The present disclosure relates to a method for handling an event message in a communications system. The method comprises receiving the event message and processing the event message using a pre-processing module of the communications system to determine if the event message is relevant for a management module of the communications system. Responsive to determining that the event message is relevant, the event message is tagged to generate a tagged event message, and the tagged event message is transmitted to the management module. Tagging the event comprises adding, to the event message, a model or pipeline label identifying a model or pipeline applied to the event message by the pre-processing module, a status identifier indicating a status of the event message following a process or set of processes performed by the model or pipeline, and an input identifier for identifying features or variables of the event message that were used as inputs to the model or pipeline.
