Module otlp 

The part of the OpenTelemetry metrics protocol (OTLP) that a KIP-714 client pushes.

The metrics field of a PushTelemetry request holds a serialized opentelemetry.proto.metrics.v1.MetricsData. Kafka’s client builds it with the generated protobuf classes. A client only needs number gauges and number sums with string attributes, so this module encodes and decodes that subset of the protobuf wire format by hand. Fields outside the subset are skipped on decode.

Structs

KeyValue

opentelemetry.proto.common.v1.KeyValue with a string value, the only kind of attribute that Kafka writes.

Metric

opentelemetry.proto.metrics.v1.Metric with a gauge or a sum.

MetricsData

opentelemetry.proto.metrics.v1.MetricsData.

NumberDataPoint

opentelemetry.proto.metrics.v1.NumberDataPoint.

OtlpDecodeError

A payload that is not a well-formed MetricsData.

Resource

opentelemetry.proto.resource.v1.Resource.

ResourceMetrics

opentelemetry.proto.metrics.v1.ResourceMetrics.

ScopeMetrics

opentelemetry.proto.metrics.v1.ScopeMetrics, without the instrumentation scope, which Kafka does not set.

Enums

AggregationTemporality

opentelemetry.proto.metrics.v1.AggregationTemporality.

MetricData

The data of a Metric.

NumberValue

The value oneof of a NumberDataPoint.
