It’s been almost a week since we receive a site went down notification.
This site is built in PHP 7.2 and MariaDB, it is a legacy WordPress app that consumes a lot of ram and other resources, the response time on homepage: DOMContentLoaded: 2.40 s.
I have installed NETDATA on the server and uploaded some screenshots here:

PHP-FPM config:
pm.max_children = 100
pm.start_servers = 10
pm.min_spare_servers = 10
pm.max_spare_servers = 20
pm.max_requests = 500
Server (Dedicated vCPU Instance):
Intel Xeon Processor (Skylake, IBRS)
8 vCPU
32GB RAM
Any idea how to resolve this issue and what’s causing it?
