I guess you want to instrument Appium scripts to send measurements from one or a few Devices to NeoLoad while the load is generated at protocol level by NeoLoad so that you can correlate the two views: the server response time and the action time on the device.

In short: you need to write your Appium script outside NeoLoad, insert measurement calls, and make sure NeoLoad launch the Appium execution through the Java or Command Line advanced action.
