Class PerformanceCriteria.AggClusterPerformanceCriteria

java.lang.Object

com.netflix.turbine.handler.PerformanceCriteria.AggClusterPerformanceCriteria

All Implemented Interfaces:

PerformanceCriteria

Enclosing interface:

PerformanceCriteria

public static class PerformanceCriteria.AggClusterPerformanceCriteria
extends java.lang.Object
implements PerformanceCriteria

Sample criteria that is used by the AggregateClusterMonitor.getEventHandler() to handle data from multiple InstanceMonitor connections.

Note that one can configure the perf size for each cluster that is being run by Turbine using the properties turbine.aggCluster.performance.queueSize.[clusterName] and turbine.aggCluster.performance.numThreads.[clusterName]

Method Detail

isCritical

public boolean isCritical()

Description copied from interface: PerformanceCriteria

Do we care about this handler's performance? Sometimes we use dummy handlers e.g STATIC LISTENER There are 2 main arguments here 1. Queue Size - how many elements should be queued before the next elements start being discarded. This is related to latency of the data 2. How many threads are allowed to pull data simultaneously off the queue and dispatch to the handler in parallel

Specified by:

isCritical in interface PerformanceCriteria

Returns:

boolean

numThreads

public int numThreads()

Description copied from interface: PerformanceCriteria

What is the no of threads that the handler would like to have data sent from.

Specified by:

numThreads in interface PerformanceCriteria

Returns:
