Metrics

Every metric starts with cv4pve_. The pages of this section list each one with its type, labels, unit and meaning, grouped by what it describes. This page explains the conventions they share and indexes them all.

Guests, storages and nodes are identified by the id label, which is the resource ID used by Proxmox VE itself:

Resource id
Node node/pve01
VM qemu/100
Container lxc/101
Storage storage/pve01/local-zfs, one per node, also for a shared storage
Cluster (only in cv4pve_up) cluster/pve-cluster

Per-node metrics use a node label with the node name instead.

Names, tags, versions and other text are not repeated on every series: they are labels of an …_info metric whose value is always 1: cv4pve_guest_info, cv4pve_node_info, cv4pve_storage_info, cv4pve_node_version_info, cv4pve_node_subscription_info, cv4pve_cluster_info. Join them in a query to add the label you need:

# Memory used by each guest, with its name and node
cv4pve_guest_memory_usage_bytes
* on (id) group_left (name, node) cv4pve_guest_info

A state with a fixed set of values (a guest lock, an HA state, a subscription status) is exported as one series per possible value, with a state (or status) label, and value 1 for the current state and 0 for the others. The alert is then a plain comparison, and a guest that stays locked keeps the same series:

cv4pve_guest_lock{state="backup"} == 1
  • Sizes are in bytes, durations in seconds, points in time are Unix timestamps in seconds.
  • …_ratio metrics go from 0 to 1.
  • Metrics ending in _total are counters: use them with rate() or increase(). A counter goes back to zero when Proxmox VE resets it (a guest restarted or migrated) or when the exporter restarts; Prometheus handles both.
  • Everything else is a gauge, except cv4pve_api_request_duration_seconds, a histogram.

The metrics built from the two cluster-wide calls, /cluster/status and /cluster/resources, are always exported. The others come from a collector, turned on and cached by a setting. A collector that is off exports no series at all.
