Hello,
We are using a droplet with 4 GB Memory / 80 GB Disk / FRA1 - Ubuntu 18.10 x64. We have installed varnish, nginx 1.15.5, php 7.2. Mysql is hosted on another droplet. In droplet graphs php-fpm7.2 seems to use CPU 95% and Memory 46%. I have tried many configurations for php-fpm without fixing my problem.
Previously i had my droplet using php-fpm 7.0 and was working normally. Any suggestions please?

Hi, For starters create separate php-fpm pools for each domain, and you will see in htop which domain creates the load. Then you will need PHP profiling to find the bottleneck in the code of this site.

On my /etc/php/7.2/fpm/pool.d/www.conf we are having the following:
pm = dynamic pm.max_children = 10 pm.start_servers = 4 pm.min_spare_servers = 2 pm.max_spare_servers = 6 pm.max_requests = 500
Using top -c you can see high CPU usage (i cannot find a way to check which domain is each pid refer to):
