# Application Observability service overview annotations

You can enable Application Observability to display annotations in the service overview duration panel.

> Note
> 
> When you create annotations, they display only for the specific service that you designate.

## Create annotations

You must define the following tags to view annotations correctly:

- `service.name=name-of-service`: The service overview always adds the service name to the query
- `service.namespace=my-namespace`: If the service has a namespace, you must also add this tag
- `deployment.environment=name-of-environment`: If you selected an environment value in the service overview, you must also add the configured environment attribute. For example, `deployment.environment=oteldemo01`. If you have customized the name of the environment semantic attribute on the **Settings** tab of the **Configuration** page, then you should use that name instead. For example, `deployment.environment.name=oteldemo01`.

The following example shows how to create service view annotations:

  "tags":["service.name=cartservice","service.namespace=oteldemo01"],

}
```

## Enable or disable service overview annotations

You can enable or disable annotations from the **Settings** tab on the **Configuration** page under the **Service overview annotations** section.
