       Automatic discovery is a feature of the Splunk distribution of the OpenTelemetry Collector that identifies the applications running in your environment and sends telemetry data from them to Splunk Application Performance Monitoring (APM). The Collector configures an application-specific receiver that collects data from an endpoint exposed on the source application. Automatic discovery is available for applications written in Java, Node.JS, and .NET. For more information, see :Ref:`discovery_mode`.
 
    automatic instrumentation
-      Automatic instrumentation uses an :term:`agent` of the Splunk distribution of the OpenTelemetry Collector to instrument your source application for the export of telemetry data without requiring the end user to modify the application code. The agent configures the source application to export data in a supported format to an OTLP endpoint, on either an OTLP receiver or the Splunk Observability Cloud back end. Automatic instrumentation is available for applications written in Java, Node.js, .NET, Go, Python, Ruby, and PHP and automatically collects telemetry data for code written using supported libraries in each language. For more information, see :ref:`get-started-application`.
