@events = $session->getClosure($object, $eventname[, $oneHop]);
The getClosure() function returns a list of symptoms associated with the problem or aggregate based on the relationships among instances defined in the Domain Manager.
The oneHop parameter is optional:
If it is omitted or passed as FALSE, the full list of problems that explain eventname, whether directly or indirectly, is returned.
If it is passed as TRUE, only those problems that directly list eventname among the events they explain are returned.
The function returns an array of array references with the format:
[ [ <classname::instancename>,<problemname> ], [ <classname::instancename>,<problemname> ], ... ]
@symptoms = $session->getClosure( "Router::gw1", "Down", 0 );
