Construct a new VmStatusChangeEvent instance.
Params:
  • host – the MonitoredHost that is the source of the event.
  • active – the set of currently active Java Virtual Machines
  • started – the set of Java Virtual Machines started since the last event.
  • terminated – the set of Java Virtual Machines terminated since the last event.

Return the set of currently active Java Virtual Machines. The set contains an Integer object holding the lvmid for each active Java Virtual Machine on the MonitoredHost.
Returns:Set - a set of Integer objects containing the lvmid of each active Java Virtual Machine on the host. If there are no active Java Virtual Machines on the host, an empty Set is returned.

Return the set of Java Virtual Machines started since the last event notification. The set contains an Integer object holding the lvmid for each Java Virtual Machine started on the MonitoredHost since the last event notification.
Returns:Set - a set of Integer objects containing the lvmid of each Java Virtual Machine started on the host. If no Java Virtual Machines were recently started on the host, an empty Set is returned.
