createHandle
Description copied from interface:Aggregator
Returns a newAggregatorHandle
. This MUST by used by the synchronous to aggregate recorded measurements during the collection cycle.- Specified by:
createHandle
in interfaceAggregator<ExponentialHistogramPointData,
DoubleExemplarData> - Returns:
- a new
AggregatorHandle
.
-
toMetricData
public MetricData toMetricData(Resource resource, InstrumentationScopeInfo instrumentationScopeInfo, MetricDescriptor metricDescriptor, Collection<ExponentialHistogramPointData> points, AggregationTemporality temporality) Description copied from interface:Aggregator
Returns theMetricData
that thisAggregation
will produce.- Specified by:
toMetricData
in interfaceAggregator<ExponentialHistogramPointData,
DoubleExemplarData> - Parameters:
resource
- the resource producing the metric.instrumentationScopeInfo
- the scope that instrumented the metric.metricDescriptor
- the name, description and unit of the metric.points
- list of pointstemporality
- the temporality of the metric.- Returns:
- the
MetricDataType
that thisAggregation
will produce.
