34 -p::
35 --pid=::
38 --tid=::
41 -a::
42 --all-cpus::
43 Force system-wide collection. Scripts run without a <command>
44 normally use -a by default, while scripts run with a <command>
45 normally don't - this option allows the latter to be run in
46 system-wide mode.
48 -C::
49 --cpu=::
52 Ranges of CPUs are specified with -: 0-2.
55 -v::
56 --verbose::
61 -------------------------------
63 -t::
64 --tracer=::
65 Tracer to use when neither -G nor -F option is not
68 -F::
69 --funcs::
73 -D::
74 --delay::
77 -m::
78 --buffer-size::
79 Set the size of per-cpu tracing buffer, <size> is expected to
80 be a number with appended unit character - B/K/M/G.

96 argument. Like -T option, this can be used more than once to
100 --func-opts::
103 - call-graph - Display kernel stack trace for function tracer.
104 - irq-info - Display irq context info for function tracer.
106 -G::
107 --graph-funcs=::
114 -g::
115 --nograph-funcs=::
117 given function (or a glob pattern). Like -G option, this is useful
123 --graph-opts::
126 - nosleep-time - Measure on-CPU time only for function_graph tracer.
127 - noirqs - Ignore functions that happen inside interrupt.
128 - verbose - Show process names, PIDs, timestamps, etc.
129 - thresh=<n> - Setup trace duration threshold in microseconds.
130 - depth=<n> - Set max depth for function graph tracer to follow.
131 - tail - Print function name at the end.

137 -T::
138 --trace-funcs=::
142 -b::
143 --use-bpf::
147 -n::
148 --use-nsec::
149 Use nano-second instead of micro-second as a base unit of the histogram.
151 --bucket-range=::
152 Bucket range in ms or ns (according to -n/--use-nsec), default is log2() mode.
154 --min-latency=::
156 -n/--use-nsec).
158 --max-latency=::
160 -n/--use-nsec). The setting is ignored if the value results in more than

174 --notrace-funcs=::
175 Do not trace functions given by the argument. Like -T option, this
179 -G::

186 -g::
187 --nograph-funcs=::
189 Like -G option, this is useful for the function_graph tracer only and
194 -m::
195 --buffer-size::
196 Set the size of per-cpu tracing buffer, <size> is expected to
197 be a number with appended unit character - B/K/M/G.
199 -s::
200 --sort=::
204 --graph-opts::
207 - nosleep-time - Measure on-CPU time only for function_graph tracer.
208 - noirqs - Ignore functions that happen inside interrupt.
209 - thresh=<n> - Setup trace duration threshold in microseconds.
