With the ‘mpstat’ tool you can also take CPU usage snapshots at regular intervals. The ‘mpstat’ command provides the same output as the ‘ htop‘ command but in a more concise format. Once the utility is installed type in the given command to get a report for each active processor. To install mpstat type in the given command in the terminal and press enter. If no activity has been selected, then the default report is the CPU utilization report. The mpstat command can be used both on SMP and UP machines, but in the latter, only global average activities will be printed. Global average activities among all processors are also reported. The mpstat command writes to standard output activities for each available processor, processor 0 being the first one. Mpstat – Report processors related statistics. The command will start the installation process, once it’s finished run the given command to show the current CPU usage of the system. To install htop type in the given command in terminal and press enter. Tasks related to processes (killing, renicing) can be done without entering their PIDs. It is similar to the top tool but allows you to scroll vertically and horizontally, so you can see all the processes running on the system, along with their full command lines, as well as view them as a process tree, selecting multiple processes and acting on them all at once. htop is a free (GPL) ncurses-based process viewer for Linux. In this guide, we will explain to you how to check CPU usage in Ubuntu 18.04.
Because of that tracking and monitoring the CPU efficiently is essential. But too much context switching will also cause a rise in CPU usage. However If a CPU core is unable to handle the heavy load of an application, it results in context switching of tasks. Since the system performs faster and more efficiently in the case of a higher core system. Monitoring the performance of the CPU is essential to debug processes that are causing errors.
