Proxmox Input Plugin

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

Introduced in: Telegraf v1.16.0 Tags: server OS support: 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

# 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.

Metrics

  • proxmox
    • tags:
      • node_fqdn - FQDN of the node telegraf is running on
      • vm_name - Name of the VM/container
      • vm_fqdn - FQDN of the VM/container
      • vm_type - Type of the VM/container (lxc, qemu)
      • vm_id - ID of the VM/container
    • fields:
      • status
      • uptime
      • cpuload
      • mem_used
      • mem_total
      • mem_free
      • mem_used_percentage
      • swap_used
      • swap_total
      • swap_free
      • swap_used_percentage
      • disk_used
      • disk_total
      • disk_free
      • disk_used_percentage

Example Output

proxmox,host=pxnode,node_fqdn=pxnode.example.com,vm_fqdn=vm1.example.com,vm_id=112,vm_name=vm1,vm_type=lxc cpuload=0.147998116735236,disk_free=4461129728i,disk_total=5217320960i,disk_used=756191232i,disk_used_percentage=14,mem_free=1046827008i,mem_total=1073741824i,mem_used=26914816i,mem_used_percentage=2,status="running",swap_free=536698880i,swap_total=536870912i,swap_used=172032i,swap_used_percentage=0,uptime=1643793i 1595457277000000000

InfluxDB OSS 2.9.0: API tokens are hashed by default

Stronger token security in InfluxDB OSS 2.9.0 — tokens are hashed on disk by default. Existing tokens are hashed on first startup and can’t be recovered afterward. Capture any plaintext tokens you still need before you upgrade.

View InfluxDB OSS 2.9.0 release notes

Hashed tokens authenticate exactly like unhashed tokens — clients and integrations keep working.

Also new in 2.9.0:

  • Configurable backup compression
  • Restore support for backups containing hashed tokens
  • Tighter Edge Data Replication queue validation
  • Flux upgrade
  • Compaction reliability improvements

Key enhancements in Explorer 1.8

Explorer 1.8 is now available with streaming data subscriptions (beta), line protocol preview, and query history & saved queries.

View Explorer 1.8 release notes

Explorer 1.8 includes new features and improvements that make it easier to ingest, explore, and manage data.

Highlights:

  • Streaming data subscriptions (beta): Stream data into Explorer from MQTT, Kafka, and AMQP sources.
  • Line protocol preview: Preview line protocol, schema, and parse errors before data is written.
  • Custom sample data: Generate custom sample datasets with line protocol and schema preview.
  • Query history and saved queries: Browse query history and save/re-run named queries.
  • Retention period management: Set, update, or clear retention periods on databases and tables.

InfluxDB 3.10 is now available

InfluxDB 3 Core 3.10 adds an automatic catalog format upgrade, a configurable query-concurrency limit, and processing engine improvements.

Key updates in InfluxDB 3 Core 3.10:

  • Catalog format upgrade: the on-disk catalog automatically upgrades from format v2 to v3 on first 3.10 startup. Migration is one-way—back up your catalog before upgrading.
  • --max-concurrent-queries: limit concurrent queries (adjustable at runtime).
  • GET /ready endpoint for readiness probes.
  • Processing engine: cross-database queries and trigger lockdown flags.

For more information, see the InfluxDB 3 Core release notes.

InfluxDB 3.10 is now available

InfluxDB 3 Enterprise 3.10 adds automated backup and restore, row-level deletions, and user management, with an automatic catalog format upgrade and performance preview improvements.

Key updates in InfluxDB 3 Enterprise 3.10:

  • Catalog format upgrade: the on-disk catalog automatically upgrades from format v2 to v3 on first 3.10 startup. Migration is one-way—back up your catalog before upgrading.
  • Automated backup and restore (beta)
  • Row-level deletions
  • User management (authentication and RBAC) — preview
  • Performance preview improvements

Backup and restore, row-level deletions, and the performance preview require the Enterprise storage engine upgrade (opt-in beta). Beta and preview features are subject to breaking changes and aren’t recommended for production use.

InfluxDB Docker latest tag changing to InfluxDB 3 Core

On September 15, 2026, the latest tag for InfluxDB Docker images will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments.

If using Docker to install and run InfluxDB, the latest tag will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments. For example, if using Docker to run InfluxDB v2, replace the latest version tag with a specific version tag in your Docker pull command–for example:

docker pull influxdb:2
