Unique event identification

Embodiments of methods, systems and storage medium associated with generating and storing a unique event identifier (UEID) associated with a type of an event of a module of a computing system are disclosed herein. Specifically, a centralized UEID storage may include one or more event nodes configured to associate a UEID with a type of an event handled by or occurring at an owner module. The centralized UEID storage may be further configured to associate, using the UEID, the type of the event with one or more callback functions of one or more client modules. Upon occurrence of the type of the event, the callback functions may be identified and invoked using the UEID.
