Hi Matt, For saas controllers, you will not have access to controller logs. I did a quick validation on your saas controller https://548.saas.appdynamics.com/controller. It looksl you have installed machine agent and not app agent. Business Transaction Discovery is supported on Java + .NET agents only and not on machine agents. Please find supporting screenshot attached.  More details on transaction discovery tool can be found on below link https://docs.appdynamics.com/display/PRO42/Using+the+Transaction+Discovery+Tool We hope it clarifes your doubt.  Please keep us posted.  Thanks, Preet ...
