trace-cmd

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

NAME

       trace-cmd - interacts with Ftrace Linux kernel internal tracer

SYNOPSIS

       trace-cmd COMMAND [OPTIONS]

DESCRIPTION

       The trace-cmd(1) command interacts with the Ftrace tracer that is built inside the Linux kernel. It interfaces with the Ftrace specific
       files found in the debugfs file system under the tracing directory. A COMMAND must be specified to tell trace-cmd what to do.

COMMANDS

	   record  - record a live trace and write a trace.dat file to the
		     local disk or to the network.

	   report  - reads a trace.dat file and converts the binary data to a
		     ASCII text readable format.

	   hist    - show a histogram of the events.

	   options - list the plugin options that are available to *report*

	   start   - start the tracing without recording to a trace.dat file.

	   stop    - stop tracing (only disables recording, overhead of tracer
		     is still in effect)

	   extract - extract the data from the kernel buffer and create a trace.dat
		     file.

	   reset   - disables all tracing and gives back the system performance.
		     (clears all data from the kernel buffers)

	   split   - splits a trace.dat file into smaller files.

	   list    - list the available plugins or events that can be recorded.

	   listen  - open up a port to listen for remote tracing connections.

	   restore - restore the data files of a crashed run of trace-cmd record

	   stack   - run and display the stack tracer

	   check-events - parse format strings for all trace events and return
			  whether all formats are parseable

OPTIONS

       -h, --help
	   Display the help text.

       Other options see the man page for the corresponding command.
