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.
