Enable Tomcat’s MBean Registry

Embedded Tomcat’s MBean registry is disabled by default. This minimizes Tomcat’s memory footprint. If you want to use Tomcat’s MBeans, for example so that they can be used by Micrometer to expose metrics, you must use the server.tomcat.mbeanregistry.enabled property to do so, as shown in the following example:

Properties
YAML

server.tomcat.mbeanregistry.enabled=true

server:
  tomcat:
    mbeanregistry:
      enabled: true
