Managing proxmox, virtual machines, and others (programming.dev)

Hey all, just hoping to get some advice on any software out there that can help me keep on top of all the VMs i'm running on my Proxmox instances, and potentially my other machines I have too.

I'm looking for a way to help me stay on top of updates and things like when the machine was last online, last rebooted etc etc. There are commercial products for such a thing, and I don't necessarily want to install any sort of Agent on each of the machines (if I can avoid it).

I looked at something like Homarr, but not sure if that's what i'm really after.

What recommendations do all you have?

As others have said, if your VMs are Linux, set up unattended_updates and forget about it.

If your VMs are windows, then Action1 is free up to 200 clients, it does need an agent installed, but that auto updates too.

Yep, I do that on Debian hosts, EL (RHEL/Rocky/etc.) have a similar feature.

However, you need to keep an eye for updates that require a reboot. I use my own Nagios agent that (among other things) sends me warnings when hosts require a reboot (both apt/dnf make this easy to check).

I wouldn't care about last online/reboots; I just do some basic monitoring to get an alert if a host is down. Spontaneous reboots would be a sign of an underlying issue.
