Why is SBA JMX Bean Management reporting an error?

Question

Versions:

• Spring Boot 2.1.0
• Spring Boot Admin 2.1.1

I have everything working with my Spring Boot app reporting to Spring Boot Admin. There is just 1 piece not working and that is JMX Bean Management. From the docs:

To interact with JMX-beans in the admin UI you have to include Jolokia in your application. As Jolokia is servlet based there is no support for reactive applications. 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.

I understand it does not work with Reactive WebFlux but I am using Servlet Based example using Undertow as my servlet container. Configuration in pom.xml:

    <dependency>
        <groupId>de.codecentric</groupId>
        <artifactId>spring-boot-admin-starter-server</artifactId>
    </dependency>
    <dependency>
        <groupId>de.codecentric</groupId>
        <artifactId>spring-boot-admin-starter-client</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-tomcat</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-undertow</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-security</artifactId>
    </dependency>

And as i stated everything is working except 1 thing and that is JMX control. I get the following error and I can't find any reason or logging as to why? Any help would be appreciated!

Answer 1

Start your program with following parameters:

-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.local.only=false
-Dcom.sun.management.jmxremote.port=1099

And (if using docker/kubernetes) expose port 1099
