org.yamcs.alarms.AlarmServer<EventId,Db.Event>

org.yamcs.alarms.EventAlarmServer

All Implemented Interfaces:

com.google.common.util.concurrent.Service

public class EventAlarmServer
extends AlarmServer<EventId,Db.Event>

Handles alarms for events. These are generated whenever an event with a severity level different than INFO is received.

The events having the same (source, type) are considered to be part of the same alarm.

In the future we could implement some additional options like configuring events that never throw alarms or adding the possibility to configure the minViolations for each event id (= event source+ type).
