Frequently Asked Questions

Which monitoring areas are covered?

You will study CPU, memory, I/O, processes, threads, open files, continuous monitoring, and scheduled work so you can assess system activity as a whole.

What tools will I learn to use?

The lessons introduce tools and concepts including top, load averages, iostat, lsof, fuser, process threads, and cron.

Is this course useful for diagnosing slow systems?

Yes. It helps you distinguish CPU, memory, I/O, and process-related pressure before deciding where deeper investigation is needed.
