Event and Alarm
Management Objects
EventManager
is the service interface for
working with the event infrastructure.
Event
subtypes define the events that the system generates. See
Event Data Objects
and
Creating Custom Events.
EventHistoryCollector
allows you to monitor
events. You can create a filter to limit the number of events your code
retrieves. You can monitor both system events and your own events. See
Using an EventHistoryCollector.
The
AlarmManager
is the service
interface for creating, setting, and managing alarms. You create an alarm,
specifying trigger conditions and the action to take. When the conditions
defined for the
Alarm
occur on the system, the
Action
specified for the alarm
starts. The alarm also generates an
Event
that you can retrieve with
an
EventHistoryCollector
.
