NAME

6       trace-cmd - interacts with Ftrace Linux kernel internal tracer
7

SYNOPSIS

9       trace-cmd COMMAND [OPTIONS]
10

DESCRIPTION

12       The trace-cmd(1) command interacts with the Ftrace tracer that is built
13       inside the Linux kernel. It interfaces with the Ftrace specific files
14       found in the debugfs file system under the tracing directory. A COMMAND
15       must be specified to tell trace-cmd what to do.
16

COMMANDS

18           record  - record a live trace and write a trace.dat file to the
19                     local disk or to the network.
20
21           report  - reads a trace.dat file and converts the binary data to a
22                     ASCII text readable format.
23
24           hist    - show a histogram of the events.
25
26           options - list the plugin options that are available to *report*
27
28           start   - start the tracing without recording to a trace.dat file.
29
30           stop    - stop tracing (only disables recording, overhead of tracer
31                     is still in effect)
32
33           extract - extract the data from the kernel buffer and create a trace.dat
34                     file.
35
36           reset   - disables all tracing and gives back the system performance.
37                     (clears all data from the kernel buffers)
38
39           split   - splits a trace.dat file into smaller files.
40
41           list    - list the available plugins or events that can be recorded.
42
43           listen  - open up a port to listen for remote tracing connections.
44
45           restore - restore the data files of a crashed run of trace-cmd record
46
47           stack   - run and display the stack tracer
48
49           check-events - parse format strings for all trace events and return
50                          whether all formats are parseable
51

53       -h, --help
54           Display the help text.
