The dashboard consists of five lines, each containing some metrics. The first line shows short information about the system, such as the uptime, load average, and the number of users currently logged in. Tasks are shown in the second line. The third one shows CPU load, and the following two lines indicate memory usage.
In Linux, the top command displays helpful statistics about the system’s resources. It allows us to see CPU and memory consumption as well as process statistics for currently running services. Top can also be used to locate zombie processes. As a result, Linux administrators must know how to use the top command. The next section gives a quick explanation of the top command and demonstrates how to use it in practical situations. Top displays a list of currently executing processes in addition to normal CPU measurements by default. The initial half of the output might be thought of as a dashboard. The process list is displayed at the bottom of the page, and all running processes are displayed in real time.
Note that the commands you specify while running top are case-sensitive. For example, the n and N keys both perform different operations.
