If you have an application that is monitored with Splunk AppDynamics Java, .NET, or Node.js Agents, you can instrument Splunk AppDynamics agents in your application to report both OpenTelemetry span data and data. When instrumented, the agents will generate OpenTelemetry span data from HTTP entry and exit requests. The Splunk AppDynamics correlation header is injected inside the OpenTelemetry baggage header, which results in the correlation with Business Transactions through intersecting OpenTelemetry nodes.

For example, the diagram above demonstrates how OpenTelemetry data is reported when an Splunk AppDynamics Java Agent is enabled for OpenTelemetry. The Java Agent sends data to the Controller and OpenTelemetry spans to the OpenTelemetry Collector. The Collector then sends the received spans to the Splunk AppDynamics OpenTelemetry Service via OTLP/HTTP(s). The Splunk AppDynamics OpenTelemetry Service consolidates the spans into traces and maps traces to Business Transactions that are registered with the Controller. The Controller UI displays both the data from the Agent and the OpenTelemetry data from the Splunk AppDynamics OpenTelemetry Service.
