Spring Boot Admin Reference Guide

## 1. What is Spring Boot Admin? ##

Spring Boot Admin is a simple application to manage and monitor your [Spring Boot Applications][]. The applications register with our Spring Boot Admin Client (via http) or are discovered using Spring Cloud (e.g. Eureka). The UI is just an Angular.js application on top of the Spring Boot Actuator endpoints. In case you want to use the more advanced features (e.g. jmx-, loglevel-management), Jolokia must be included in the client application.

## 2. Getting started ##

### 2.1. Set up admin server ###

First you need to setup your server. To do this just setup a simple boot project (using [start.spring.io][] for example).

1. Add Spring Boot Admin Server and the UI to your dependencies:
 
 pom.xml
 
 <dependency>
 <groupId>de.codecentric</groupId>
 <artifactId>spring-boot-admin-server</artifactId>
 <version>1.3.3</version>
 </dependency>
 <dependency>
 <groupId>de.codecentric</groupId>
 <artifactId>spring-boot-admin-server-ui</artifactId>
 <version>1.3.3</version>
 </dependency>
2. Pull in the Boot Admin Server configuration via adding `@EnableAdminServer` to your configuration:
 
 @Configuration
 @EnableAutoConfiguration
 @EnableAdminServer
 public class SpringBootAdminApplication {
 public static void main(String[] args) {
 SpringApplication.run(SpringBootAdminApplication.class, args);
 }
 }

See also the [spring-boot-admin-sample][] project.

### 2.2. Register client applications ###

To register your application at the admin server (next referred as "clients"). Either you can include the `spring-boot-admin` client or use [Spring Cloud Discovery][] (e.g. Eureka)

#### 2.2.1. Register clients via spring-boot-admin-client ####

Each application that want to register itself to the admin has to include the Spring Boot Admin Client.

1. Add spring-boot-admin-starter-client to your dependencies:
 
 pom.xml
 
 <dependency>
 <groupId>de.codecentric</groupId>
 <artifactId>spring-boot-admin-starter-client</artifactId>
 <version>1.3.3</version>
 </dependency>
2. Trigger the contained AutoConfiguration and tell the client where to find the admin to register at:
 
 application.properties
 
 spring.boot.admin.url=http://localhost:8080

#### 2.2.2. Discover clients via Spring Cloud Discovery ####

If you already using Spring Cloud Discovery for your applications you don’t have to add the Spring Boot Admin Client to your applications. Just make the Spring Boot Admin Server a DiscoveryClient, the rest is done by our AutoConfiguration. The following steps are for using Eureka. Also have a look at the [Spring Cloud Netflix documentation][].

1. Add spring-cloud-starter-eureka to you dependencies:
 
 pom.xml
 
 <dependency>
 <groupId>org.springframework.cloud</groupId>
 <artifactId>spring-cloud-starter-eureka</artifactId>
 <version>1.0.6.RELEASE</version>
 </dependency>
2. Enable discovery by adding `@EnableDiscoveryClient` to your configuration:
 
 @Configuration
 @EnableAutoConfiguration
 @EnableDiscoveryClient
 @EnableAdminServer
 public class SpringBootAdminApplication {
 public static void main(String[] args) {
 SpringApplication.run(SpringBootAdminApplication.class, args);
 }
 }
3. Tell the Eureka client where to find the service registry:
 
 application.properties
 
 eureka.instance.client.serviceUrl.defaultZone: http://localhost:8761/eureka/

See also [spring-boot-admin-sample-discovery][].

## 3. Client applications ##

### 3.1. Show version in application list ###

To get the version show up in the admin’s application list you have to set `info.version`. For example using maven filtering during the build:

application.properties

info.version=@project.version@

### 3.2. JMX-bean management ###

To interact with JMX-beans in the admin UI you have to include [Jolokia][] in your application. In case you are using the`spring-boot-admin-starter-client` it will be pulled in for you, if not add Jolokia to your dependencies:

pom.xml

<dependency>
 <groupId>org.jolokia</groupId>
 <artifactId>jolokia-core</artifactId>
 </dependency>

### 3.3. Loglevel managment ###

Currently the loglevel management is only available for [Logback][]. It is accessed via JMX so [include Jolokia][] in your application. In addition you have configure Logback’s `JMXConfigurator`:

logback.xml

### 3.4. Spring Boot Admin Client ###

The Spring Boot Admin Client registers the application at the admin server. This is done by periodically doing a http post-request to the admin server providing informations about the application. It also adds Jolokia to your dependencies, so that JMX-beans are accessible via http, this is needed if you want to manage loglevels or JMX-beans via the admin UI.

### 4.1. Spring Cloud Discovery support ###

The Spring Boot Admin Server is capable of using Spring Clouds `DiscoveryClient` to discover applications. The advantage is that the clients don’t have to include the `spring-boot-admin-starter-client`. You just have to add a DiscoveryClient to your admin server - everything else is done by AutoConfiguration. The setup is explained [above][].

#### 4.1.1. Usage of discovery informations ####

The informations from the discovered services are converted by the `ServiceInstanceConverter`. Spring Boot Admin ships with a default and Eureka converter implementation. The correct one is selected by AutoConfiguration. You can use your own conversion by implementing the interface and adding the bean to your application context.

### 4.2. Hazelcast support ###

Spring Boot Admin Server supports cluster replication with Hazelcast. It is automatically enabled when a`HazelcastConfig`\- or `HazelcastInstance`\-Bean is present. You can also configure the Hazelcast instance to be persistent, to keep the status over restarts. Also have a look at the [Spring Boot support for Hazelcast][].

1. Add Hazelcast to your dependencies:
 
 pom.xml
 
 <dependency>
 <groupId>com.hazelcast</groupId>
 <artifactId>hazelcast</artifactId>
 </dependency>
2. Instantiate a HazelcastConfig:
 
 @Configuration
 @EnableAutoConfiguration
 @EnableAdminServer
 public class SpringBootAdminApplication {
 @Bean
 public Config hazelcastConfig() {
 return new Config().setProperty("hazelcast.jmx", "true")
 .addMapConfig(new MapConfig("spring-boot-admin-application-store")
 .setBackupCount(1)
 .setEvictionPolicy(EvictionPolicy.NONE))
 .addListConfig(new ListConfig("spring-boot-admin-event-store")
 .setBackupCount(1)
 .setMaxSize(1000));
 }
 
 public static void main(String[] args) {
 SpringApplication.run(SpringBootAdminApplication.class, args);
 }
 }

#### 4.3.5. Reminder notifications ####

To get reminders for down/offline applications you can add a `RemindingNotifier` to your `ApplicationContext`. The`RemindingNotifier` uses another `Notifier` as delegate to send the reminders.

How to configure reminders

@Configuration
    @EnableScheduling
    public class ReminderConfiguration {
        @Autowired
        private Notifier notifier;
    
        @Bean
        @Primary
        public RemindingNotifier remindingNotifier() {
            RemindingNotifier remindingNotifier = new RemindingNotifier(notifier);
            remindingNotifier.setReminderPeriod(TimeUnit.MINUTES.toMillis(5)); 
            return remindingNotifier;
        }
    
        @Scheduled(fixedRate = 6000L) 
        public void remind() {
            remindingNotifier().sendReminders();
        }
    }

## 5. FAQs ##

1.  Can I include spring-boot-admin into my business application?
    
    tl;dr You can, but you shouldn’t.  
    You can set `spring.boot.admin.context-path` to alter the path where the UI and REST-API is served, but depending on the complexity of your application you might get in trouble. On the other hand in my opinion it makes no sense for an application to monitor itself. In case your application goes down your monitoring tool also does.
2.  How do I customize the UI?
    
    You can only customize the UI by copying and modifying the source of `spring-boot-admin-ui` and adding your own module to your classpath.
