If you have a mix of Proxmox nodes and external servers, getting a clean, truthful view of CPU, memory and disk is strangely hard. Proxmox’s built-in charts blur the line between free, cached and used memory, which makes planning resources awkward. I also needed email alerts for low disk space and high CPU or memory after learning the hard way that a full disk can freeze VMs and turn recovery into a risky dance. Finally, I wanted all nodes in one place, not just Proxmox, but remote KVMs, VPSs and dedicated servers from various providers.

It’s popular among home lab enthusiasts and IT pros who want enterprise-grade tools without enterprise-level licensing fees.
This post takes a deep dive into what Proxmox is and how to set up a powerful home lab using it; from the basics of installation to more advanced configurations like VLANs, backups, and clustering.
