Mapping application dependencies in a computer network

This application is directed to a mapping method performed at a computational machine in a linear communication orbit. The computational machine receives an application definition the linear communication orbit. The application definition specifies criteria for establishing whether the computational machine executes a specified application, a component of the specified application, or communicate with another node executing the specified application or a component of the specified application. While a plurality of events are occurring locally at the computational machine, the computational machine identifies one or more operations meeting the application definition in real-time. The identified one or more operations meeting the application definition, and associated metadata are stored in a local mapping database of the computational machine and returned to the server system through the linear communication orbit in response to a map request received through the linear communication orbit.
