An overview of the

In my previous article, “Spring Boot Application Monitoring in Action,” I explained how to use the Spring Boot Admin 1.5.x release to visually monitor Spring Boot applications. Now that Spring Boot Admin has been updated to version 2.0, you can monitor the current hot Spring Boot 2.0 and Spring Cloud Finchley.RELEASE, so here’s a look and see!

New features of Spring Boot Admin 2.0

Spring Boot Admin 2.0 has a lot of changes, please refer to the official website for details, here are a few main:

  • I rewrote the UI with vue. js, too pretty to be real

  • Spring Security-based authentication is directly integrated without introducing third-party modules

  • Added the monitoring support for session endpoint

And so on…

Here is the actual test to feel the operation!

Set up the Spring Boot Admin Server

  • Create a SpringBoot 2.0.3 RELEASE project and add dependencies
<dependencies> <dependency> <groupId>de.codecentric</groupId> <artifactId>spring-boot-admin-starter-server</artifactId> < version > 2.0.1 < / version > < / dependency > < the dependency > < groupId > DE. Codecentric < / groupId > < artifactId > spring - the boot - admin server - UI < / artifactId > < version > 2.0.1 < / version > < / dependency > < the dependency > <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies>Copy the code
  • Apply the main class to add annotations
@SpringBootApplication
@EnableAdminServer
public class SbaServer20Application {

    public static void main(String[] args) {
        SpringApplication.run(SbaServer20Application.class, args);
    }
}
Copy the code
  • Start the Spring Boot Admin Server

Browser open localhost:8080, you can see the small fresh page

As you can see, this UI change is a far cry from the 1.5.X era, when the number of monitored apps was 0.

Let’s create an example of Spring Boot 2.0 to monitor.

Example Create the Spring Boot Admin Client

Again, we create a Spring Boot 2.0.3.RELEASE application and add it to the Spring Boot Admin for monitoring

  • Add dependencies to POM.xml
<dependencies> <dependency> <groupId>de.codecentric</groupId> <artifactId>spring-boot-admin-starter-client</artifactId> < version > 2.0.1 < / version > < / dependency > < the dependency > < groupId > org. Springframework. Boot < / groupId > <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies>Copy the code
  • Editing a Configuration File
server.port=8081
spring.application.name=Spring Boot Client
spring.boot.admin.client.url=http://localhost:8080
management.endpoints.web.exposure.include=*
Copy the code
  • Example Start the Spring Boot Admin Client

At this point, the message that the application is online is pushed to the Spring Boot Admin page:

The actual experiment

Once the monitored application is online, we go to the Spring Boot Admin page to play around with it

  • Wallboard is a little fresh

  • An overview of the Applications

  • The Applications online log is clear

  • Applications Details

  • Metrics

  • Environment

  • JMX

  • Threads

  • Http Traces
