How can I set the Controller's Port using Environmentvalriable?

whether it will be like below.

{

"controller": {
"host": "%APPDYNAMICS.CONTROLLER.HOSTNAME%",
"port": %APDDYNAMICS.CONTROLLER.PORT%,
}
}

I don't think it's correct. Is there any way we can inject the port environment variable.

I used https://docs.appdynamics.com/display/PRO45/AppDynamicsConfig.json+File
Also the host value which I was reading from the Environment variable, whether it's correct?

"host": "%APPDYNAMICS.CONTROLLER.HOSTNAME%",

You can set the environment variable APPDYNAMICS_CONTROLLER_HOST_NAME in the Environment variables of the machine (or process) like any other environment variable. This will override the JSON values that are set.

Linux
export APPDYNAMICS_CONTROLLER_HOST_NAME=yourcontroller

Windows

setx APPDYNAMICS_CONTROLLER_HOST_NAME=yourcontroller

Note: setx is part of Windows 2008 and higher and will take effect in new sessions / command prompts. It is persistant unlike the set command.
