Splunk Agent Observability supports annotations on Sessions, Traces, and Spans. Use the main menu to select an Agent Stream, then select a trace. The **Messages** tab allows you to submit annotations, and highlights available annotations with a dot indicator. Annotations For each project, users with the necessary permissions can configure one or more of these annotation types: * **Categories**: Enable annotators to select one or more designated categories * **Score**: Enable annotators to select a number between 0 and a max score * **Star**: Enable annotators to rate from 1 to 5 stars * **Text**: Enable annotators to provide freeform text * **Thumbs Up & Down**: Enable annotators to rate a like or dislike The following roles have permissions to configure annotations: organization admins, project owners, or project editors. The minimum permissions for creating annotations are: organization users, and project annotators. Read-only or viewer roles cannot submit annotations. ## Annotation Queues Splunk Agent Observability's Annotation Queues enable teams to organize and scale human feedback by grouping project logs (sessions, traces, and spans) for structured review by subject matter experts. Use the main menu to select **Annotation Queues** to access the page. Annotation Queue in the UI
