Memory disk and CPU peaks
Every 3 or 4 days my ram, cpu and disk hits the roof and I am not sure why?
Does anyone know why this might be happening or how I can log this to view the processes latter?
Cheers

Install these utils so you can gather historical data:
apt install atop sysstat
then:
service atop start
service sysstat start
My wild guess would be that every few days bots (ex: googlebots) try to re-index your site simultaneously or aggressively. And that causes the memory/cpu spikes you're observing. It could also be malicious bots brute forcing your authentication pages. Review your access logs or analytics to try to understand what's happening.
