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, wherein the registering the new resource by generating the label to which is associated the system specific device identifier used by the new resource within the computing environment comprises: determining if all resources on which the new resource depends are already registered with an appropriate label; and in response to determining that not all resources on which the new resource depends are already registered: generating a new label to which is associated a system specific device identifier used by the new resource; and firing a reconciliation event with the new label and the associated system specific device identifier used by the new resource, the reconciliation event to be checked by a control instance.
