If you want to see a clear view of the top command output for further analysis, this is a best way to run the top command in the batch mode.Īlso, you need to understand the top command output to fix the performance problem on the system. It displays various system information such as CPU usage, Memory usage, Swap Memory, Number of running processes, system uptime, system load, Buffer Size, Cache Size, Process PID, etc.īy default, it sorts the top output with the CPU usage and updates the top command data every 5 seconds. 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. If you want to check which processes are hamming the CPU, you must use the appropriate commands to know the overall consumption processes of the CPU. This happens when your Linux system CPU is too busy, usually it is not available to process other requests and the pending requests have to remain in the queue and wait until the CPU is free. There are situations where you often have to deal with application sluggishness or unresponsive application due to high CPU usage in Linux.
