    Command:

    trace-cmd

    
    
    

    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.
