In a Classic Java App, JMX metrics appear correctly under the application and externalid of the metrics is the appserver itself which is correct for Services creation, however in UMA, JMX metrics appear under "projects>pods>containers" and externalId and vertex is the kubernetes node (below screenshot) which affects correlation and Services Creation
None at present time.
Enhancement Request # DE660755 has been created to report UMA JavaAgent metrics at the application level similar to the Classic Java Agent. For an update contact Broadcom Support
