Method Detail

getMemberId

public static String getMemberId(com.hazelcast.core.Member member)

While we could just use the Member UUID here, this would change on every restart. By using the socketAddress as the basis for the node identifier, it will mostly remain the same across restarts, making diagnosis of node affinity problems easier. Also, InetSocketAddress has a bad hashCode implementation, so we bypass it.

getMemberNodeIdentifier

public static com.atlassian.cluster.monitoring.spi.model.NodeIdentifier getMemberNodeIdentifier(com.hazelcast.core.Member member)

getMemberSelector

public static com.hazelcast.core.MemberSelector getMemberSelector(com.atlassian.cluster.monitoring.spi.model.NodeIdentifier nodeIdentifier)

extractNodeId

public static Function<com.hazelcast.core.Member,com.atlassian.cluster.monitoring.spi.model.NodeIdentifier> extractNodeId()

getConfiguredMemberName

public static Optional<String> getConfiguredMemberName(com.hazelcast.core.Member member)

extractNodeInfo

public static Function<com.hazelcast.core.Member,com.atlassian.cluster.monitoring.spi.model.NodeInformation> extractNodeInfo()
