Master Microservices with Spring Boot and Spring Cloud - Step 36 – Implementing Spring Cloud Sleuth

The video tutorial explains how to implement Spring Cloud Sleuth in a microservices architecture to trace requests across multiple components. It covers adding Sleuth dependencies to the API Gateway, currency conversion, and exchange services, and setting up logging to track requests. The tutorial also introduces Zipkin for centralized logging and offers tips for managing application load.

What is the primary function of Spring Cloud Sleuth?

• To enhance security across microservices

• To add a unique ID to requests for tracing

• To improve application performance

• To manage service configurations

Which file needs to be modified to add Spring Cloud Sleuth to a component?

• pom.xml

• build.gradle

• settings.gradle

• application.properties

What is the purpose of creating an AlwaysSampler in Spring Cloud Sleuth?

• To filter out unnecessary logs

• To ensure all requests are traced

• To enhance security

• To improve application speed

In what order should the applications be launched for proper functioning?

• Currency Conversion Service, API Gateway, Naming Server, Currency Exchange Service

• API Gateway, Naming Server, Currency Exchange Service, Currency Conversion Service

• Naming Server, Currency Exchange Service, Currency Conversion Service, API Gateway

• Currency Exchange Service, Naming Server, API Gateway, Currency Conversion Service

What is the main benefit of adding logging in the exchange and conversion services?

• To improve application speed

• To trace requests with unique IDs

• To enhance security

• To reduce server load

What problem does Zipkin solve in a distributed system?

• It reduces application load

• It enhances security across services

• It manages service configurations

• It centralizes logs for easier tracing

What can be done to reduce the load when running multiple applications?

• Increase server memory

• Remove Spring Boot Actuator and Dev Tools dependencies

• Use a faster internet connection

• Upgrade to a newer version of Java
