This package provides Amazon Web Services distribution of the OpenTelemetry Node Instrumentation, which allows for auto-instrumentation of NodeJS applications.

/**
 * This exporter will update a span with metric attributes before exporting. It depends on a
 * {@link SpanExporter} being provided on instantiation, which the AwsMetricAttributesSpanExporter will
 * delegate export to. Also, a {@link MetricAttributeGenerator} must be provided, which will provide a
 * means to determine attributes which should be applied to the span. Finally, a {@link Resource} must
 * be provided, which is used to generate metric attributes.
 *
 * <p>This exporter should be coupled with the {@link AwsSpanMetricsProcessor} using the same
 * {@link MetricAttributeGenerator}. This will result in metrics and spans being produced with
 * common attributes.
