Separate agent configuration into its own pages
I apologize in advance for the rather long PR, but unfortunately there
is not an easy way to break this up into smaller chunks. This separates
the agent configuration into smaller, more consumable pieces just like
the job specification.

telemetry Stanza

Placement **telemetry**

The telemetry stanza configures Nomad's publication of metrics and telemetry to third-party systems.

telemetry {
  public_allocation_metrics = true
  publish_node_metrics      = true
}

This section of the documentation only covers the configuration options for telemetry stanza. To understand the architecture and metrics themselves, please see the Nomad telemetry documentation.

telemetry Parameters

Due to the number of configurable parameters to the telemetry stanza, parameters on this page are grouped by the telemetry provider.

Common

The following options are available on all telemetry configurations.

  • disable_hostname (bool: false) - Specifies if gauge values should be prefixed with the local hostname.

  • publish_allocation_metrics (bool: false) - Specifies if Nomad should publish runtime metrics of allocations.

  • publish_node_metrics (bool: false) - Specifies if Nomad should publish runtime metrics of nodes.

statsite

These telemetry parameters apply to statsite.

  • statsite_address (string: "") - Specifies the address of a statsite server to forward metrics data to.
telemetry {
  statsite_address = "statsite.company.local:8125"
}

statsd

These telemetry parameters apply to statsd.

  • statsd_address (string: "") - Specifies the address of a statsd server to forward metrics to.
telemetry {
  statsd_address = "statsd.company.local:8125"
}

datadog

These telemetry parameters apply to DataDog statsd.

  • datadog_address (string: "") - Specifies the address of a DataDog statsd server to forward metrics to.
telemetry {
  datadog_address = "dogstatsd.company.local:8125"
}

circonus

These telemetry parameters apply to Circonus.

  • circonus_api_token (string: "") - Specifies a valid Circonus API Token used to create/manage check. If provided, metric management is enabled.

  • circonus_api_app (string: "nomad") - Specifies a valid app name associated with the API token.

  • circonus_api_url (string: "https://api.circonus.com/v2") - Specifies the base URL to use for contacting the Circonus API.

  • circonus_submission_interval (string: "10s") - Specifies the interval at which metrics are submitted to Circonus.

  • circonus_submission_url (string: "") - Specifies the check.config.submission_url field, of a Check API object, from a previously created HTTPTRAP check.

  • circonus_check_id (string: "") - Specifies the Check ID (not check bundle) from a previously created HTTPTRAP check. The numeric portion of the check._cid field in the Check API object.

  • circonus_check_force_metric_activation (bool: false) - Specifies if force activation of metrics which already exist and are not currently active. If check management is enabled, the default behavior is to add new metrics as they are encountered. If the metric already exists in the check, it will not be activated. This setting overrides that behavior.

  • circonus_check_instance_id (string: "<hostname>:<application>") - Serves to uniquely identify the metrics coming from this instance. It can be used to maintain metric continuity with transient or ephemeral instances as they move around within an infrastructure. By default, this is set to hostname:application name (e.g. "host123:nomad").

  • circonus_check_search_tag (string: <service>:<application>) - Specifies a special tag which, when coupled with the instance id, helps to narrow down the search results when neither a Submission URL or Check ID is provided. By default, this is set to service:app (e.g. "service:nomad").

  • circonus_broker_id (string: "") - Specifies the ID of a specific Circonus Broker to use when creating a new check. The numeric portion of broker._cid field in a Broker API object. If metric management is enabled and neither a Submission URL nor Check ID is provided, an attempt will be made to search for an existing check using Instance ID and Search Tag. If one is not found, a new HTTPTRAP check will be created. By default, this is a random Enterprise Broker is selected, or, the default Circonus Public Broker.

  • circonus_broker_select_tag (string: "") - Specifies a special tag which will be used to select a Circonus Broker when a Broker ID is not provided. The best use of this is to as a hint for which broker should be used based on where this particular instance is running (e.g. a specific geo location or datacenter, dc:sfo).
