long	getFailedRequestCount()	Returns the number of requests that were tried at this node but did not result in a successful response.
int	getMaxActiveRequestCount()	Returns the number of requests that were concurrently active for this node at this KVS client.
java.lang.String	getNodeName()	Returns the internal name associated with the node.
long	getRequestCount()	Returns the total number of requests processed by the node.
java.lang.String	getZoneName()	Returns the zone that hosts the node.
boolean	isActive()	Returns true is the node is currently active, that is, it's reachable and can service requests.

Method Detail

getNodeName

java.lang.String getNodeName()

Returns the internal name associated with the node. It's unique across the KVStore.

getDataCenterName

@Deprecated
java.lang.String getDataCenterName()

Deprecated.

replaced by getZoneName()

Returns the zone that hosts the node.

getZoneName

java.lang.String getZoneName()

Returns the zone that hosts the node.

isActive

boolean isActive()

Returns true is the node is currently active, that is, it's reachable and can service requests.

isMaster

boolean isMaster()

Returns true if the node is currently a master.

getMaxActiveRequestCount

int getMaxActiveRequestCount()

Returns the number of requests that were concurrently active for this node at this KVS client.

getRequestCount

long getRequestCount()

Returns the total number of requests processed by the node.

getFailedRequestCount

long getFailedRequestCount()

Returns the number of requests that were tried at this node but did not result in a successful response.

getAvLatencyMs

int getAvLatencyMs()

Returns the trailing average latency (in ms) over all requests made to this node.

Note that since this is a trailing average it's not cleared when the statistics are cleared via the KVStore.getStats(boolean) method.
