# Logging

# Introduction

To efficiently operate a node in the Swipechain network or a BridgeChain, logging malfunctions and obtaining insights when errors occur is invaluable. As a Delegate, you also wish to be informed when critical errors occur, and monitor the day-to-day activity of the Delegate Node.

The default logger we provide is winston which allows you to use multiple types of transport with minimal configuration needed.

# A Look Under the Hood

Let's take a closer look at how the logger is bootstrapped and how easy it is to extend it.

const logManager = manager.get("log-manager");
await logManager.makeDriver(new WinstonDriver(options));

return logManager.driver();

The first thing we do is to grab an instance of the LogManager that is available through the container that provides us with all instances of other plugins.

Next, we create an instance of our WinstonDriver which is the concrete implementation of a LoggerInterface provided by @swipechain/core-logger which uses winston.

Imagine how you could implement a TelegramDriver that sends all error messages to your telegram group but logs others into a file.
