npm install pino @opentelemetry/instrumentation-pino
NodeSDK instrumentations:const { PinoInstrumentation } = require('@opentelemetry/instrumentation-pino');
instrumentations: [
getNodeAutoInstrumentations(),
new PinoInstrumentation(),
],
logger.info({ count: 3 }, 'order listed');
logger.error({ err }, 'payment failed');
npm install winston @opentelemetry/instrumentation-winston
const { WinstonInstrumentation } = require('@opentelemetry/instrumentation-winston');
instrumentations: [
getNodeAutoInstrumentations(),
new WinstonInstrumentation(),

logger.info('order listed', { count: 3 });
logger.error('payment failed', { err });
