events not reflected in jmx add on

i have added jmx add-on to splunk and connected to the tomcat server via process id, however when i search for "sourcetype=jmx" it says 0 events returned. Also, i cannot see "jmx" as a datasource in "Data Summarry" - Process id is correct - Splunk Single Instance setup is on same server as tomcat application - Index is "Default" index Any help is appreciated
