I built a basic Proxmox overhead calculator after nearly OOMing my cluster! (unknownuniverse.uk)

After coming close to running out of resources last week and having to re-purpose another device turning it into a 3rd Proxmox node, it got me thinking about how easily ZFS ARC cache and VM overhead sneak up on you.

So, I built a basic tool for rough guidance.

It calculates vCPU overcommit ratios and RAM allocation locally in your browser. Just pure client-side math so you don't accidentally OOM your hypervisor like I almost did. Inputs stay right in your browser and aren't saved anywhere.

Feedback or sanity checks on the math are welcome.

I had the bulk of the tool written myself but used AI to help tweak the final polished version. I've always been open about my AI use in the past, I have a post on my blog about the subject. AI doesn't generate my content, all ideas and opinions are my own but I do use it as a tool for refinement when needed.
