TRACE-CMD-STOP(1)              libtracefs Manual             TRACE-CMD-STOP(1)

NAME
       trace-cmd-stop - stop the Ftrace Linux kernel tracer from writing to
       the ring buffer.

SYNOPSIS
       trace-cmd stop [OPTIONS]

DESCRIPTION
       The trace-cmd(1) stop is a complement to trace-cmd-start(1). This will
       disable Ftrace from writing to the ring buffer. This does not stop the
       overhead that the tracing may incur. Only the updating of the ring
       buffer is disabled, the Ftrace tracing may still be inducing overhead.

       After stopping the trace, the trace-cmd-extract(1) may strip out the
       data from the ring buffer and create a trace.dat file. The Ftrace
       pseudo file system may also be examined.

       To disable the tracing completely to remove the overhead it causes, use
       trace-cmd-reset(1). But after a reset is performed, the data that has
       been recorded is lost.

OPTIONS
       -B buffer-name
           If the kernel supports multiple buffers, this will stop the trace
           for only the given buffer. It does not affect any other buffer.
           This may be used multiple times to specify different buffers. When
           this option is used, the top level instance will not be stopped
           unless -t is given.

       -a
           Stop the trace for all existing buffer instances. When this option
           is used, the top level instance will not be stopped unless -t is
           given.

       -t
           Stops the top level instance buffer. Without the -B or -a option
           this is the same as the default. But if -B or -a is used, this is
           required if the top level instance buffer should also be stopped.
