A solution is proposed for monitoring usage of bundles in the OSGi environment. For this purpose, an event notification interface of the OSGi environment is exploited. Particularly, each event relating to a change of state of a bundle (such as its addition, removal, starting and stopping) is detected by an auxiliary bundle&#x2014;which previously subscribed to the event notification interface. The auxiliary bundle can then forward the detected events to a licensing agent, which identifies the bundle by means of a software catalogue. In this way, the desired result is achieved without requiring any instrumentation of the bundles to be monitored.

The invention proposes a solution for controlling logical guest machines, such as virtual machines or logical partitions, in a system management application (and especially in a licensing application). There is provided an enabler running in a physical host machine implementing the guest machines or in a corresponding console; this enabler gathers information relating to the hardware configuration of the host machine (which information is not available inside the guest machine). The hardware configuration information is then passed to a licensing agent of the guest machine; for example, the desired result may be achieved by means of dedicated variables or registry keys that are accessible without providing any user credentials. The licensing agent directly gathers other information, for example, indicating the software products that are used by the guest machine. The available information is then transmitted by the licensing agent to a runtime server for the correct management of the guest machine.

Metering execution of interpreted programs on a data processing system is accomplished. An interpreted program requests a service to an interpreter running the interpreted program. The interpreter invokes a native external function for implementing the service. The invocation of the external function is intercepted. The interpreted program identified according to the external function by accessing a catalogue which associates native functions with interpreted programs. A license management operation is performed according to the identified interpreted program.
