Method Detail

registerCustomResources

public void registerCustomResources(Map<String,Long> customResources,
                                    org.apache.hadoop.metrics2.lib.MetricsRegistry registry)

Register all custom resources metrics as part of initialization.

Parameters:

customResources - Map containing all custom resource types

registry - of the metric type

initAndGetCustomResources

public Map<String,Long> initAndGetCustomResources()

Get a map of all custom resource metric.

Returns:

map of custom resource

registerCustomResources

public void registerCustomResources(Map<String,Long> customResources,
                                    org.apache.hadoop.metrics2.lib.MetricsRegistry registry,
                                    String metricPrefix,
                                    String metricDesc)

As and when this metric object construction happens for any queue, all custom resource metrics value would be initialized with '0' like any other mandatory resources metrics.

Parameters:

customResources - Map containing all custom resource types

registry - of the metric type

metricPrefix - prefix in metric name
