Ask HN: Best solution for homelab service monitoring?

I'm running a lot of different amazing software tools on a variety of hardware. I've got a bunch of Vagrant machines on my Linux boxen, experimenting with ARM machines on my macOS m2 using multipass and much more.

And, occasionally, one of the disks on my machines fills up. And, then my vagrant machine suspends.

Or, I reboot a machine and the VM does not come up automatically, because I forgot that that service isn't docker with restart set.

What are people using to make sure homelab services are running correctly?

My goal would be something that:

  * Has a simple dashboard
  * Should it be an agent on the VM, or an external process that checks from afar?
  * Good backup and restore story so I can rebuild the service and move to another server if I need to.
  * Polyglot checks: I want to see CPU, memory, disk space usage. But, I also want to check services on the VM, like docker. And, use SSH to do manual checks.
  * Lightweight learning curve
  

I'm using Uptime Kuma for monitoring HTTP and SSH services and I love it. But, with Uptime Kuma cannot ssh into a server, it only checks to see if the SSH daemon is up, and I would love to actually enter the machine and do a health check which could be customized.

Is there a single service that I could use for this? Or, should I wire together a bunch of smaller tools and put them into a centralized dashboard somehow?

I'm looking at dashy and it looks great. But, as of yet, I'm unsure how I can just "add SSH check for this hostname" and "add HTTP status check for this hostname" and "check diskspace for this hostname" and get it working without a lot of confusion.
