public class AggregatingSubtasksMetricsHandler
extends AbstractAggregatingMetricsHandler<AggregatedSubtaskMetricsParameters>

Request handler that returns, aggregated across subtasks, a list of all available metrics or the values for a set of metrics.

Specific subtasks can be selected for aggregation by specifying a comma-separated list of integer ranges. /metrics?get=X,Y&subtasks=0-2,4-5
