Enable Dual Signal mode (Nodejs)

For Nodejs Agent 25.8.0 or higher:

ModeBehavior
Dual

The agent works in Dual Signal mode. It uses:

  • AppD specific instrumentation to collect APM data for an AppD controller.
  • OTel specific instrumentation to generate OTel signals and sends them to a collector.
AppD
  • The agent uses AppD specific instrumentation only and sends data to an AppD controller.
  • The OTel specific instrumentation is not applied. OTel signals are not generated.

You can configure this mode by using one of the following methods:

  • Environmental variable: EXPORT AGENT_DEPLOYMENT_MODE=dual
  • Application configuration: 
    appd.profile({

````agent_deployment_mode: `appd`,       
````
},
