Metrics of resources used in cPanel
For real time, simply check column right of your cPanel, do page refresh to update...
Or, you can use also SSH without the need to refresh and to see more details about processes : see details at bottom of this article.

Note that graphics can not accurately record CPU spikes that can occur for only a few seconds.
You must observe this regularly at different time frames : day, week, month (day, week, month).
You see "Database" in first graph which indicates proportion of your processor allocated which is used by your databases

This is very important in the sense that it can cause slowdowns of your sites, error pages, and if it causes an overload of server php process persistently, you will soon receive an alert message of our hand.

If your traffic High does not explain the high level of resource utilization, then it must be analyzed in detail, here are the causes in general :

1 - module/plugins uses coming from third parties or improperly installed or poorly coded, or use of multiple modules in conflict (typical security modules) are in 90% cases reasons of improper working of websites. Uninstall completely any unused plugins/modules, keep the quality ones, and make sure they have a unique role. Finally, many modules requires you to read its editor manual, contact them to troubleshoot unknown issues.

We always recommend having an average CPU used up 60% in order to have a margin for traffic spikes, the administration work, also it is not necessary that the RAM is full : see if a module or something is not buggy, otherwise, you need more memory because in case of saturation, the pages are displayed with mistakes sometimes.

You may have chosen a plan that possibly not suited or not anymore to your needs resources such as CPU, RAM, disk space, number of processes.

See our article :

To see real-time the use of your processor, you must use SSH with software putty, type command :
/usr/bin/top -d 00.50
Open another shell window with putty
You can check what is doing one process, by his PID number, if number PID is 22596, type :
strace -p 22596

To kill all processes :
type in your SSH console : kill -15 -1 , and press Enter
(this will turn off also your SSH session, reconnect to SSH, and top again to see that all came down)
