    Command:

    trace-cmd-reset

    
    
    
    

    SYNOPSIS

           trace-cmd reset [OPTIONS]
    
    
    

    DESCRIPTION

           The trace-cmd(1) reset command turns off all tracing of Ftrace. This
           will bring back the performance of the system before tracing was
           enabled. This is necessary since trace-cmd-record(1), trace-cmd-stop(1)
           and trace-cmd-extract(1) do not disable the tracer, event after the
           data has been pulled from the buffers. The rational is that the user
           may want to manually enable the tracer with the Ftrace pseudo file
           system, or examine other parts of Ftrace to see what trace-cmd did.
           After the reset command happens, the data in the ring buffer, and the
           options that were used are all lost.
    
    
    

    OPTIONS

           -b buffer_size
               When the kernel boots, the Ftrace ring buffer is of a minimal size
               (3 pages per CPU). The first time the tracer is used, the ring
               buffer size expands to what it was set for (default 1.4 Megs per
               CPU).
    
                   If no more tracing is to be done, this option allows you to shrink the
                   ring buffer down to free up available memory.
    
                   trace-cmd reset -b 1
