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.

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