Example 6 with ClusterNodeInfo

use of org.jivesoftware.openfire.cluster.ClusterNodeInfo in project Openfire by igniterealtime.

the class ClusterListener method memberAttributeChanged.

@Override
public void memberAttributeChanged(MemberAttributeEvent event) {
    ClusterNodeInfo priorNodeInfo = clusterNodesInfo.get(event.getMember().getUuid());
    clusterNodesInfo.put(event.getMember().getUuid(), new HazelcastClusterNodeInfo(event.getMember(), priorNodeInfo.getJoinedTime()));
}

Example 7 with ClusterNodeInfo

use of org.jivesoftware.openfire.cluster.ClusterNodeInfo in project Openfire by igniterealtime.

the class ConsistencyChecks method generateReportForRoutingTableComponentRoutes.

/**
 * Verifies that #componentsCache, #localRoutingTable#getComponentRoute and #componentsByClusterNode of
 * {@link org.jivesoftware.openfire.spi.RoutingTableImpl} are in a consistent state.
 * <p>
 * Note that this operation can be costly in terms of resource usage. Use with caution in large / busy systems.
 * <p>
 * The returned multi-map can contain up to four keys: info, fail, pass, data. All entry values are a human readable
 * description of a checked characteristic. When the state is consistent, no 'fail' entries will be returned.
 *
 * @param componentsCache         The cache that is used to share data across cluster nodes
 * @param localComponentRoutes    The data structure that keeps track of what data was added to the cache by the local cluster node.
 * @param componentsByClusterNode The data structure that keeps track of what data was added to the cache by the remote cluster nodes.
 * @return A consistency state report.
