Class AggregateClusterMonitor

java.lang.Object

com.netflix.turbine.monitor.TurbineDataMonitor<K>

com.netflix.turbine.monitor.cluster.ClusterMonitor<AggDataFromCluster>

com.netflix.turbine.monitor.cluster.AggregateClusterMonitor

public class AggregateClusterMonitor
extends ClusterMonitor<AggDataFromCluster>

An implementation of the ClusterMonitor class that aggregates data from multiple InstanceMonitor objects for all hosts in the same cluster.

It provides it's own ObservationCriteria which decides what hosts to monitor. The criteria looks for all the hosts matching the same cluster name.

Method Detail

findOrRegisterAggregateMonitor

public static TurbineDataMonitor<AggDataFromCluster> findOrRegisterAggregateMonitor(java.lang.String clusterName)

startMonitor

public void startMonitor()
                  throws java.lang.Exception

Description copied from class: ClusterMonitor

Start the monitor and register with the InstanceObservable to get updates on host status

Overrides:

startMonitor in class ClusterMonitor<AggDataFromCluster>

Throws:

java.lang.Exception

stopMonitor

public void stopMonitor()

Description copied from class: ClusterMonitor

Stop the monitor, shut down resources that were created and notify listeners downstream about the event.

Overrides:

stopMonitor in class ClusterMonitor<AggDataFromCluster>

getEventHandler

public TurbineDataHandler<DataFromSingleInstance> getEventHandler()

Description copied from class: ClusterMonitor

To be implemented by extending cluster monitors such as the aggregator.

Specified by:

getEventHandler in class ClusterMonitor<AggDataFromCluster>

Returns:

TurbineDataHandler<DataFromSingleInstance>

getObservationCriteria

public ObservationCriteria getObservationCriteria()

Specified by:

getObservationCriteria in class ClusterMonitor<AggDataFromCluster>

Returns:

ObservationCriteria

getMetaInformation

protected MetaInformation<AggDataFromCluster> getMetaInformation()

Description copied from class: ClusterMonitor

Track meta info for this cluster. This feature is optional. Do not override if you don't want meta info from your cluster monitor. One can set the config property 'turbine.MetaInfoUpdator.enabled' to value 'false' to turn off the updator as well.

Overrides:

getMetaInformation in class ClusterMonitor<AggDataFromCluster>

Returns:

getReportingDataDebug

removeKey

public void removeKey(java.lang.String type,
             java.lang.String name)

Useful for administrative operations. Evicts the data pointed to by the key from the map

Parameters:

type -

name -

removeAllKeys

public void removeAllKeys()

Useful for administrative operations. Evicts the data pointed to by the key from the map
