Hello Boyka You're currently not attaching a debugger to the agent VM. Currently you have one debugger attached to the master JVM, but none to the agent JVM.
I'm not familiar with Eclipse itself but basically you want to create a Remote configuration that will attach to the agent VM (on port 8765 according to the configuration you sent). Look into the launch configuration in Eclipse, you should find something like Remote or Remote Java Application. One way to quickly check the attaching works is to change suspend=n by suspend=y when launching your agent. This way the JVM will wait for the debugger to attach to proceed and you'll know that you attached properly. Hope this helps.
