Add fields

The add_fields processor adds additional fields to the event. Fields can be scalar values, arrays, dictionaries, or any nested combination of these. By default the fields that you specify will be grouped under the fields sub-dictionary in the event. To group the fields under a different sub-dictionary, use the target setting. To store the fields as top-level fields, set target: ''.

target
(Optional) Sub-dictionary to put all fields into. Defaults to fields.
fields
Fields to be added.

For example, this configuration:

processors:
- add_fields:
    target: project
    fields:
      name: myproject
      id: '574734885120952459'

Adds these fields to any event:

{
  "project": {
    "name": "myproject",
    "id": "574734885120952459"
  }
}
