6 trace-cmd-stop - stop the Ftrace Linux kernel tracer from writing to
7 the ring buffer.
8
10 trace-cmd stop [OPTIONS]
11
13 The trace-cmd(1) stop is a complement to trace-cmd-start(1). This will
14 disable Ftrace from writing to the ring buffer. This does not stop the
15 overhead that the tracing may incur. Only the updating of the ring
16 buffer is disabled, the Ftrace tracing may still be inducing overhead.
17
18 After stopping the trace, the trace-cmd-extract(1) may strip out the
19 data from the ring buffer and create a trace.dat file. The Ftrace
20 pseudo file system may also be examined.
21
22 To disable the tracing completely to remove the overhead it causes, use
23 trace-cmd-reset(1). But after a reset is performed, the data that has
24 been recorded is lost.
25
27 -B buffer-name
28 If the kernel supports multiple buffers, this will stop the trace
29 for only the given buffer. It does not affect any other buffer.
30 This may be used multiple times to specify different buffers. When
31 this option is used, the top level instance will not be stopped
32 unless -t is given.
33
34 -a
35 Stop the trace for all existing buffer instances. When this option
36 is used, the top level instance will not be stopped unless -t is
37 given.
38
39 -t
40 Stops the top level instance buffer. Without the -B or -a option
41 this is the same as the default. But if -B or -a is used, this is
42 required if the top level instance buffer should also be stopped.
