Iotop is a Python program with a top like UI used to show of behalf of which process is the I/O going on. It requires Python >= 2.7 and a Linux kernel >= 2.6.20 with the CONFIG_TASK_DELAY_ACCT CONFIG_TASKSTATS, CONFIG_TASK_IO_ACCOUNTING and CONFIG_VM_EVENT_COUNTERS build options on and for Linux kernels since 5.14, the kernel.task_delayacct sysctl enabled. To run a local version of iotop: $ ./iotop.py The documentation is available in the man page: $ man ./iotop.8 To install iotop, you should use a package provided by your distribution. If you really want to install this version of iotop on your system, do (as root): # ./setup.py install For an alternative implementation of iotop that is written in C, uses less resources and has more features, please take a look at this project: https://github.com/Tomas-M/iotop Packages of both implementations are available in several distributions: https://repology.org/project/iotop-python/versions https://repology.org/project/iotop-c/versions To chat with the iotop community join #iotop on the libera.chat IRC network. Please mention which implementation is in use when asking questions there. -- Guillaume Chazarain http://guichaz.free.fr/iotop/
