Saidar is a simple system monitoring tool for Linux


For a system admin, its always exciting to learn new commands to monitor system resources, and here is a new one. Its called Saidar and is a very small tool. Even simpler than Nmon and Glances. It displays a small screen full of statistics on a variety of system resources that you might want to monitor.

Saidar is a part of the libstatgrab suite.

The man page definition is ...

saidar  is  a  curses-based  tool for viewing the system statistics available through libstatgrab. Statistics include CPU, processes, load, memory, swap, network I/O, disk I/O, and file system information.

The output keeps updating at an interval and looks similar to this
