spring-boot-admin


This is a simple admin interface for Spring Boot applications.

This application provides a simple GUI to administrate Spring Boot applications in some ways. At the moment it provides the following features for every registered application.

• Show name/id and version number
• Show health status
• Download main logfile
• Show details, like
• JVM & memory metrics
• Counter & gauge Metrics
• Datasource Metrics
• View Java, System- & Environment-properties
• Support for Spring Clouds postable /env- &/refresh-endpoint
• Easy loggerlevel management (for Logback)
• Interact with JMX-Beans
• View Threaddump
• View Traces
• Mail and desktop notification on status change
• Event journal of status changes (non persistent)

Server application

Add the following dependency to your pom.xml.

<dependency>
	<groupId>de.codecentric</groupId>
	<artifactId>spring-boot-admin-server</artifactId>
	<version>1.2.3</version>
</dependency>
<dependency>
	<groupId>de.codecentric</groupId>
	<artifactId>spring-boot-admin-server-ui</artifactId>
	<version>1.2.3</version>
</dependency>

Create the Spring Boot Admin Server with only one single Annotation.

@Configuration
@EnableAutoConfiguration
@EnableAdminServer
public class Application {
	public static void main(String[] args) {
		SpringApplication.run(Application.class, args);
	}
}

See also the example project in this repository.

For configuring Hazelcast support see spring-boot-admin-server or hazelcast-example project

Register / Discover client applications

To get all your boot applications shown in spring boot admin you have two choices:

1. either you include the spring-boot-admint-starter-client into your applications

or

2. you add a DiscoveryClient (e.g. Eureka) to your spring boot admin server.

Note: If you don't include the spring-boot-admin-starter-client the logfile won't be availible, due to the fact that the logfile endpoint won't be exposed.

Register client applications via spring-boot-admin-starter-client

Each application that want to register itself to the admin application has to include the spring-boot-admin-starter-client as dependency. This starter JAR includes some AutoConfiguration features that includes registering tasks, controller, etc.

<dependency>
	<groupId>de.codecentric</groupId>
	<artifactId>spring-boot-admin-starter-client</artifactId>
	<version>1.2.3</version>
</dependency>

Inside your configuration (e.g. application.properties) you also have to define the URL of the Spring Boot Admin Server, e.g.

spring.boot.admin.url=http://localhost:8080

For all configuration options see spring-boot-admin-starter-client

Discover client applications via DiscoveryClient

Just add spring-clouds @EnableDiscoveryClient annotation and include an appropriate implementation (e.g. Eureka) to your classpath.

@Configuration
@EnableAutoConfiguration
@EnableDiscoveryClient
@EnableAdminServer
public class SpringBootAdminApplication {
	public static void main(String[] args) {
		SpringApplication.run(SpringBootAdminApplication.class, args);
	}
}

<dependency>
	<groupId>org.springframework.cloud</groupId>
	<artifactId>spring-cloud-starter-eureka</artifactId>
	<version>1.0.3.RELEASE</version>
</dependency>

See the sample discovery sample project

Mail notification on status change

Configure a JavaMailSender using spring-boot-starter-mail and set a recipient:

		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-mail</artifactId>
		</dependency>

spring.mail.host=smtp.example.com
spring.boot.admin.notify.to=admin@example.com

For all configuration options see spring-boot-admin-server
