Why I Use It
As my lab has grown across multiple nodes, jumping between individual Proxmox interfaces gets old quickly. Proxmox Datacenter Manager gives me one place to see all of them — resource usage, VM and container status, and overall cluster health — without having to log into each node separately. It is still fairly new software but it is maturing fast and already makes multi-node management noticeably more convenient.
