New releases may include breaking changes.** This module provides a logs-exporter for OTLP (http/json) using protocol version `v1.7.0`. ## Installation ```bash npm install --save @opentelemetry/exporter-logs-otlp-http ``` ## Shared HTTP exporter options This exporter uses the shared HTTP options documented in [`@opentelemetry/otlp-exporter-base`][otlp-exporter-base-config]. That includes `url`, `headers`, `timeoutMillis`, `concurrencyLimit`, and Node.js options such as `compression`, `keepAlive`, `httpAgentOptions`, and `userAgent`. ## Further Documentation To see documentation and sample code for the traces exporter, as well as instructions for using TLS, visit the [Collector Trace Exporter for web and node][trace-exporter-url]. To see documentation and sample code for the metric exporter, see the [exporter-metrics-otlp-grpc package][metrics-exporter-url] ## Logs in Web The OTLPLogExporter in Web expects the endpoint to end in `/v1/logs`. ```js import { SeverityNumber } from '@opentelemetry/api-logs'; import { LoggerProvider, BatchLogRecordProcessor, } from '@opentelemetry/sdk-logs'; import { OTLPLogExporter } from '@opentelemetry/exporter-logs-otlp-http'; // exporter options. see all options in OTLPExporterConfigBase const collectorOptions = { url: '', // url is optional and can be omitted - default is http://localhost:4318/v1/logs headers: {}, // an optional object containing custom headers to be sent with each request concurrencyLimit: 1, // an optional limit on pending requests }; const logExporter = new OTLPLogExporter(collectorOptions); const loggerProvider = new LoggerProvider({ processors: [new BatchLogRecordProcessor({ exporter: logExporter })] }); const logger = loggerProvider.getLogger('default', '1.0.0'); // Emit a log logger.emit({ severityNumber: SeverityNumber.INFO, severityText: 'info', body: 'this is a log body', attributes: { 'log.type': 'custom' }, }); ``` ## Logs in Node ```js import { LoggerProvider, BatchLogRecordProcessor, } from '@opentelemetry/sdk-logs'; import { OTLPLogExporter } from '@opentelemetry/exporter-logs-otlp-http'; // exporter options. see all options in OTLPExporterNodeConfigBase const collectorOptions = { url: '', // url is optional and can be omitted - default is http://localhost:4318/v1/logs concurrencyLimit: 1, // an optional limit on pending requests }; const logExporter = new OTLPLogExporter(collectorOptions); const loggerProvider = new LoggerProvider({ processors: [new BatchLogRecordProcessor({ exporter: logExporter })] }); const logger = loggerProvider.getLogger('default', '1.0.0'); // Emit a log logger.emit({ severityNumber: SeverityNumber.INFO, severityText: 'info', body: 'this is a log body', attributes: { 'log.type': 'custom' }, }); ``` ## Environment Variable Configuration In addition to settings passed to the constructor, the exporter also supports configuration via environment variables: | Environment variable | Description | | -------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | OTEL_EXPORTER_OTLP_ENDPOINT | The endpoint to send logs to. This will also be used for the traces exporter if `OTEL_EXPORTER_OTLP_TRACES_ENDPOINT` is not configured. By default `http://localhost:4318` will be used. `/v1/logs` will be automatically appended to configured values. | | OTEL_EXPORTER_OTLP_LOGS_ENDPOINT | The endpoint to send logs to. By default `http://localhost:4318/v1/logs` will be used. `v1/logs` will not be appended automatically and has to be added explicitly. | | OTEL_EXPORTER_OTLP_LOGS_TIMEOUT | The maximum waiting time, in milliseconds, allowed to send each OTLP log batch. Default is 10000. | | OTEL_EXPORTER_OTLP_TIMEOUT | The maximum waiting time, in milliseconds, allowed to send each OTLP trace/metric/log batch. Default is 10000. | > Settings configured programmatically take precedence over environment variables. Per-signal environment variables take precedence over non-per-signal environment variables. ## 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.
