Filter by specifying a specific notifier name, or subscriber object to show only lines where this object is a subscriber.
If the -global flag is specified, print a list of added global notifier subscribers.
In this case each entry in the output contains: notifier name, subscriber object (or NIL if no subscriber) and one-shot status (TRUE if and only if the notifier was added with SIM_add_global_notifier_once).
If the -global flag is not specified, print a list of added notifier subscribers on object, or subscribers on all objects, if the object parameter is omitted.
In this case each entry in the output contains: notifier object, notifier name, notifier description, and the subscriber object (or NIL if no subscriber).
