iotop tool to find bandwidth used during the sampling period

DISK READ and DISK WRITE are the block I/O bandwidth used during the sampling
period. SWAPIN and IO are the percentages of time the thread spent respectively
while swapping in and waiting on I/O more generally. PRIO is the I/O priority at
which the thread is running (set using the ionice command).

Controls: left and right arrows to change the sorting column, r to invert the
sorting order, o to toggle the –only option, p to toggle the –processes
option, a to toggle the –accumulated option, q to quit, any other key to force
a refresh.
Usage: /usr/sbin/iotop [OPTIONS]

Options:  --version             show program's version number and exit  -h, --help            show this help message and exit  -o, --only            only show processes or threads actually doing I/O  -b, --batch           non-interactive mode  -n NUM, --iter=NUM    number of iterations before ending [infinite]  -d SEC, --delay=SEC   delay between iterations [1 second]  -p PID, --pid=PID     processes/threads to monitor [all]  -u USER, --user=USER  users to monitor [all]  -P, --processes       only show processes, not all threads  -a, --accumulated     show accumulated I/O instead of bandwidth  -k, --kilobytes       use kilobytes instead of a human friendly unit  -t, --time            add a timestamp on each line (implies --batch)  -q, --quiet           suppress some lines of header (implies --batch)
