dash now reads your whole Proxmox VE cluster through its one Proxmox connection (#46): every node, the cluster's quorum, totals, and every guest and storage on its own node. A minor release: some payloads change shape; the settings do not.

New

  • Clusters through one connection. dash asks whichever node plugins.proxmox.url reaches for the whole cluster. A standalone server is a cluster of one.
  • VMs page:
    • a cluster summary: name, quorum, nodes online, and the CPU, memory and storage totals of the online nodes;
    • a card per node: its state, CPU, memory, uptime, Proxmox VE version, CPU model and guests;
    • each VM and template shows its node, and the activity table has a Node column.
  • Per-VM calls go to the right node. A VM's detail and console use its own node, follow a guest that just migrated, and answer at once for a guest of an offline node.
  • Storage: every node's storages, a shared one (NFS, Ceph) listed and counted once, with totals.
  • Overview: the topology draws one host per node, each VM under its node.
  • Attention: an offline node and a cluster that lost quorum are critical items.
  • Hardware page: the Proxmox facts of the host's own node.

Upgrade notes

  • Settings: nothing to change. plugins.proxmox.node no longer chooses what dash reads; it names the node the Hardware page's host is. A cluster of several nodes no longer needs it for the plugin to run, but its Hardware page does (or plugins.hardware.hosts[0].nodename).
  • Token: the cluster's name and quorum need Sys.Audit on / (PVEAuditor on / has it). Without it everything else works and the quorum reads as unknown.
  • API and clients:
    • proxmox.node is replaced by proxmox.cluster;
    • VMs and tasks carry node;
    • storage refs carry the node (proxmox:Storage/<node>/<name>; a shared one is proxmox:Storage/<name>);
    • core.overview's topology has hosts (one per node) instead of host.
  • Rolling back to v0.14.11: no settings change, but a cluster of several nodes then needs plugins.proxmox.node again.
