NAME

6       xentrace_format - pretty-print Xen trace data
7

SYNOPSIS

9       xentrace_format [ DEFS-FILE ]
10

DESCRIPTION

12       xentrace_format parses trace data in xentrace binary format from
13       standard input and reformats it according to the rules in a file of
14       definitions (DEFS-FILE), printing to standard output.
15
16       The rules in DEFS-FILE should have the format shown below:
17
18       event_id whitespace format
19
20       Each rule should start on a new line.
21
22       The format string may include format specifiers, such as: %(cpu)d,
23       %(tsc)d, %(event)d, %(1)d, %(2)d, %(3)d, %(4)d, %(5)d
24
25       [ the `d' format specifier output in decimal, alternatively `x'
26         will output in hexadecimal and `o' will output in octal ]
27
28       These correspond to the CPU number, event ID, timestamp counter and the
29       5 data fields from the trace record.  There should be one such rule for
30       each type of event to be pretty-printed (events which do not have
31       formatting rules are ignored).
32
33       A sample format file for Xen's predefined trace events is available in
34       the file tools/xentrace/formats in the Xen source tree.
35
36       Depending on your system and the rate at which trace data is produced,
37       this script may not be able to keep up with the output of xentrace if
38       it is piped directly.  In these circumstances you should have xentrace
39       output to a file for processing off-line.
