             Summary: Add attribute to model which will indicate that backup is synchronized with live server 
                 Key: WFLY-9699
                 URL: https://issues.jboss.org/browse/WFLY-9699
             Project: WildFly
          Issue Type: Feature Request
          Components: JMS
    Affects Versions: 10.0.0.Final
            Reporter: Miroslav Novak
            Assignee: Jeff Mesnil
            Priority: Critical


If HA is configured with replicated journal then it takes some time to backup to synchronize with live server.  Once backup is in sync with live then following information appears in server.log:
{code}
13:20:00,739 INFO  [org.apache.activemq.artemis.core.server] (Thread-3 (ActiveMQ-client-netty-threads-457000966)) AMQ221024: Backup server ActiveMQServerImpl::serverUUID=bc015b34-fd73-11e5-80ca-1b35f669abb8 is synchronized with live-server.
13:20:01,500 INFO  [org.apache.activemq.artemis.core.server] (Thread-2 (ActiveMQ-server-org.apache.activemq.artemis.core.server.impl.ActiveMQServerImpl$2 at 41f992ab-83559664)) AMQ221031: backup announced
{code}

Reading server logs to see whether backup is in sync is not convinient and user friendly way. Could we add this information to model so it can be detected through CLI command?

New attribute with name {{synchronized-with-live}} should be added to {{/subsystem=messaging-activemq/server=default/ha-policy=replication-slave}}

This information can be gathered by calling: {{SharedNothingBackupActivation.isRemoteBackupUpToDate()}}

Additionally we should provide this attribute also in replicated live server in: {{/subsystem=messaging-activemq/server=default/ha-policy=replication-master}} as Administrator might want to know whether live can be shutdown.
