Now idle 4 cores, so all ok. Read in internet tips how to locate most load users/scripts. Also check php logs, apache logs etc.. maybe some website under ddos
 
maybe ddos attack.
if you have Pro Pack. check in this
Admin -> System Info & Files -> Resource Limit

Who have high CPU, Mem, Task, disk IO usage.

if you use PHP-FPM
please focus at "task". When any users got DDOS, the Task will increase to max or equal to "pm.max_children" of php-fpm.
 
there have. But it too much args. I can't remember. so just follow in Docs
www.commandlinux.com

systemd-cgtop linux command man page

A compilation of Linux man pages for all commands in HTML.
www.commandlinux.com www.commandlinux.com

this commands will show all group/users. it need to make custom parser.
like combined with "grep"

some value don't show correctly you need to enable delegate.

[Optional] cgroup v2 | Rootless Containers

[Optional] cgroup v2
rootlesscontaine.rs rootlesscontaine.rs

scroll down section "Delegate=cpu cpuset io memory pids"

anything suspicious ?
 
It's all ok now:
idle 441% - this mean 4.4 cores free
steal 146% - For virtual machines the steal-percentage is shown ('steal'), reflecting the percentage of cpu time stolen by other virtual machines running on the same hardware.

you need to find out what causes high load, or stolen CPU resources, or real trafic increase - for this purposes you must monitor server health with graphs to see what changed when load increased
 
you can use at least: Prometheus+Grafana+node exporter
but for prometheus+grafana better to use separate VPS. How to install/configure - look at internet
