TRACE-CMD-RESET(1)							       TRACE-CMD-RESET(1)

NAME
       trace-cmd-reset - turn off all Ftrace tracing to bring back full performance

SYNOPSIS
       trace-cmd reset [OPTIONS]

DESCRIPTION
       The trace-cmd(1) reset command turns off all tracing of Ftrace. This will bring back the
       performance of the system before tracing was enabled. This is necessary since
       trace-cmd-record(1), trace-cmd-stop(1) and trace-cmd-extract(1) do not disable the tracer,
       event after the data has been pulled from the buffers. The rational is that the user may
       want to manually enable the tracer with the Ftrace pseudo file system, or examine other
       parts of Ftrace to see what trace-cmd did. After the reset command happens, the data in
       the ring buffer, and the options that were used are all lost.

OPTIONS
       -b buffer_size
	   When the kernel boots, the Ftrace ring buffer is of a minimal size (3 pages per CPU).
	   The first time the tracer is used, the ring buffer size expands to what it was set for
	   (default 1.4 Megs per CPU).

	       If no more tracing is to be done, this option allows you to shrink the
	       ring buffer down to free up available memory.

	       trace-cmd reset -b 1
