Published on 17th June, 2021, 2:45 PM

Sar is a system utility that gives us many ways to examine performance on a Linux system. It provides details on all aspects of system performance including system load, CPU usage, memory use, paging, swapping, disk usage, device load, network activity, etc.

The name "sar" stands for "system activity report," and it can display current performance, provide reports that are based on log files stored in your system's /var/log/sa (or /var/log/sysstat) folder, or be set up to automatically produce daily reports.

Disaster strikes

He also found himself unable to save files and in a very challenging situation since it is the only system he has at his disposal and he needs the system to get his work done.
