Find out what is loading the processor on vps debian?

Question

linux

Good afternoon!
On vps, such a picture is regularly observed joxi.ru/8AnWYkOTPyQprO , la jumps up to 6-8 for no reason, but I notice too late and I don’t have time to see the processes.
What can you think of to remove at least a dump from the top at this moment? Zabbix did not find anything in the dock about this.
Thank you.

Answer 1

man atop

Answer 2
