.SH 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 \fI<files>\fR are specified, it will utilize all files generated after
|
|
btt was run with \fI-B blknos\fR (meaning: all files of the form \fIblknos*[rw].dat\fR).
|
|
|
|
The \fI-K\fR 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.
|
|
