simple top-like I/O monitor
  3 reviews

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.

Great tool for finding out what app is excesively using your disk. In my case it was older version of firefox with broken disk cache management.

A great app - I use it nearly as much as top.
