Enable Dual Signal mode

To enable this mode, set one of the following:
  • For Java Agent 25.7.0 or higher, use the above system properties or set environment variable AGENT_DEPLOYMENT_MODE=dual.
  • For Java Agent 25.6.0 or higher, set -Dappdynamics.opentelemetry.enabled=true or -Dagent.deployment.mode=dual.

In Dual Signal mode, the agent 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.
