Method Detail

getKind

public abstract ServiceDownEvent.EventKind getKind()

Service down events can be member down, composite down, or both. This method reports which this is. A member down means just a single member instance of the service is down. A composite down means that all member instances of the service are down and so the service itself is down. A single event can report both the last member down and the composite down. These may also come as separate events.

Returns:

the event kind.

getServiceName

public abstract java.lang.String getServiceName()

Returns:

the service name.

getDatabaseUniqueName

public abstract java.lang.String getDatabaseUniqueName()

Returns:

the database unique name.

getReason

public abstract ServiceDownEvent.Reason getReason()

Returns:

the reason for the service going down.

getServiceMemberEvent

public abstract ServiceDownEvent.ServiceMemberEvent getServiceMemberEvent()

Return the service member subevent information if this is a service member event. Returns null if this kind is COMPOSITE. A service event can be either a member or composite event, or both.

Returns:

a ServiceMemberEvent or null.
