Building Microservices API in Go - Structured Logging

The video introduces structured logging, emphasizing its importance in application infrastructure. It highlights the challenges of unstructured logs and the benefits of using structured formats like JSON. The tutorial demonstrates implementing structured logging in Go using Uber Zap, customizing configurations, and exploring advanced features. The video concludes with a recap and a brief introduction to SQL X.

Why is logging considered a cross-cutting concern in application infrastructure?

• It is not essential for application infrastructure.

• It spans across all layers of an application.

• It is only needed during the development phase.

• It only affects the user interface layer.

What is a major problem with unstructured log data?

• It is always stored in JSON format.

• It cannot be collected by logging aggregators.

• It requires multiple parsers for different formats.

• It is too easy to read.

Which Go library is highlighted for its performance in structured logging?

• Uber ZAP

• Elasticsearch

• Paper Trail

• Logly

What is the first step in setting up the Uber ZAP logger?

• Create a new database.

• Write custom parsers for logs.

• Install the library and add it to module dependencies.

• Use the standard library for logging.

What is the purpose of creating helper functions for the ZAP logger?

• To increase dependency on the logging library.

• To expose logging functionality through custom functions.

• To make the logger public.

• To avoid using any logging library.

How can you ensure the correct origin of log messages in ZAP?

• By using a different logging library.

• By ignoring the caller information.

• By setting the caller skip value.

• By using the standard logger.

What format is used to change the timestamp in ZAP logs?

• Local time

• Unix time

• ISO 8601

• Epoch time

What is a benefit of using structured logging for developers?

• It complicates the log data.

• It requires more storage space.

• It makes debugging easier.

• It is only useful for end-users.

What should you do if you want to change the logging library in the future?

• Rewrite the entire application.

• Change the helper functions in the logger file.

• Remove all logging from the application.

• Use multiple logging libraries simultaneously.

What is the next topic introduced after structured logging?

• SQL X

• User interface design

• Security

• Error handling
