ip	The IP address of the node
status	-One of online, offline, syncing, shutting -An online status indicates that the node is active, connected to the cluster and fully working. -An offline status indicates that the node is powered down or disconnected form the cluster, but definitely not reachable for any operations. -A syncing status indicates that the nodes is performing a first time connect or reconnection to the cluster and data sync is in progress.
