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.
