If you don't have node.js installed, please install it and then follow below steps.

Open tracing.js file from that repository. and make changes to the highlighted lines below


const opentelemetry = require("@opentelemetry/sdk-node");
const {
  getNodeAutoInstrumentations,
} = require("@opentelemetry/auto-instrumentations-node");
const { diag, DiagConsoleLogger, DiagLogLevel } = require("@opentelemetry/api");
const {
  OTLPTraceExporter,
} = require("@opentelemetry/exporter-trace-otlp-http");

// For troubleshooting, set the log level to DiagLogLevel.DEBUG
diag.setLogger(new DiagConsoleLogger(), DiagLogLevel.INFO);

const sdk = new opentelemetry.NodeSDK({
  // traceExporter: new opentelemetry.tracing.ConsoleSpanExporter(),
  traceExporter: new opentelemetry.tracing.ConsoleSpanExporter(),
  traceExporter: new OTLPTraceExporter({
    url: "https://api.openobserve.ai/api/default/v1/traces",
    headers: {
      Authorization: "Authorization",
    },
  }),
  instrumentations: [getNodeAutoInstrumentations()],
  serviceName: "nodejs-javascript-service",
});

sdk.start();
