jUDDI also has some simple monitoring abilities. As of JBoss ESB 4.10, jUDDI provided MBeans with details on how many queries were processed for every single API method, what the overall processing time was per method, and how many successful and failed queries were launched. These counts, while simple, give you the opportunity to see which API (Inquiry, Security, or Publish) and method-costly queries might be appearing on, and where the bulk of the queries and query time is spent.
With your ESB Server running, browse to http://localhost:8080/jmx-console, and then browse down to the apache.juddi section. A counter MBean is listed for each of the UDDI APIs; click on the apache.juddi:counter=org.apache.juddi.api.impl.UDDIInquiryImpl MBean.
