Re: [rules-users] Accumulate a on event combinations

Understood. Basically EventA is a connection lost event and EventB is a connection reopened event. In some situations the connection may be try several times and in this case we want to notify the system of a "pulsing" connection. So the ClosedConnectionEvent happens and then if a OpenConnectionEvent happens within 5 seconds we do nothing(if it's after 5 second we tell the system and a failover would occur). With that in mind I feel this will accomplish what I am looking for...thoughts? rule "Pulsing Connection" when accumulate($close:ConnectionEvent(connectionEventType == ConnectionEventType.CLOSE, $closedConnectionId:connectionInformationId) and ConnectionEvent(connectionInformationId== $closedConnectionId,connectionEventType == ConnectionEventType.OPEN, this after [0s,5s] $close); $count: count($close); $count>1) then //TODO: Disconnect and go to failover end laune wrote > > wrote: > >> I thought it was?
