METHOD, SYSTEM AND COMPUTER PROGRAM FOR MONITORING COMPONENTS IN A SERVICE FRAMEWORK

摘要

A solution (A1-A12) is proposed for monitoring usage of bundles (240) in the OSGi environment. For this purpose, an event notification interface (410) of the OSGi environment is exploited. Particularly, each event (A2-A5) relating to a change of state of a bundle (such as its addition, removal, starting and stopping) is detected (A6-A9) by an auxiliary bundle (240a) - which previously subscribed (A1) to the event notification interface. The auxiliary bundle can then forward (A10) the detected events to a licensing agent, which identifies (A11-A12) the bundle by means of a software catalogue (420). In this way, the desired result is achieved without requiring any instrumentation of the bundles to be monitored.
