@opentelemetry/winston-transport v0.3.0

OpenTelemetry transport for winston

This module provides a Transport for winston module to send Winston logging to the OpenTelemetry Logging SDK.

Compatible with OpenTelemetry JS API and SDK 1.0+.

Installation

npm install --save @opentelemetry/winston-transport

Usage

This package exports the Winston transport class that is used to send records to the OpenTelemetry Logs SDK. It can be used directly when configuring a Winston logger. If using @opentelemetry/instrumenation-winston package there is no need to instantiate the transport as the instrumentation will take care of that. For example:

const logsAPI = require('@opentelemetry/api-logs');
const {
    LoggerProvider,
    SimpleLogRecordProcessor,
    ConsoleLogRecordExporter,
} = require('@opentelemetry/sdk-logs');
const { OpenTelemetryTransportV3 } = require('@opentelemetry/winston-transport');
const winston = require('winston');


// To start a logger, you first need to initialize the Logger provider.
const loggerProvider = new LoggerProvider();
// Add a processor to export log record
loggerProvider.addLogRecordProcessor(
    new SimpleLogRecordProcessor(new ConsoleLogRecordExporter())
);
logsAPI.logs.setGlobalLoggerProvider(loggerProvider);

const logger = winston.createLogger({
  level: 'info',
  transports: [
    new winston.transports.Console(),
    new OpenTelemetryTransportV3()
  ]
});

Supported versions

Winston 3.x
