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.
