[SOLVED] How to make Javamelody use different port (Spring Boot+two HTTP ports exposed)

How to make Javamelody use different port (Spring Boot+two HTTP ports exposed)

I have Spring Boot web application. It exposes REST API on port 8080. It also exposes management port 8081 with Spring Boot Management endpoints (http://docs.spring.io/spring-boot/docs/current/reference/html/production-ready-monitoring.html). I do not have any custom Tomcat configuration to achieve that. I just have property management.port=8081 in my application.properties file.

I have JavaMelody configured as described in https://github.com/javamelody/javamelody/wiki/UserGuideAdvanced#spring-boot-app (I have my custom JavaMelodyConfiguration class, with org.springframework.boot.web.servlet.FilterRegistrationBean that registers net.bull.javamelody.MonitoringFilter).

@Bean
    public FilterRegistrationBean javaMelody() {
        final FilterRegistrationBean javaMelody = new FilterRegistrationBean();
        javaMelody.setFilter(new MonitoringFilter());
        javaMelody.setAsyncSupported(true);
        javaMelody.setDispatcherTypes(DispatcherType.REQUEST, DispatcherType.ASYNC);
        javaMelody.addUrlPatterns("/*");
        return javaMelody;
    }

With this configuration, Javamelody is exposed on port 8080 (business port). I would like to move it to 8081(management port). How to change that?

I use Spring Boot 1.4.2.RELEASE, javamelody 1.62.0

Solution

If the goal is to expose monitoring on management port starting from java melody version 1.76 is now much simpler.

You need Spring Boot 2.x, actuator and in yml or properties file:

management.server.port: {your custom port}
management.endpoints.web.exposure.include: {what you want normally}, monitoring
javamelody.management-endpoint-monitoring-enabled: true
