All Implemented Interfaces:

ExportableMetric, Keyed

public class ClientExportableMetric
extends ContextExportableMetric

The ClientExportableMetric class extends ContextExportableMetric to process client metrics telemetry data. It is responsible for organizing resource-level and scope-level attributes in a Metric/MetricsData payload and ensuring proper formatting for export.

Method Details

metric

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

Returns the metric with resource attributes, brokerLabels and requestLabels added to the metric data point. The HttpExporter uses getMetric() to get the metric data point for export. A copy of the metric is created, and all relevant attributes from resource attributes, broker labels, and request labels are added to the metric's data point before export.

The method first retrieves the base metric from the parent class using super.getMetric() to get the original metric structure. This original metric is then enhanced with client-specific attributes by adding them to the metric's data point, preserving the metric's core data while adding the necessary context for client telemetry.
