Method Details

createDoubleHistogram

public io.opentelemetry.api.metrics.DoubleHistogram createDoubleHistogram(MetricEntity metricEntity)

createLongCounter

public io.opentelemetry.api.metrics.LongCounter createLongCounter(MetricEntity metricEntity)

createLongGuage

public io.opentelemetry.api.metrics.LongGauge createLongGuage(MetricEntity metricEntity)

createAsyncLongGauge

public io.opentelemetry.api.metrics.ObservableLongGauge createAsyncLongGauge(MetricEntity metricEntity,
 @Nonnull
 LongSupplier asyncCallback,
 @Nonnull
 io.opentelemetry.api.common.Attributes attributes)

Asynchronous gauge that will call the callback during metrics collection. This is useful for metrics that are not updated frequently or require expensive computation. For now, the attributes are passed in as a parameter while creating the gauge, ie, only MetricEntityStateBase is supported for now.

createInstrument

public Object createInstrument(MetricEntity metricEntity,
 LongSupplier asyncCallback,
 io.opentelemetry.api.common.Attributes attributes)

createInstrument

public Object createInstrument(MetricEntity metricEntity)

getDimensionName

public String getDimensionName(VeniceMetricsDimensions dimension)

createAttributes

public io.opentelemetry.api.common.Attributes createAttributes(MetricEntity metricEntity,
 Map<VeniceMetricsDimensions,String> baseDimensionsMap,
 VeniceDimensionInterface... additionalDimensionEnums)

createAttributes

public io.opentelemetry.api.common.Attributes createAttributes(MetricEntity metricEntity,
 Map<VeniceMetricsDimensions,String> baseDimensionsMap,
 Map<VeniceMetricsDimensions,String> additionalDimensionsMap)

close

public void close()

recordFailureMetric

public void recordFailureMetric(MetricEntity metricEntity,
 Exception e)

recordFailureMetric

public void recordFailureMetric(MetricEntity metricEntity,
 String error)

emitOpenTelemetryMetrics

public boolean emitOpenTelemetryMetrics()

getMetricsConfig
