Interface NodeMetrics

All Superinterfaces:

Serializable

public interface NodeMetrics
extends Serializable

The metrics associated with a node in the KVS.

Method Summary

int	getAvLatencyMs() Returns the trailing average latency (in ms) over all requests made to this node.
String	getDataCenterName() Returns the data center that hosts the node.
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.
String	getNodeName() Returns the internal name associated with the node.
long	getRequestCount() Returns the total number of requests processed by the node.
boolean	isActive() Returns true is the node is currently active, that is, it's reachable and can service requests.
boolean	isMaster() Returns true if the node is currently a master.

Method Detail

getNodeName

String getNodeName()

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

getDataCenterName

String getDataCenterName()

Returns the data center 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.
