trace-cmd-extract
TRACE-CMD-EXTRACT(1)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.
