The default behavior is for the agent to auto-launch the Java proxy, where proxyAutolaunchDisabled is false

If you allow the agent to auto-launch and you have one Node.js process per machine, the agent will automatically use the default port values if they are available. In this case, you do not have to configure these settings.

If the default ports are not available, configure these settings to ports that are available in the require statement in the require statement.

If you have multiple Node.js processes on a single machine each reporting to its own proxy, each process needs its own set of ports. In this case, configure unique settings for all three ports in the require statement for each process.
