What is structured logging and why is it important?

Structured logging is a method of logging where log entries are formatted in a consistent, machine-readable way. This allows for easier searching, filtering, and analysis of logs.

How does structured logging differ from traditional logging?

Traditional logging often uses plain text, making it hard to parse and analyze. Structured logging uses key-value pairs, which can be easily processed by tools.

Can you give me an example of structured logging in Go?

Sure! In Go, you can use libraries like 'logrus' or 'zap' to create structured logs. For example, you can log a user event like this: log.WithFields(log.Fields{'user_id': 123, 'action': 'login'}).Info('User logged in').

What are the benefits of using structured logging?

The benefits include improved log readability, easier debugging, better performance in log analysis, and enhanced ability to correlate logs with events.
