Running services, network usage, memory usage, bandwidth, disk I/O, successful logins, whether the thing is even alive, etc…
So far my only method has been “hope and pray”.

I just look at the console.
Monit, simple to setup, gets the job done, runs on my router too.
I use FreeBSD so I don’t need to check it to make sure it’s working properly
Wasn’t there an RCE recently discovered with AI?
You’d need to be running kerberised NFS in the kernel, give the attacker access to your NFS server, and have a valid kerberos login
I don’t know anyone sharing NFS access let alone opening it up on the open internet
Lights are on, server is on.
I recently found out that this is not always true.
I never said anything about it responding.
Kernel panic?
My kernel is chill.
It’s running the private DNS for my phone. If it goes down, I realise quite quickly.
Uptime Kuma for monitoring web service status (just like if the jellyfin, etc. website is up), and Zabbix for monitoring system metrics like CPU/Memory/Disk I/O, etc. Zabbix can do a whole lot, but can also get a little complicated. There are plenty of guides out there for configuring it though.
Gatus. Works and easy incremental set up.
Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I’ve seen in this thread:

3 acronyms in this thread; the most compressed thread commented on today has 6 acronyms.

Use service, wait for 404 or data loss…
I go the easy route with munin and wazuh. It comes with a ton of stuff preconfigured
Ultime Kuma, Beszel and Ntfy
Icinga and Phare Uptime
I have a robust monitoring system for my Jellyfin server, been running for the last few years. Checks in periodically, at least once per 24 hours and notifies me if it’s down. Doesn’t use any electricity, but does consume a good amount of Cheerios and mac & cheese.
Lies! It uses electricity!
Indirectly. But as another commenter pointed out, it balances out with the tax rebates.
Does this monitoring system also happen to be a dependent on your taxes?
I’ve got a few of those services running.
Cockpit. Total gamechanger for me. I don’t have to ssh to my boxes individually to see what’s going on. Instead it’s a web UI AND you can connect basically every server you want to one instance.

That said. For individual servers?
htop/nmon(Get nmon straight from the source! https://nmon.sourceforge.io/pmwiki.php) for a birds-eye sysmon view of thingsps -ef | grep <whatever you're looking for>for investigating stuck/hung/zombie processesdmsegtail -f /var/log(or whatever log file you care about)netstatfor net statistics (i think ntop used to be a thing but idk anymore>…)df -hto look at disk usagethose are all that come to mind right away.
EDIT: formatting and quick explanation of what each tool does
How do you configure adding multiple servers to the same instance?
Lol I go to all of my server’s specific cockpit addresses, sounds like I’m doing it wrong, I’ll need to look at connecting them
So it turns out… you can’t connect them anymore… The feature is deprecated

(also, I wanted to just link my response from another user who had asimilar question but for whateVER reasyon, Alx won’t let me??)
It’s amazing the risk profile of that.
I pay a group of schoolchildren to refresh a group of browser tabs and yell if anything isn’t responding.
There are plenty of previous threads with recent answers if you search.
