源中自带此命令,直接安装
iotop是管理命令,普通用户没有权限运行.
iotop键盘操作方式:
: 左右键切换排序列
r : 反向排序当前列,在列名后面有一个方向箭头指示,由大到小
o : 切换只显示有i/o活动的进行,等同 --only选项
p : 切换只显示进程,不显示多线程,等同--processes选项
a : 切换显示累加值,而不是带宽值,等同--accumulated选项
i : 改变I/O优先级
q : 退出
其它任何键: 刷新
运行

- [t@bjb0541 ~]$ sudo iotop --help
- Usage: /sbin/iotop [OPTIONS]
-
- 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, i to change I/O priority, q to
- quit, any other key to force a refresh.
-
- 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)
