How to monitor the state of the processor, disk and RAM metrics, Nginx, PHP, MySQL?

Question

Monitoring

Friends,
we need a system with which to view graphs
- server CPU load
- server memory usage
- hard disk
usage - Internet channel usage
and receive email and sms notifications at critical values.
You also need to monitor the status and if a service stops, send email and sms notifications
- Nginx
- PHP
- MySQL
- Redis
In addition, you need to view metrics for all the services listed above, for example
- traffic to NGINX
- how much RAM and processor it uses MySQL.
Is it possible to monitor servers and applications using any one system?
I would be very grateful if you share your experience.
