Sobre este producto
- Book DescriptionDebugging is probably the most important skill that most people are never taught.Being able to debug locally and in production is a critical skill for any Go engineer, but it is rarely taught explicitly. It has taken me many years of working with Go in production to get comfortable debugging, and I want to accelerate your learning by teaching you everything I wish I had known when I started out. In this book you'll learn:How to get better at spotting issues by eye.Logging patterns and how to build an enterprise logging strategy.What are metrics, how to create them and how to build great dashboards.What distributed tracing is, and how to set it up in your company.How to use Go's profiling tools to debug performance issues use and squeeze every ounce of performance out of your application.Who's this book for? This book is aimed at junior and intermediate Go Developers. A working knowledge of Go is assumed.
