Class SinglePointMetric

java.lang.Object

io.confluent.telemetry.metrics.SinglePointMetric

All Implemented Interfaces:

Keyed

public class SinglePointMetric
extends Object
implements Keyed

An OpenTelemetry (unbuilt) Metric and its associated MetricKey.

The Metric only has a single data point.

Method Details

key

public MetricKey key()

Specified by:

key in interface Keyed

metric

public io.opentelemetry.proto.metrics.v1.Metric.Builder metric()

create

public static SinglePointMetric create(MetricKey metricKey,
 io.opentelemetry.proto.metrics.v1.Metric.Builder metric)

asAttributes

public static Iterable<io.opentelemetry.proto.common.v1.KeyValue> asAttributes(Map<String,String> labels)

gauge

public static SinglePointMetric gauge(MetricKey metricKey,
 Number value,
 Instant timestamp)

creates a metric data point for arbitrary Number values. Since OpenTelemetry only supports double and long primitive types, the following mapping applies

Long / Integer -> long All other Number types -> double

For fine-grained control, use point(Instant, long) and point(Instant, double)

Parameters:

metricKey -

value -

timestamp -

Returns:

gauge

public static SinglePointMetric gauge(MetricKey metricKey,
 long value,
 Instant timestamp)

public static SinglePointMetric gauge(MetricKey metricKey,
 double value,
 Instant timestamp)
