getNumericAttributes in class TurbineData

Returns:

HashMap

getStringAttributes

public java.util.HashMap<java.lang.String,java.lang.String> getStringAttributes()

Specified by:

getStringAttributes in class TurbineData

Returns:

HashMap

getNestedMapAttributes

public java.util.HashMap<java.lang.String,java.util.Map<java.lang.String,? extends java.lang.Number>> getNestedMapAttributes()

Specified by:

getNestedMapAttributes in class TurbineData

Returns:

getReportingHostsCount

public int getReportingHostsCount()

How many hosts have reported to this aggregate data.

Returns:

int: num hosts reporting data

performPostProcessing

public void performPostProcessing()

Called after data is aggregated from a given InstanceMonitor

getReportingDataDebug

public java.lang.String getReportingDataDebug()

addStatsDataFromSingleServer

public void addStatsDataFromSingleServer(DataFromSingleInstance data)

Update the cluster data with the data from this single host.

If this host already added data in the past it will first remove that data (subtract) and then add the newly updated data.

Parameters:

data -

removeDataForHost

public void removeDataForHost(Instance host)

This is called when a host connection gets disconnected and we remove the data from that source.

Parameters:

host -

putIfAbsent

public java.util.concurrent.atomic.AtomicLong putIfAbsent(java.lang.String key,
                                                 java.lang.Long value)
