Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@opentelemetry/otlp-transformer) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

OpenTelemetry Protocol

Note: This package is intended for internal use only.

Note: This is an experimental package under active development. New releases may include breaking changes.

This package provides everything needed to serialize OpenTelemetry SDK traces, metrics and logs into the OpenTelemetry Protocol format.

Quick Start

To get started you will need to install a compatible OpenTelemetry API.

Install Peer Dependencies

npm install @opentelemetry/api

Serialize Traces/Metrics/Logs

This module exports serializers to serialize traces, metrics and logs from the OpenTelemetry SDK into protocol buffers or JSON which can be sent over HTTP or gRPC (protobuf-only) to the OpenTelemetry collector or a compatible receiver.

import {
  JsonLogsSerializer,
  JsonMetricsSerializer,

} from '@opentelemetry/otlp-transformer';

// serialize to JSON export requests
const serializedJsonLogs: Uint8Array = JsonLogsSerializer.serializeRequest(readableLogRecords);

// deserialize JSON export responses

const deserializedProtobufMetricsResponse: IExportMetricsServiceResponse = ProtobufMetricsSerializer.deserializeResponse(protobufMetricsResponse);
const deserializedProtobufTraceResponse: IExportTraceServiceResponse = ProtobufTraceSerializer.deserializeResponse(protobufTraceResponse);
