BNO_PLOT(1) BNO_PLOT(1)
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.
