It display system summary information, the list of processes currently being managed by the Linux kernel. The top command provides a dynamic real-time view of the running process on a Linux system. The Linux top command is the best and most well known command that everyone uses to monitor Linux system performance.

1) top command to determine high CPU usage in Linux We have already described in our previous article how to find high memory consumption processes in Linux. I’d like to go with the top command for most reasons instead of ps, but both will produce effective results, so you can choose the one you like. Both of these commands are widely used by Linux administrators to troubleshoot high CPU Usage on Linux. I believe there are only two primary commands that can identify and determine if your CPU is under stress, such as top command and ps command.

There are situations where you often have to deal with application sluggishness or unresponsive application due to high CPU usage in Linux.
