In order to set the service name, use the `service.name` resource attribute as prescribed in the [OpenTelemetry Resource Semantic Conventions][semconv-resource-service-name]. ## Traces in Node - PROTO over http ```js const { BasicTracerProvider, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base'); const { OTLPTraceExporter } = require('@opentelemetry/exporter-otlp-proto'); const collectorOptions = { url: '', // url is optional and can be omitted - default is http://localhost:55681/v1/traces headers: { foo: 'bar' }, //an optional object containing custom headers to be sent with each request will only work with http }; const provider = new BasicTracerProvider(); const exporter = new OTLPTraceExporter(collectorOptions); provider.addSpanProcessor(new SimpleSpanProcessor(exporter)); provider.register(); ``` ## Metrics in Node - PROTO over http ```js const { MeterProvider } = require('@opentelemetry/sdk-metrics-base'); const { OTLPMetricExporter } = require('@opentelemetry/exporter-otlp-proto'); const collectorOptions = { url: '', // url is optional and can be omitted - default is http://localhost:55681/v1/metrics }; const exporter = new OTLPMetricExporter(collectorOptions); // Register the exporter const meter = new MeterProvider({ exporter, interval: 60000, }).getMeter('example-meter'); // Now, start recording data const counter = meter.createCounter('metric_name'); counter.add(10, { 'key': 'value' }); ``` ## Running opentelemetry-collector locally to see the traces 1. Go to examples/otlp-exporter-node 2. run `npm run docker:start` 3. Open page at `http://localhost:9411/zipkin/` to observe the traces ## 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.
