By default, the number of BTs is set to 200 BTs per application and 50 BTs per agent. After the first 50 agents per agent are registered, additional BTs discovered from traffic will flow to a virtual business transaction named All Other Traffic - tier_name.
If the overall BTs registered for the application are below 200, you can choose to increase the default value of BTs discovered per agent using the agent node property: max-business-transactions (link: https://docs.appdynamics.com/pages/viewpage.action?pageId=104015883#AppAgentNodeProperties(M)-max-bu...)
The maximum value allowed for this property is 200.
Note: Changing this setting can affect the resource consumption of your deployment. Before you change this setting, verify that your application environment and Controller can handle any increased resource requirements.
This will help to discover the important BTs and move it to the main list
