Edge Delta Datadog Mapper

Overview

The Datadog Mapper node applies mappings to create a new payload for the Datadog event endpoint. The output of this node can only be received by the Datadog output node. This node can ingest a log type or a custom type. There are some restrictions around what types of values can populate certain fields, for example the “message” field of the Datadog payload can only take string values, JSON strings, and JSON/maps.

Most of the fields in the schema can be customized, except “event” and “index”. If not customized, it will use the default value:

• Message: item["body"]
• Tags: item["attributes"]
• Source: item["resource"]["src_type"]
• Souce Name: item["resource"]["__src_name"]
• Host: item["resource"]["host.name"]
• Service:item["resource"]["__logical_source"]
• Level: INFO
• DataType: Log

If the specified field is missing from the incoming item, an empty string will be used as default value.

A timestamp is not defined because the default Datadog timestamp is used. You can select a field from the payload to use in Datadog using a remapper.

Required Parameters

name

A descriptive name for the node. This is the name that will appear in Visual Pipelines and you can reference this node in the yaml using the name. It must be unique across all nodes. It is a yaml list element so it begins with a - and a space followed by the string. It is a required parameter for all nodes.

nodes:
  - name: <node name>
    type: <node type>

type: ​​datadog_mapper

The type parameter specifies the type of node being configured. It is specified as a string from a closed list of node types. It is a required parameter.

nodes:
  - name: <node name>
    type: <node type>

dd_message

The dd_message parameter is used to define which input item to use for the message field in the output Datadog payload. It is specified with CEL and you can use CEL macros. It is required.

nodes:
  - name: datadog_payload_mapping_example
    type: ​​datadog_mapper
    dd_message: item["body""]

dd_service

The dd_service parameter is used to define which input item to use for the service field in the output Datadog payload. It is specified with CEL and you can use CEL macros. It is required.

nodes:
  - name: datadog_payload_mapping_example
    type: ​​datadog_mapper
    dd_message: item["body""]
    dd_service: item["resource"]["__logical_source"]

dd_source

The dd_source parameter is used to define which input item to use for the ddsource field in the output Datadog payload. It is specified with CEL and you can use CEL macros. It is required.

nodes:
  - name: datadog_payload_mapping_example
    type: ​​datadog_mapper
    dd_message: item["body""]
    dd_source: item["resource"]["__src_name"]

dd_tags

The dd_tags parameter is used to define which input item to use for the “ddtags” field in the output Datadog payload. It is specified with CEL and you can use CEL macros. It is required.

nodes:
  - name: datadog_payload_mapping_example
    type: ​​datadog_mapper
