> MonitorActivity processor, when the node disconnects from the cluster, might still emit "inactive" message. This can happen when the scope is set to cluster level monitoring and the given node cannot reach shared state but has information only based on the local activity. This might lead to false inactivity alert, so it is desirable to prevent reporting until the node is disconnected and reconcile state after reconnection.
