Spring-boot Actuator (Monitoring) configuration and use

In a production environment, the availability of services needs to be monitored in real time or regularly. The Spring-boot Actuator (monitoring) feature provides many of the interfaces required for monitoring. The simple configuration and use are as follows:
1, the introduction of dependency:
[HTML] view plain copy <dependency> <groupId>org.springframework.boot</groupId> & Lt;artifactid>spring-boot-starter-actuator</artifactid> </dependency>
This dependency is also required if the HTTP call is used:
[HTML] view plain copy <dependency> <groupId>org.springframework.boot</groupId> & Lt;artifactid>spring-boot-starter-web</artifactid> </dependency>
2. Configuration:

The HTTP port specified in APPLICATION.YML (if not specified, uses the same port as the server); Specifies that a check is removed (such as not monitoring Health.mail):

[plain] view plain copy server:port:8082 management:port:54001 health:mail:en Abled:false

3. Use: View the health indicator: http://localhost:54001/health
[plain] view plain copy {"status": "Up", "diskspace": {' status ': ' Up ', ' total ': 120031539200, "free": 33554337792 , "Threshold": 10485760}, "db": {"status": "Up", "DataSource1": {"status": "Up", "Database": "MySQL", "Hello": 1}, " DataSource2 ": {" status ":" Up "," Database ":" MySQL "," Hello ": 1}}}
4. Custom indicators:
4.1/health: Implements the Healthindicator interface in a class, and then implement the health () method in it:

Code:

[Java]  View plain  copy @SpringBootApplication    @EnableScheduling    public class  MySpringBootApplication implements HealthIndicator{       private  static logger logger = loggerfactory.getlogger (Myspringbootapplication.class);               public static void main ( String[] args)  {           springapplication.run ( Myspringbootapplication.class, args);            Logger.info ("my spring boot application started");       }           /**       *  when the/health interface is called, Returns one more attribute: ' myspringbootapplication ': {' status ': ' Up ', ' Hello ': ' World '}       */    &NBSP;&NBSP;   @Override        public health health ()  {
