The agent doesn’t correctly query the following Tomcat JMX metrics when using embedded Tomcat with SpringBoot:
type=DataSourcetype=ThreadPooltype=ManagerWe add Tomcat JMX values for the above categories if the server was started via one of the following two methods:
It appears that when using embedded Tomcat with Spring Boot
StandardServerdoes get instrumented properly:By default, embedded Tomcat JMX is disabled by Spring Boot. In
application.propertiesTomcat mbeans need to be enabled by adding:server.tomcat.mbeanregistry.enabled=trueThe problem though is that the Mbean group namespaces are different, standalone Tomcat uses the prefix
Catalinafor queries whereas embedded Tomcat uses the prefixTomcat. Ourtomcat-jmxinstrumentation only queries MBeans with theCatalinaprefix thus queries initiated by embedded Tomcat fail due to an incorrect group name.Standalone Tomcat JMX:
Embedded Tomcat JMX
For now, the recommended workaround would be to utilize Custom JMX instrumentation by YAML and create a dashboard to view the metrics.
