Modify this line to get what you want ( there's no need to restart cron). Is responsible for running debian-sa1 every 10 minutes ( debian-sa1 is a wrapper over sa1 if your distro is neither Debian nor its derivative, you should probably use sole sa1 instead). This line 5-55/10 * * * * root command -v debian-sa1 > /dev/null & debian-sa1 1 1 In my Kubuntu the relevant file is /etc/cron.d/sysstat. Sysstat uses cron to run sa1 periodically. Sar reads files where scripts from the sysstat's set of tools write to. The best way to install the htop is using snap because it works well on any of the Linux distros.I tried using sar but I got results for a 10-minute interval. In most of the distros, the top is installed by default, and we have to install the htop manually. In this, we can also scroll horizontal as well as vertical. As compared to the top, the htop UI has better quality. The htop's default display is more user-friendly. On the other hand, the htop command offers a better quality-of-life experience. In terms of system monitoring both commands offer the same functionality.

st: st is the time lost for running a virtual machine, which is also called 'steal time.'.

si: si is the time spent servicing software interrupts.

hi: hi is the time spent servicing hardware interrupts.

wa: wa means the amount of time spent waiting for I/O request to complete.

ni: ni is the time spent to run the process with a custom (manually set) excellent value.

sy: sy is the time spent running 'kernel space' processes.

us: The amount of time it takes to run the process for individual users in the 'user space.'.

Each value indicates how much time the CPU spends performing a task. In the above output, the main line to focus on is the line number third.
