Riemann Output Plugin

This plugin writes to Riemann via TCP or UDP.

Global configuration options

In addition to the plugin-specific configuration settings, plugins support additional global and plugin configuration settings. These settings are used to modify metrics, tags, and field or create aliases and configure ordering, etc. See the CONFIGURATION.md for more details.

Configuration

# Configuration for Riemann to send metrics to
[[outputs.riemann]]
  ## The full TCP or UDP URL of the Riemann server
  url = "tcp://localhost:5555"

  ## Riemann event TTL, floating-point time in seconds.
  ## Defines how long that an event is considered valid for in Riemann
  # ttl = 30.0

  ## Separator to use between measurement and field name in Riemann service name
  ## This does not have any effect if 'measurement_as_attribute' is set to 'true'
  separator = "/"

  ## Set measurement name as Riemann attribute 'measurement', instead of prepending it to the Riemann service name
  # measurement_as_attribute = false

  ## Send string metrics as Riemann event states.
  ## Unless enabled all string metrics will be ignored
  # string_as_state = false

  ## A list of tag keys whose values get sent as Riemann tags.
  ## If empty, all Telegraf tag values will be sent as tags
  # tag_keys = ["telegraf","custom_tag"]

  ## Additional Riemann tags to send.
  # tags = ["telegraf-output"]

  ## Description for Riemann event
  # description_text = "metrics collected from telegraf"

  ## Riemann client write timeout, defaults to "5s" if not set.
  # timeout = "5s"

Required parameters

  • url: The full TCP or UDP URL of the Riemann server to send events to.

Optional parameters

  • ttl: Riemann event TTL, floating-point time in seconds. Defines how long that an event is considered valid for in Riemann.
  • separator: Separator to use between measurement and field name in Riemann service name.
  • measurement_as_attribute: Set measurement name as a Riemann attribute, instead of prepending it to the Riemann service name.
  • string_as_state: Send string metrics as Riemann event states. If this is not enabled then all string metrics will be ignored.
  • tag_keys: A list of tag keys whose values get sent as Riemann tags. If empty, all Telegraf tag values will be sent as tags.
  • tags: Additional Riemann tags that will be sent.
  • description_text: Description text for Riemann event.

Example Events

Riemann event emitted by Telegraf with default configuration:

#riemann.codec.Event{
:host "postgresql-1e612b44-e92f-4d27-9f30-5e2f53947870", :state nil, :description nil, :ttl 30.0,
:service "disk/used_percent", :metric 73.16736001949994, :path "/boot", :fstype "ext4", :time 1475605021}

Telegraf emitting the same Riemann event with measurement_as_attribute set to true:

#riemann.codec.Event{ ...
:measurement "disk", :service "used_percent", :metric 73.16736001949994,
... :time 1475605021}

Telegraf emitting the same Riemann event with additional Riemann tags defined:

#riemann.codec.Event{
:host "postgresql-1e612b44-e92f-4d27-9f30-5e2f53947870", :state nil, :description nil, :ttl 30.0,
:service "disk/used_percent", :metric 73.16736001949994, :path "/boot", :fstype "ext4", :time 1475605021,
:tags ["telegraf" "postgres_cluster"]}

Telegraf emitting a Riemann event with a status text and string_as_state set to true, and a description_text defined:

#riemann.codec.Event{
:host "postgresql-1e612b44-e92f-4d27-9f30-5e2f53947870", :state "Running", :ttl 30.0,
:description "PostgreSQL master node is up and running",
:service "status", :time 1475605021}
