PROGRAM:

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.

stat - show tracing (ftrace) status of the running system

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)

restart - restart tracing from a previous stop (only effects recording)

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

whether all formats are parseable
