Demonstrations of bitehist.py, the Linux eBPF/bcc version.
This prints a power-of-2 histogram to show the block I/O size distribution.
A summary is printed after Ctrl-C is hit.

kbytes : count distribution
0 -> 1 : 3 | |
2 -> 3 : 0 | |
4 -> 7 : 211 |********** |
8 -> 15 : 0 | |
16 -> 31 : 0 | |
32 -> 63 : 0 | |
64 -> 127 : 1 | |
128 -> 255 : 800 |**************************************|
This output shows a bimodal distribution. The largest mod of 800 I/O were
between 128 and 255 Kbytes in size, and another mode of 211 I/O were between
4 and 7 Kbytes in size.
Understanding this distribution is useful for characterizing workloads and
understanding performance. The existence of this distribution is not visible
from averages alone.
