Proxmox Input Plugin

This plugin gathers metrics about containers and VMs running on a Proxmox instance using the Proxmox API.

⭐ Telegraf v1.16.0 🏷️ server 💻 all

Global configuration options

Plugins support additional global and plugin configuration settings for tasks such as modifying metrics, tags, and fields, creating aliases, and configuring plugin ordering. See CONFIGURATION.md for more details.

Configuration

toml

# Provides metrics from Proxmox nodes (Proxmox Virtual Environment > 6.2).
[[inputs.proxmox]]
  ## API connection configuration. The API token was introduced in Proxmox v6.2.
  ## Required permissions for user and token: PVEAuditor role on /.
  base_url = "https://localhost:8006/api2/json"
  api_token = "USER@REALM!TOKENID=UUID"

  ## Node name, defaults to OS hostname
  ## Unless Telegraf is on the same host as Proxmox, setting this is required.
  # node_name = ""

  ## Additional tags of the VM stats data to add as a tag
  ## Supported values are "vmid" and "status"
  # additional_vmstats_tags = []

  ## Optional TLS Config
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  ## Use TLS but skip chain & host verification
  # insecure_skip_verify = false

  ## HTTP response timeout (default: 5s)
  # response_timeout = "5s"

Permissions

The plugin will need to have access to the Proxmox API. In Proxmox API tokens are a subset of the corresponding user. This means an API token cannot execute commands that the user cannot either.

For Telegraf, an API token and user must be provided with at least the PVEAuditor role on /. Below is an example of creating a telegraf user and token and then ensuring the user and token have the correct role:

## Create a influx user with PVEAuditor role
pveum user add influx@pve
pveum acl modify / -role PVEAuditor -user influx@pve
## Create a token with the PVEAuditor role
pveum user token add influx@pve monitoring -privsep 1
pveum acl modify / -role PVEAuditor -token 'influx@pve!monitoring'

See this Proxmox docs example for further details.
