@events =  $session->getCauses( $objectname, $event [, $oneHop] );

The getCauses() function returns a list of problems that cause an event.

The function arguments are class, instance (possibly combined into one, for example, SM_System::SM-System), and event. The function returns the problems that cause the event 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> ],
