How to tract vitals of many servers?

You have to work out if you basically want an uptime monitor, that may or may not monitor a few other things like CPU load. Or if you basically want a server metric monitor that gives you lots of things (like disk latency, network IO, database performance, etc.) and also functions as an uptime monitor as a result.

You also have to decide if you want a free tool or a paid service. All uptime monitors end up being paid - I'm yet to find a free one that monitors usefully frequently. There are both paid and free server monitors. Free ones: Munin, Nagios, Zabbix (on-premises).

We use Grafana but we previously used Zabbix and also Nagios.

I've heard Uptime Robot no longer allows free monitoring and some have moved onto Hetrix, which has been mentioned.

Setup a Zabbix server and install clients on your other servers that point back to the Zabbix server.
You can review all clients in once interface.

Paid is no problem, if it's good dashboard and not too expensive, I currently have +50 servers and of course will have much more over the coming years.

Honestly I just need a few things from every "website" or server.

- CPU usage (to see if it is receiving high traffic or is compromised by kinsing or something)
- Snapshot of website if it is live or not.

I just need to know if a website is alive and well, everything else is not very important.

And a simple dashboard of "alerts" like high CPU usage or if IP not pingable etc. Ideally a list of all sites with snapshots of homepage to make sure it's not an error message as every website is going through cloudflare (their free tier is really good)

In a simple way you can use the “uptime robot” program, if you want to go into more detail and analyze them graphically, grafana will be for you.

+1 for Munin. Old as the hills and it shows, but still gets the job done.

Have you tried Nginx Amplify? Looks very basic and exactly what i need for my sites since I use nginx on all of them

I haven't. You might want to run Munin or similar along with something like Nginx Amplify. Munin and tools of its kind won't monitor nginx/apache/litespeed that closely, but will provide snapshots of the overall health of your server and can be very valuable if you are having performance issues.

Hetrix tools is what I recommend. It is beginner friendly unlike some more advanced tool mentioned here.
First install an uptime monitor and then "server monitoring agent", which will give you nice graph about all the vitals
