How to determine what is causing high RAM usage?

Plesk Repair Kit extension includes functionality to monitor in real-time CPU and RAM usage per subscription.

This helps with current status - but I've been getting spikes that resolve within 10 minutes or so. I've yet to get the notice email and login fast enough to catch what's causing this. Is there a way to see what the memory usage was when the alert was generated?
This cached RAM and it seems to be mariadb that is using it all. If I run htop on the command line, I'm using 2GB of 6GB which I see on the charts, but the cache usage is through the roof and actually causing trouble.
I've already done that. The usage is not constant. I want to know what is causing it to spike.
