Returns the set of current cluster members.

Returns:

set of cluster members

getConsensusNodes

Set<Node> getConsensusNodes()

Returns the set of consensus nodes.

Returns:

the set of consensus nodes

getNode

ControllerNode getNode(NodeId nodeId)

Returns the specified controller node.

Returns:

controller version

getLastUpdatedInstant

default Instant getLastUpdatedInstant(NodeId nodeId)

Returns the system time when the availability state was last updated.

Parameters:

nodeId - controller node identifier

Returns:

system time when the availability state was last updated.

localStatus

default String localStatus(NodeId nodeId)

Returns a human readable form of the system time when the availability state was last updated.

Parameters:

nodeId - controller node identifier
