Method Details

getResource

io.opentelemetry.sdk.resources.Resource getResource()

Returns the metric Resource.

The Resource is configured via SdkMeterProviderBuilder.setResource(Resource).

getInstrumentationScopeInfo

io.opentelemetry.sdk.common.InstrumentationScopeInfo getInstrumentationScopeInfo()

Returns the metric InstrumentationScopeInfo.

The InstrumentationScopeInfo is determined from the options used when MeterBuilder.build()ing the Meter.

getName

String getName()

Returns the metric name.

The metric name is typically the instrument name, but may be optionally overridden by a View.

getDescription

String getDescription()

Returns the metric description.

The metric name is typically the instrument description, but may be optionally overridden by a View.

getUnit

String getUnit()

Returns the metric unit.

getType

MetricDataType getType()

Returns the type of this metric.

getData

Data<?> getData()

Returns the unconstrained metric data.

Most will instead prefer to access the constrained metric data after first checking the getType():

 //  if (metricData.getType() == MetricDataType.LONG_SUM) {
 //    SumData<LongPointData> sumData = metricData.getLongSumData();
 //    ... // Process long sum data
 //  }

isEmpty

default boolean isEmpty()

Returns true if there are no points associated with this metric.

getDoubleGaugeData

default GaugeData<DoublePointData> getDoubleGaugeData()

Returns the double GaugeData if type is MetricDataType.DOUBLE_GAUGE, otherwise a default empty data.

getLongGaugeData

default GaugeData<LongPointData> getLongGaugeData()

Returns the long GaugeData if type is MetricDataType.LONG_GAUGE, otherwise a default empty data.

getDoubleSumData

default SumData<DoublePointData> getDoubleSumData()

Returns the double SumData if type is MetricDataType.DOUBLE_SUM, otherwise a default empty data.

getLongSumData

default SumData<LongPointData> getLongSumData()

Returns the long SumData if type is MetricDataType.LONG_SUM, otherwise a default empty data.

getSummaryData

default SummaryData getSummaryData()

Returns the SummaryData if type is MetricDataType.SUMMARY, otherwise a default empty data.

getHistogramData

default HistogramData getHistogramData()

Returns the HistogramData if type is MetricDataType.HISTOGRAM, otherwise a default empty data.

getExponentialHistogramData

default ExponentialHistogramData getExponentialHistogramData()

Returns the ExponentialHistogramData if type is MetricDataType.EXPONENTIAL_HISTOGRAM, otherwise a default empty data.
