32 .Nd analyze a trace stream
41 utility is used to analyze an event trace stream.
42 It takes a few global options, after which the user should
43 specify a subcommand, followed by the subcommands options.
45 The global options are
46 .Bl -tag -width indent
48 Specifies the file containing the event stream.
51 .Bl -ohang -width indent
54 Lists the individual events, one per line.
55 The flags it accepts are:
56 .Bl -tag -width indent-two
58 Limits the displayed events to those matching
63 Generates an svg file (by default "output.svg") in the current directory,
64 displaying the stream events.
65 The flags it accepts are:
66 .Bl -tag -width indent-two
68 Limits the displayed events to those occurring within the
69 specified time interval.
70 The interval is specified in the form [c|m]<num>:<num>.
73 starts with 'c', <num> is absolute (i.e. not relative to the start of the
74 event stream) clock cycles (integral).
77 starts with 'm', <num> is a floating point number specifying miliseconds
78 since the first event in the stream.
80 Specifies an alternate output file.
84 Displays summary information about the event stream.
