New releases may include breaking changes.** This module provides base components for OTLP Exporters, both Web and Node.js. ## Installation ```bash npm install --save @opentelemetry/otlp-exporter-base ``` ## HTTP exporter configuration HTTP JSON and HTTP/protobuf exporters for traces, metrics, and logs share these configuration options. Node.js exporters accept `OTLPExporterNodeConfigBase`, which also includes the options from `OTLPExporterConfigBase`. Configuration precedence is: programmatic options, then per-signal environment variables, then general environment variables, then built-in defaults. | Option | Type | Default | Description | | ------------------ | ------------------------------------------------------------- | --------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------- | | `url` | `string` | `undefined` (default resolved per precedence above) | Collector endpoint URL. | | `headers` | `Record \| HeadersFactory` | `undefined` | Custom HTTP headers. A factory function may be async and must not throw. Exporters still apply required transport headers. | | `concurrencyLimit` | `number` | `30` | Maximum number of in-flight export requests. | | `timeoutMillis` | `number` | `10000` | Maximum time, in milliseconds, to wait for each batch export. | | `compression` | `CompressionAlgorithm.NONE \| CompressionAlgorithm.GZIP` | `CompressionAlgorithm.NONE` | Compression for outgoing OTLP HTTP requests in Node.js. | | `keepAlive` | `boolean` | `true` | Sets `keepAlive` on the Node.js HTTP or HTTPS agent created by the exporter. A `keepAlive` value in `httpAgentOptions` takes precedence. | | `httpAgentOptions` | `http.AgentOptions \| https.AgentOptions \| HttpAgentFactory` | Agent options with `keepAlive: true` | Custom Node.js HTTP or HTTPS agent options, or a factory function that receives the request protocol and returns an agent. | | `userAgent` | `string` | The exporter's default user agent | Prefix to add to the exporter's default `User-Agent` header in Node.js. | | Option | General environment variable | Signal-specific environment variables | | ----------------------- | --------------------------------------- | ------------------------------------------------------------------------------------------------------------------------ | | `url` | `OTEL_EXPORTER_OTLP_ENDPOINT` | `OTEL_EXPORTER_OTLP_TRACES_ENDPOINT`, `OTEL_EXPORTER_OTLP_METRICS_ENDPOINT`, `OTEL_EXPORTER_OTLP_LOGS_ENDPOINT` | | `headers` | `OTEL_EXPORTER_OTLP_HEADERS` | `OTEL_EXPORTER_OTLP_TRACES_HEADERS`, `OTEL_EXPORTER_OTLP_METRICS_HEADERS`, `OTEL_EXPORTER_OTLP_LOGS_HEADERS` | | `timeoutMillis` | `OTEL_EXPORTER_OTLP_TIMEOUT` | `OTEL_EXPORTER_OTLP_TRACES_TIMEOUT`, `OTEL_EXPORTER_OTLP_METRICS_TIMEOUT`, `OTEL_EXPORTER_OTLP_LOGS_TIMEOUT` | | `compression` | `OTEL_EXPORTER_OTLP_COMPRESSION` | `OTEL_EXPORTER_OTLP_TRACES_COMPRESSION`, `OTEL_EXPORTER_OTLP_METRICS_COMPRESSION`, `OTEL_EXPORTER_OTLP_LOGS_COMPRESSION` | | `concurrencyLimit` | Not supported | Not supported | | `keepAlive` | Not supported | Not supported | | `httpAgentOptions.ca` | `OTEL_EXPORTER_OTLP_CERTIFICATE` | `OTEL_EXPORTER_OTLP_{TRACES,METRICS,LOGS}_CERTIFICATE` | | `httpAgentOptions.cert` | `OTEL_EXPORTER_OTLP_CLIENT_CERTIFICATE` | `OTEL_EXPORTER_OTLP_{TRACES,METRICS,LOGS}_CLIENT_CERTIFICATE` | | `httpAgentOptions.key` | `OTEL_EXPORTER_OTLP_CLIENT_KEY` | `OTEL_EXPORTER_OTLP_{TRACES,METRICS,LOGS}_CLIENT_KEY` | | `userAgent` | Not supported | Not supported | ## GRPC For GRPC please check [npm-url-grpc] ## Useful links - For more information on OpenTelemetry, visit: - For more about OpenTelemetry JavaScript: - For help or feedback on this project, join us in [GitHub Discussions][discussions-url] ## License Apache 2.0 - See [LICENSE][license-url] for more information.
