Iotop

As a software review, it must be mentioned how useful Linux has always been in displaying the amount of input/output (I/O) going on, thanks to the "bi" and "bo" columns of the "vmstat 1" command. However, Iotop takes that functionality to the next level. Developed using Python, it offers a top-like User Interface (UI) that specifies exactly which process the I/O is taking place on behalf of.

The tool requires Python version 2.5 or higher, as well as a Linux Kernel version 2.6.20 or later, and provides a simple and easy-to-use way to monitor and track I/O activity. It is especially helpful in identifying processes that are consuming excessive I/O, as it allows users to pinpoint them in a precise manner, thus enabling them to optimize system performance and resource utilization.

Overall, Iotop is a highly effective tool for users who require more detailed I/O monitoring and tracking options than the standard tools offered by the Linux operating system. Its intuitive UI design, ease of use, and compatibility with the latest versions of Python and Linux make it a must-have tool for any system administrator or developer, looking to optimize their system performance.
