Zack Zatkin-Gold 61be19b1f0 Fix telegraf example arguments (#2788)
Many of the examples provided within documentation are using a single
dash for the command line arguments, but the telegraf executable
explicitly has two dashes.

There are also some inconsistencies with the ordering of the command
line argument examples.  I've ordered them so that the examples will
show: config, config-directory, input-filter, test

Telegraf Input Plugin: Consul

This plugin will collect statistics about all helath 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]]
  ## Most of these values defaults to the one configured on a Consul's agent level.
  ## Optional Consul server address (default: "")
  # address = ""
  ## Optional URI scheme for the Consul server (default: "")
  # scheme = ""
  ## Optional ACL token used in every request (default: "")
  # token = ""
  ## Optional username used for request HTTP Basic Authentication (default: "")
  # username = ""
  ## Optional password used for HTTP Basic Authentication (default: "")
  # password = ""
  ## Optional data centre to query the health checks from (default: "")
  # datacentre = ""

Tags:

  • node: on which node check/service is registered on
  • service_name: name of the service (this is the service name not the service ID)
  • check_id

Fields:

  • check_name
  • service_id
  • status
  • passing
  • critical
  • warning

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.

Example output

$ telegraf --config ./telegraf.conf --input-filter consul --test
