This check monitors a Proxmox VE node's status and subscription status. The service state for each status can be individually configured in the ruleset (OK, WARN, CRIT). By default, node status "online" and subscription statuses "new" and "active" are considered OK, while other statuses trigger appropriate warning or critical states. It shows the node status, subscription status and time until expiration, Proxmox VE version and number of hosted VMs.
