= Attributes Processor
|
|
|
|
[role="_abstract"]
|
|
The Attributes Processor can modify attributes of a span, log, or metric. You can configure this processor to filter and match input data and include or exclude such data for specific actions.
|
|
|
|
This processor operates on a list of actions, executing them in the order specified in the configuration. The following actions are supported:
|
|
|
|
Insert:: Inserts a new attribute into the input data when the specified key does not already exist.
|
|
|
|
Update:: Updates an attribute in the input data if the key already exists.
|
|
|
|
Upsert:: Combines the insert and update actions: Inserts a new attribute if the key does not exist yet. Updates the attribute if the key already exists.
|
|
|
|
Delete:: Removes an attribute from the input data.
|
|
|
|
Hash:: Hashes an existing attribute value as SHA1.
|
|
|
|
Extract:: Extracts values by using a regular expression rule from the input key to the target keys defined in the rule. If a target key already exists, it is overridden similarly to the Span Processor's `to_attributes` setting with the existing attribute as the source.
|
|
|
|
Convert:: Converts an existing attribute to a specified type.
