[dependabot]

Bumps opentelemetry-exporter-otlp-metrics from 1.4.1-alpha to 1.14.0.

Release notes

Sourced from opentelemetry-exporter-otlp-metrics's releases.

Version v1.14.0

This release targets the OpenTelemetry SDK 1.14.0.

The metrics SDK is stable! New stable artifacts include:

• io.opentelemetry:opentelemetry-sdk-metrics (also now included in io.opentelemetry:opentelemetry-sdk)
• io.opentelemetry:opentelemetry-exporter-otlp-metrics (also now included in io.opentelemetry:opentelemetry-exporter-otlp)
• io.opentelemetry:opentelemetry-exporter-otlp-http-metrics
• Metrics testing components have been moved from io.opentelemetry:opentelemetry-sdk-metrics-testing to the stable io.opentelemetry:opentelemetry-sdk-testing.

While the API of the metrics SDK is now stable, there are a couple of known issues that will be addressed in the next release:

• The start time is incorrect for delta metrics when the first recording for a set of attributes occurs after the first collections (#4400).
• Registering multiple readers results in incorrect metrics (#4436).

SDK

Traces

• Fix bug where non-runtime exception breaks BatchSpanProcessor.
• Fix bug preventing attribute limits from applying to exception events.

Logs

• BREAKING: Drop deprecated methods referencing InstrumentationLibraryInfo from Log SDK.

Metrics

• Instrument name is validated. If invalid, a warning is logged and a noop instrument is returned.
• Default unit is empty instead of 1. If an invalid unit is set, a warning is logged and empty is used.
• Ensure symmetry between type of PointData and their type of exemplars (double or long).
• BREAKING: Rename MetricReader#flush() to MetricReader#forceFlush().
• Introduce AggregationTemporalitySelector interface for selecting aggregation temporality based on instrument. MetricReader and MetricExporter extend AggregationTemporalitySelector.

SDK Extensions

• BREAKING: Remove deprecated option to specify temporality with otel.exporter.otlp.metrics.temporality. Use otel.exporter.otlp.metrics.temporality.preference instead.
• Log warning when AwsXrayPropagator can't identify parent span id.
• Fix jaeger remote sampling bug preventing correct parsing of 0-probability sampling strategies.

Exporter

• Fix prometheus exporter formatting bug when there are no attributes.
• Ensure prometheus metrics with the same name are serialized as a group.
• BREAKING: OtlpHttpMetricExporterBuilder and OtlpGrpcMetricExporterBuilder configure aggregation temporality via #setAggregationTemporalitySelector(AggregationTemporalitySelector).

Testing

• BREAKING: Metrics testing components added to stable io.opentelemetry:opentelemetry-sdk-testing module, including InMemoryMetricReader, InMemoryMetricExporter, and MetricAssertions.assertThat(MetricData) has been moved to OpenTelemetryAssertions.assertThat(MetricData).
• BREAKING: The patterns for metrics assertions have been adjusted to better align with assertj conventions. See #4444 for examples demonstrating the change in assertion patterns.
