How to track disk usage (write/read and other cool stuff) in realtime with fashion of top in the only right system in shell?
It would be cool if it could monitor specific directory.
01 Answer
There's a tool (top like) to track I/O :
iotop -oPa$ apt-cache show iotop
(...)
Description-en: simple top-like I/O monitor iotop does for I/O usage what top(1) does for CPU usage. It watches I/O usage information output by the Linux kernel and displays a table of current I/O usage by processes on the system. It is handy for answering the question "Why is the disk churning so much?". . iotop can only run under a Linux 2.6.20 or later kernel built with the CONFIG_TASKSTATS, CONFIG_TASK_DELAY_ACCT, CONFIG_TASK_IO_ACCOUNTING and CONFIG_VM_EVENT_COUNTERS build config options on.
