DESCRIPTION

19       bno_plot  is  a  visualization tool for the block layer IO tracing tool
20       called blktrace(8).  As noted in its documentation, blktrace is a block
21       layer  IO  tracing  mechanism which provides detailed information about
22       request queue operations up to user space.
23
24       bno_plot utilizes gnuplot to generate a 3D plot  of  the  block  number
25       output  from  btt.   If  no  <files> are specified, it will utilize all
26       files generated after btt was run with -B blknos (meaning: all files of
27       the form blknos*[rw].dat).
28
29       The  -K  option forces bno_plot to put the keys below the graph.  If it
30       is not specified, all keys for input files are put in the  upper  right
31       corner  of the graph. If the number of devices exceed 10, then bno_plot
32       will automatically push the keys under the graph.
33
34       To use this utility, the gnuplot package needs to be installed.
35
36       To exit the plotter, enter 'quit' or ^D at the 'gnuplot> ' prompt.
