Our server went down as cpu usage is 100% due to some process. We are not able to find that process even in logs. Some cron is running. How to identify it?

Hi there,
I recently answered a similar question here.
One of the tools that I use to do so is the
top
command. Thyetop
command works quite well, all you need to do is to runtop
in your terminal and then hit one of the following keys to sort the processes by the information that you are looking for:M
- Sorts by current resident memory usageP
- Sorts by current CPU usage (this is the default)?
- Displays a usage summary for all top commandsThis is very important information to obtain when troubleshooting a slow server or a computer. This would help you make a decision on what processes to kill/software to uninstall.
An alternative of
top
ishtop
. It is an interactive system-monitor process-viewer and process-manager. It is designed as an alternative to the Unix program top. Some of the benefits ofhtop
is that it comes with colors and is interactive, meaning that you could scroll the process list horizontally and vertically using the arrow keys, kill a process by pressing the F9’, sort the processes by Memroy/CPU usage and etc. by just clicking with your mouse.Let me know how it goes!
Best,
Bobby
