Overview

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:

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

Reading server logs to see whether backup is in sync is not convenient and user friendly way. By adding a new attribute on the live and backup nodes the user should be able to know when this synchronization is finished.

Requirements

Add a boolean synchronized-with-backup runtime-only attribute to the /subsystem=messaging-activemq//server=*/ha-policy=replication-master.
Add a boolean synchronized-with-live runtime-only attribute to the /subsystem=messaging-activemq//server=*/ha-policy=replication-slave.

Nice-to-Have Requirements

Non-Requirements

Implementation Plan

Expose org.apache.activemq.artemis.api.core.management.ActiveMQServerControl#isReplicaSync as it represents the synchronization status of the backup with the live node on each node.

Test Plan

Changes in Wildfly management model will be covered in WF testsuite.
