NAME
       bno_plot - generate interactive 3D plot of IO blocks and sizes


SYNOPSIS
       bno_plot [ -h | --help ]
                [ -v | --verbose ]
                [ -K | --keys-below ]
                [ <file...> ]


DESCRIPTION
       bno_plot is a visualization tool for the block layer IO tracing tool called blktrace(8).  As noted in its
       documentation,  blktrace  is a block layer IO tracing mechanism which provides detailed information about
       request queue operations up to user space.

       bno_plot utilizes gnuplot to generate a 3D plot of the block number output from btt.  If no  <files>  are
       specified,  it  will  utilize all files generated after btt was run with -B blknos (meaning: all files of
       the form blknos*[rw].dat).

       The -K option forces bno_plot to put the keys below the graph.  If it is  not  specified,  all  keys  for
       input  files  are  put  in  the upper right corner of the graph. If the number of devices exceed 10, then
       bno_plot will automatically push the keys under the graph.

       To use this utility, the gnuplot package needs to be installed.

       To exit the plotter, enter 'quit' or ^D at the 'gnuplot> ' prompt.
