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.
