC is the record's  timestamp  (the
18       value  of the CPU cycle counter), EVENT is the event ID and D1...D5 are
19       the trace data.
20
21       Data is dumped onto the standard output (which must not be a TTY) or  a
22       FILE specified on the command line.
23
24       The  output  should be parsed using the tool xentrace_format, which can
25       produce human-readable output in ASCII format.

33
34       -s, --poll-sleep=p
35              set  the time, p, (in milliseconds) to sleep between polling the

54   Event Classes (Masks)
55       The following event classes (masks) can be used to  filter  the  events
56       being gathered by xentrace:
