Add/set key/value action
The add/set key/value action is used in processing rules to add the same key/value pair to every record that passes through your pipeline. If a record contains a matching key, this action overwrites that key's associated value with the value you specify.
Configuration parameters
- Key: Required. The key to add to each record. You can use record accessor syntax to add or overwrite keys nested inside a parent object.
- Value: Required. The value to associate with your key. This value is identical for every instance of Key.
- Comment: A description for the action's function that is displayed in the Actions list.
Example
Using the add/set key/value action lets you add identifying information to events, such as including the source from which they originate or their associated user action.
