 Issue:

 Missing expected Frontends.
 

 

 Environment: 

 This can occur in any 10.x Java Agent.
 
 

 Cause:

 Conflict with the enabled BRTM extension missing a required file.  Having the brtm.pbd uncommented within the agent directives enables tracers that require the file BrtmExt.jar.  When this file is missing with brtm.pbd called as a directive, no Frontends will be seen.   
 
 Note: The brtm.pbd is typically called from the appserver_tracelevel.pbl.  For example, for a tomcat agent it would be tomcat_typical.pbl, tomcat_full.pbl and by default it is commented out.
 

 

 Resolution/Workaround: 

 Assuming that brtm.pbd is called. 
 1. Stop the agent.  
 2. Navigate to the AGENT INSTALL DIR\core\ext
 3. Copy over BrtmExt.jar ( this jar file is typically located under AGENT INSTALL DIR\examples\APM\BRTM\ext
 4. Start the agent.

 

 Additional Information: 

 This behavior will only be present on 10.x Java Agents.
