Configuration Table

Parameter	Type	Default	Description
telemetry_types	`telemetrySelector`	`["Logs", "Metrics", "Traces"]`	The list of telemetry types the processor will act on.
deleted_values	`enums`	`["Null Values"]`	List of values types to delete. May include “Null Values”, “Empty Lists”, and “Empty Maps”. Enabling “Null Values” will remove both empty (zero-length) strings and entirely empty values. Enabling “Empty Lists” will delete empty (no element) list values. Enabling “Empty Maps” will delete empty (no key) map values.
exclude_resource_keys	`strings`	`[]`	List of resource keys to exclude from deletion.
exclude_attribute_keys	`strings`	`[]`	List of attribute keys to exclude from deletion.
exclude_body_keys	`string`	`[]`	List of body keys to exclude from deletion.
empty_string_values	`strings`	`[]`	List of string values that are considered “empty”. String fields will be deleted if they match any of the strings in this list.

Example Configuration
