MetricsStochasticBalancer

public MetricsStochasticBalancer()

方法详细资料

initSource

protected void initSource()

This function overrides the initSource in the MetricsBalancer, use MetricsStochasticBalancerSource instead of the MetricsBalancerSource.

覆盖:

initSource 在类中 MetricsBalancer

balanceCluster

public void balanceCluster(long time)

覆盖:

balanceCluster 在类中 MetricsBalancer

incrMiscInvocations

public void incrMiscInvocations()

覆盖:

incrMiscInvocations 在类中 MetricsBalancer

balancerStatus

public void balancerStatus(boolean status)

Updates the balancer status tag reported to JMX

覆盖:

balancerStatus 在类中 MetricsBalancer

updateMetricsSize

public void updateMetricsSize(int size)

Updates the number of metrics reported to JMX

updateStochasticCost

public void updateStochasticCost(String tableName,
                                 String costFunctionName,
                                 String costFunctionDesc,
                                 Double value)

Reports stochastic load balancer costs to JMX
