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.

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.
 

OPTIONS

*-h, --help

Displace the help text.

Other options see the man page for the corresponding command.
