Justin Bertram commented on ARTEMIS-517:
----------------------------------------
Are you wanting to be able to execute this on the backup server or on the live
server or both?
{{org.apache.activemq.artemis.core.server.impl.SharedNothingBackupActivation#isRemoteBackupUpToDate}}
already exists for the backup. Of course, the traditional management
mechanisms won't be available until the backup actually becomes live.
For the live server,
{{org.apache.activemq.artemis.core.server.impl.Activation#getReplicationManager}}
exists already which (if not null) can be used to invoke
{{org.apache.activemq.artemis.core.replication.ReplicationManager#isSynchronizing()}}.
If that returns {{false}} then you know the live and backup have synced up.
> Provide public API method to check whether backup is synchronized with live
> server

> Key: ARTEMIS-517
> URL: https://issues.apache.org/jira/browse/ARTEMIS-517
> Project: ActiveMQ Artemis
> Issue Type: New Feature
> Components: Broker
> Affects Versions: 1.2.0
> Reporter: Miroslav Novak
> Assignee: Justin Bertram
>
> 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@41f992ab-83559664))
> AMQ221031: backup announced
> {code}
> Reading server logs to see whether backup is in sync is not convenient and
> user friendly way.
> We should provide public API to check state of synchronization. It should be
> added to {{Activation}} interface.
> This method should be implemented for {{SharedNothingBackupActivation}} and
> also {{SharedNothingLiveActivation}}.
