Consul Input Plugin

This plugin will collect statistics about all health checks registered in the Consul. It uses Consul API to query the data. It will not report the telemetry but Consul can report those stats already using StatsD protocol if needed.

Configuration

# Gather health check statuses from services registered in Consul
[[inputs.consul]]
  ## Consul server address
  # address = "localhost:8500"

  ## URI scheme for the Consul server, one of "http", "https"
  # scheme = "http"

  ## Metric version controls the mapping from Consul metrics into
  ## Telegraf metrics. Version 2 moved all fields with string values
  ## to tags.
  ##
  ##   example: metric_version = 1; deprecated in 1.16
  ##            metric_version = 2; recommended version
  # metric_version = 1

  ## ACL token used in every request
  # token = ""

  ## HTTP Basic Authentication username and password.
  # username = ""
  # password = ""

  ## Data center to query the health checks from
  # datacenter = ""

  ## 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 = true

  ## Consul checks' tag splitting
  # When tags are formatted like "key:value" with ":" as a delimiter then
  # they will be splitted and reported as proper key:value in Telegraf
  # tag_delimiter = ":"

Metrics

metric_version = 1
  • consul_health_checks
    • tags:
      • node (node that check/service is registered on)
      • service_name
      • check_id
    • fields:
      • check_name
      • service_id
      • status
      • passing (integer)
      • critical (integer)
      • warning (integer)
metric_version = 2
  • consul_health_checks
    • tags:
      • node (node that check/service is registered on)
      • service_name
      • check_id
      • check_name
      • service_id
      • status
    • fields:
      • passing (integer)
      • critical (integer)
      • warning (integer)

passing, critical, and warning are integer representations of the health check state. A value of 1 represents that the status was the state of the the health check at this sample. status is string representation of the same state.
