Java Management Extensions (JMX) provide a standard mechanism to monitor and manage
applications. By default, Spring Boot exposes management endpoints as JMX MBeans under
the org.springframework.boot domain.
The name of the MBean is usually generated from the id of the endpoint. For example the
health endpoint is exposed as org.springframework.boot:type=Endpoint,name=Health.
If your application contains more than one Spring ApplicationContext, you may find that
names clash. To solve this problem, you can set the
management.endpoints.jmx.unique-names property to true so that MBean names are always
unique.
You can also customize the JMX domain under which endpoints are exposed. The following
settings show an example of doing so in application.properties:
management.endpoints.jmx.domain=com.example.myapp management.endpoints.jmx.unique-names=true
If you do not want to expose endpoints over JMX, you can set the
endpoints.default.jmx.enabled property to false, as shown in the following example:
endpoints.default.jmx.enabled=falseJolokia is a JMX-HTTP bridge that provides an alternative method of accessing JMX beans.
To use Jolokia, include a dependency to org.jolokia:jolokia-core. For example, with
Maven, you would add the following dependency:
<dependency> <groupId>org.jolokia</groupId> <artifactId>jolokia-core</artifactId> </dependency>
Jolokia can then be accessed by using /application/jolokia on your management HTTP
server.
Jolokia has a number of settings that you would traditionally configure using servlet
parameters. With Spring Boot, you can use your application.properties. Prefix the
parameter with management.jolokia.config., as shown in the following example:
management.jolokia.config.debug=true
