Enable Dual Signal mode

To enable this mode:
  • set Java command line option -Dappdynamics.opentelemetry.enabled=true or -Dagent.deployment.mode=dual or.
  • set environment variable AGENT_DEPLOYMENT_MODE=dual.

When the Java Agent runs in Dual Signal mode, the agent automatically adds the following attributes to spans which correspond to Business Transaction start. In most cases, these attributes will be root spans for traces:

  • appd.app.name
  • appd.bt.name
  • appd.request.guid
  • appd.tier.name (this attribute can also appear in the middle of a trace whenever the tier changes)

Also, when possible, Splunk AppDynamics snapshots captured in Dual Signal mode will provide the corresponding TraceId under the Data Collectors tab. For more information on sending traces and metrics to local Open Telemetry collector or directly to Splunk Observability cloud, see Configure Open Telemetry.
