This element resource has the
following properties:
- averageRequestLatency
- A number that identifies the average time, in milliseconds, that the ZooKeeper node spent receiving and processing requests.
- clientPort
- A number that identifies the port number that the ZooKeeper node uses.
- connectionCount
- A number that identifies the number of clients that are connected to the ZooKeeper node.
- domain
- A string that identifies the URI that you can use to access information about the domain.
- ensemble
- A string that identifies the URI that you can use to access information about the ZooKeeper ensemble that contains the node.
- host
- A string that provides the host identifier for the ZooKeeper node.
- lastZooKeeperTransactionId
- A string that provides an identifier for the most recent transaction on the ZooKeeper node.
- maximumRequestLatency
- A number that identifies the maximum time, in milliseconds, that the ZooKeeper node spent receiving and processing requests.
- minimumRequestLatency
- A number that identifies the minimum time, in milliseconds, that the ZooKeeper node spent receiving and processing requests.
- mode
- A string that identifies the mode of the ZooKeeper node. Some possible values for this property include leader, follower, observer, stand-alone, and unknown.
- name

- outstandingRequestsCount
- A number that identifies the number of requests that were received but not yet processed.
- packetsReceivedCount
- A number that identifies the number of packets that were received by the ZooKeeper node.
- packetsSentCount
- A number that identifies the number of packets that were sent by the ZooKeeper node.
- resourceType
- A string that identifies the REST resource type, which in this case is zooKeeperNode.
- restid
- A string that represents the identifier that is used to uniquely identify the ZooKeeper node within a URI. The value of this property is the same as the value of the name property.
- self
- A string that identifies the URI for this resource.
- status
- A string that identifies the status of the ZooKeeper node. Some possible values for this property include down, latent, notServing, serving, and unknown.
- version
- A string that identifies the version of ZooKeeper on the server.
- znodeCount
- A number that identifies the number of data nodes that are contained in the hierarchy for the ZooKeeper node.
