Troubleshooting Spring Boot Admin Log Level Changes: A Complete Guide

If you've been working with Spring Boot Admin and find yourself unable to change the log levels of your application at runtime, you're not alone. Many developers encounter this issue, especially when migrating settings from example projects or sample applications to their own. This guide aims to help you understand why this might happen and how to effectively troubleshoot and solve the problem.

The Problem Statement

In your Spring Boot application, you're trying to modify the logging levels through the Spring Boot Admin interface. Although you can see your application and its properties within Spring Boot Admin, activating the debug button for loggers fails, returning the message: "Setting ClassName to debug failed."

The core issue often lies in the configuration of security settings in your application. Let's dissect your current configuration and see how to resolve this.

Understanding the Configuration

Your application.yml settings look structured and mostly correct, but the Web Security configuration could be limiting some of the functionalities needed for Spring Boot Admin to change log levels effectively.

Key Sections of Your Configuration

Spring Boot Admin Client Configuration:

This section connects your application to the Spring Boot Admin server.

Security Configuration:
Your WebSecurityConfig.java has settings that dictate who can access various parts of your application:

The /actuator/** endpoint is crucial as it serves the management and monitoring capabilities needed by Spring Boot Admin.

The Solution

The good news is that resolving the log level modification issue is often straightforward. To enable the log level changes, you need to adjust the CSRF (Cross-Site Request Forgery) protection in your security configuration. By disabling CSRF protection, you allow Spring Boot Admin to change the log levels without being restricted by security constraints.

Steps to Implement the Solution

Open your WebSecurityConfig.java file.

Locate the configure method where you set the HTTP security.

Add the following line to disable CSRF protection:

Your updated WebSecurityConfig.java should look something like this:

Conclusion

By disabling CSRF protection in your WebSecurityConfig.java, you should now be able to change the log levels using the Spring Boot Admin interface seamlessly. Remember to test after making these changes to ensure everything is functioning as expected.

If you continue experiencing issues, double-check other configurations or consult the Spring Boot Admin documentation and community forums for additional support.
