Map<MetricEntity, MetricSummaryValueEntity> com.griddynamics.jagger.engine.e1.services.DefaultDataService.getMetricSummary

(

Collection< MetricEntity >

metrics)

Return summary values for selected metrics.

Parameters

metrics

- metric entities

Returns

map of <metric entity, summary>

Preferable way to get data. Data will be fetched from database in batch in single request =>
it is faster to get batch of metrics than fetch every metric in for loop
