We mentioned earlier that there are many Linux system monitoring tools that can be used to monitor system performance. However, we estimate that more users may prefer tools (top commands) that are included in most Linux distributions ). The top command is a real-time task manager in Linux. it is also used to find the system performance in the GNU/Linux release. We mentioned earlier that there are many Linux system
