1. A computer implemented method for displaying components assigned to events produced by resources, the resources being executed within a computing environment, the method comprising: registering a new resource by generating a label to which is associated a system specific device identifier used by the new resource within the computing environment; storing in a mapping table the generated label identifying the registered new resource together with the new resource's associated system specific device identifier; updating the mapping table by associating to the generated label any other system specific device identifier used by the new resource within the computing environment; receiving events produced by resources when being executed within the computing environment, each event being associated with a list of labels for the resources relevant for the generation of that event; and maintaining a tag cloud comprising different tags, the different tags comprising labels for the resources associated with the received events to be displayed as components.
