TRACE-CMD-EXTRACT(1)		[FIXME: manual]		  TRACE-CMD-EXTRACT(1)

NAME
       trace-cmd-extract - extract out the data from the Ftrace Linux tracer.

SYNOPSIS
       trace-cmd extract [OPTIONS]

DESCRIPTION
       The trace-cmd(1) extract is usually used after trace-cmd-start(1) and
       trace-cmd-stop(1). It can be used after the Ftrace tracer has been
       started manually through the Ftrace pseudo file system.

       The extract command creates a trace.dat file that can be used by
       trace-cmd-report(1) to read from. It reads the kernel internal ring
       buffer to produce the trace.dat file.

OPTIONS
       -p plugin
	   Although extract does not start any traces, some of the plugins
	   require just reading the output in ASCII format. These are the
	   latency tracers, since the latency tracers have a separate internal
	   buffer. The plugin option is therefore only necessary for the
	   wakeup, wakeup-rt, irqsoff, preemptoff and preemptirqsoff plugins.

	       With out this option, the extract command will extract from the internal
	       Ftrace buffers.

       -O option
	   If a latency tracer is being extracted, and the -p option is used,
	   then there are some Ftrace options that can change the format. This
	   will update those options before extracting. To see the list of
	   options see trace-cmd-list. To enable an option, write its name, to
	   disable the option append the characters no to it. For example:
	   noprint-parent will disable the print-parent option that prints the
	   parent function in printing a function event.

       -o outputfile
	   By default, the extract command will create a trace.dat file. This
	   option will change where the file is written to.
