Implementation of Monitoring and Logging in Spring Cloud Config Server

Below is the implementation of Monitoring and Logging in Spring Cloud Config Server.

Setup the Config Server

Step 1: Create a spring project using spring initializer and add the below required dependencies.

Dependencies:

• Spring Web
• Spring Dev Tools
• Lombok
• Spring Cloud Config Server
• Spring Boot Actuator

After creating the Spring project, the file structure will be like below.

Step 2: Open the application.properties file and add the configuring the server port and git repository uri configuration, actuator and logging configurations of the application.

spring.application.name=config-server

server.port=8888
spring.cloud.config.server.git.uri=https://github.com/iammahesh123/spring-cloud-config-server.git

# Actuator settings
management.endpoints.web.exposure.include=health,info,metrics

#logging
logging.level.org.springframework.cloud.config.server=DEBUG

logging.file.name=config-server.log

Git repository application.yml code:

some.config.value=Hello from Config Server!

Step 3: Create the Logback.xml and put the below code for the logging configuration of the Spring Boot application.

Go to src > main > resources > Logback.xml and put the below code.

Step 4: Open the main class, add the @EnableConfigServer annotation to activate the Spring cloud config functionality of the application.

Go to src > main >java > org.example.configserver > ConfigServerApplication and put the below code.

Step 5: Run the application

Once the Spring project is completed and successfully runs as a Spring application, it will start at port 8888.

View the Logs: Once run the application that generates the logs of the application, it looks like below information.

Setup the Client-application

Step 1: Create a spring project using spring initializer and add the below required dependencies.

Dependencies:

• Spring Web
• Spring Dev Tools
• Lombok
• Spring Cloud Config Client

After creating the Spring project, the file structure will be like below.

Step 2: Open the application.properties file and add the configuring the server port and import git uri configuration.

spring.application.name=client-application

spring.cloud.config.import=optional:configserver:http://localhost:8888

Step 3: Open the main and create the RESTAPI endpoint of the application.

Go to src > main >java > org.example.clientapplication > ClientApplication and put the below code.

Step 4: Run the application

Once the Spring project is completed and successfully runs as a Spring application, it will start at port 8080.

Managing Configuration Testing:

Endpoint API:

GET http://localhost:8080/

Postman Output:

Health Endpoint:

Output:

Metrics Endpoint:

Output:

This example demonstrates the implementation of the configuration for the monitoring and logging of the microservices with Spring Cloud Config of the Spring Boot application.

In Microservices, Spring Cloud Server can play a crucial role in Spring microservices by providing centralized configuration management. It helps externalize configuration properties across all environments for applications, making them easier to manage and update without redeploying or restarting the applications. Monitoring and logging in the Spring Cloud Config Server are essential for understanding its operational health, troubleshooting issues, and ensuring that configuration changes propagate correctly to the client applications.
