Splunk AppDynamics for OpenTelemetry™ ingests and aggregates traces into Business Transaction flow metrics in the Controller UI. A trace represents an end-to-end request which can be made up of one or multiple spans. Each span represents one event within a component in the application triggered in the trace. The Business Transaction represents the entire graph of all traces sharing the same root span and visualizes how traces flow between services.

Application Dashboard

The Application Flow Map is a dynamic visual representation of your monitored environment's components and activities. Monitored services using OpenTelemetry¹ are represented by the OpenTelemetry telescope icon. For a list of supported language in the flow map, see Supported Languages.

To view OpenTelemetry data on your Application Dashboard:

1. Go to your OpenTelemetry-enabled application.
2. Click Application Dashboard > Dashboard.

After instrumentation, it may take up to five minutes for data to populate in the Controller UI.

If you want to look at data from just one tier, click on a tier in the Flow Map. You will be redirected to the Tiers & Nodes Flow Map which will populate with data for that OpenTelemetry tier.

See Learn how to navigate and customize flow maps.

Tiers & Nodes

On Tiers & Nodes, you can view a list of all tiers in an application. The tiers represent the services (defined by service.name) that were encountered by the ingested traces. To investigate specific tiers, double-click on a tier name and see a new flow map that is updated with tier-specific data.

Business Transactions

On Business Transactions, the names of the Business Transactions are derived from the name of the first span of each trace (also known as the root span). The health status, response time, number of calls, and other metrics are reported for the Business Transaction.
