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.
