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


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


       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.


       bno_plot was written by Alan D. Brunelle.  This man  page  was  created
       from the blktrace documentation by Bas Zoetekouw.
