The resource processor can be used to apply changes on resource attributes. Please refer to config.go for the config spec.

attributes represents actions that can be applied on resource attributes. See Attributes Processor for more details on supported attributes actions.

Supported Actions

• INSERT: Inserts the key/value to attributes when the key does not exist
• UPDATE: Updates an existing key with a value
• UPSERT: Performs insert or update depending on whether the key exists
• DELETE: Deletes the attribute
• HASH: Computes the SHA-256 hash of an existing value
• EXTRACT: Extracts values using a regular expression

Default Values

The default_value field can be used to specify a fallback value when the primary value source (e.g., attribute, or context value) is not available. This is useful for:

• Providing sensible defaults when attributes don't exist
• Ensuring the pipeline doesn't fail due to missing configuration

Examples:

processors:
  resource:
    attributes:
    # Basic example: set a fixed value
    - key: cloud.availability_zone
      value: "zone-1"
      action: upsert
    
    # Copy from another attribute
    - key: k8s.cluster.name
      from_attribute: k8s-cluster
      action: insert
    
    # Delete an attribute
    - key: redundant-attribute
      action: delete
    
    # Use default_value when source attribute doesn't exist
    - key: region
      from_attribute: cloud.region
      default_value: "us-east-1"
      action: insert
    
    # Use default_value when context value is not available
    - key: tenant_id
      from_context: "metadata.tenant"
      default_value: "default-tenant"
      action: upsert

Refer to config.yaml for detailed examples on using the processor.
