OpenTelemetry is a collection of tools, APIs, and SDKs used to instrument, generate, collect, and export telemetry data (metrics, logs, and traces) to help you analyze software performance and behavior.

Splunk AppDynamics provides an OpenTelemetry-compatible backend to ingest OpenTelemetry trace data using OpenTelemetry components. The ingested data is processed by the Splunk AppDynamics backend and displayed in the Controller UI. This service is referred to as Splunk AppDynamics for OpenTelemetry.
