How do I monitor process I/O using iotop?

iotop is a utility for Linux that operates in a similar manner to the top utility, but it displays the I/O activity of each process.


First, you must enable the EPEL software repository:

For servers running RHEL 5:

rpm -Uvh

For servers running RHEL 6:

rpm -Uvh

To install iotop:

yum -y install iotop


To display only the processes currently performing I/O:

iotop -o

To display the manual:

man iotop
