discovery.triton discovers Triton Container Monitors and exposes them as targets.


discovery.triton "LABEL" {
	account    = ACCOUNT
	dns_suffix = DNS_SUFFIX
	endpoint   = ENDPOINT


The following arguments are supported:

accountstringThe account to use for discovering new targets.yes
rolestringThe type of targets to discover."container"no
dns_suffixstringThe DNS suffix that is applied to the target.yes
endpointstringThe Triton discovery endpoint.yes
groupslist(string)A list of groups to retrieve targets
portintThe port to use for discovery and metrics scraping.9163no
refresh_intervaldurationThe refresh interval for the list of targets.60sno
versionintThe Triton discovery API version.1no

role can be set to:

  • "container" to discover virtual machines (SmartOS zones, lx/KVM/bhyve branded zones) running on Triton
  • "cn" to discover compute nodes (servers/global zones) making up the Triton infrastructure

groups is only supported when role is set to "container". If omitted all containers owned by the requesting account are scraped.


The following blocks are supported inside the definition of discovery.triton:

tls_configtls_configTLS configuration for requests to the Triton

tls_config block

ca_pemstringCA PEM-encoded text to validate the server

key_filestringKey file for client

The following pairs of arguments are mutually exclusive and can’t both be set simultaneously:

  • ca_pem and ca_file
  • cert_pem and cert_file
  • key_pem and key_file

When configuring client authentication, both the client certificate (using cert_pem or cert_file) and the client key (using key_pem or key_file) must be provided.

When min_version is not provided, the minimum acceptable TLS version is inherited from Go’s default minimum version, TLS 1.2. If min_version is provided, it must be set to one of the following strings:

  • "TLS10" (TLS 1.0)
  • "TLS11" (TLS 1.1)
  • "TLS12" (TLS 1.2)
  • "TLS13" (TLS 1.3)

Exported fields

The following fields are exported and can be referenced by other components:

targetslist(map(string))The set of targets discovered from the Triton API.

When role is set to "container", each target includes the following labels:

  • __meta_triton_groups: The list of groups belonging to the target joined by a comma separator.
  • __meta_triton_machine_alias: The alias of the target container.
  • __meta_triton_machine_brand: The brand of the target container.
  • __meta_triton_machine_id: The UUID of the target container.
  • __meta_triton_machine_image: The target container’s image type.
  • __meta_triton_server_id: The server UUID the target container is running on.

When role is set to "cn" each target includes the following labels:

  • __meta_triton_machine_alias: The hostname of the target (requires triton-cmon 1.7.0 or newer).
  • __meta_triton_machine_id: The UUID of the target.

Component health

discovery.triton is only reported as unhealthy when given an invalid configuration. In those cases, exported fields retain their last healthy values.

Debug information

discovery.triton does not expose any component-specific debug information.

Debug metrics

discovery.triton does not expose any component-specific debug metrics.


discovery.triton "example" {
	account    = TRITON_ACCOUNT
	dns_suffix = TRITON_DNS_SUFFIX
	endpoint   = TRITON_ENDPOINT

prometheus.scrape "demo" {
	targets    = discovery.triton.example.targets
	forward_to = [prometheus.remote_write.demo.receiver]

prometheus.remote_write "demo" {
	endpoint {

		basic_auth {
			username = USERNAME
			password = PASSWORD

Replace the following:

  • TRITON_ACCOUNT: Your Triton account.
  • TRITON_DNS_SUFFIX: Your Triton DNS suffix.
  • TRITON_ENDPOINT: Your Triton endpoint.
  • PROMETHEUS_REMOTE_WRITE_URL: The URL of the Prometheus remote_write-compatible server to send metrics to.
  • USERNAME: The username to use for authentication to the remote_write API.
  • PASSWORD: The password to use for authentication to the remote_write API.
