i always suffering from this repeated high memory usage of apache & php-fpm module, even i upgraded my vps to 8 Gb RAM but the same happened everyday, and i only host 3 domains on ( 4 cores Xeon v4 - 8 Gb RAM ).
So could you recommend me any solution
The memory usage does not seem to be a big issue, but the threshold is very low. It seems to be somewhere around 800 MB? Maybe you can increase the warning threshold to 2 GB. This can be done with the "Settings" icon (the gear icon) the the Grafana extension.
Monitoring (former Advanced Monitoring) helps to keep your Plesk running smoothly by tracking the server resource usage and notifying you when one or more resource usage reaches a predefined threshold.
