  • 1.  Backend in java application

    Posted Oct 29, 2018 04:58 AM

    Hi

     

    I am using APM 10.7 and have deployed a java agent on the tomcat server. I have also deployed a(.War) file in the tomcat webapps folder and also I am getting metrics regarding the front end...but how can I get the metrics for backend as in the database of the java application.

     

    Thanks

    Dear Community:

    Can you make additional suggestions to Imram?

     

    What is the following property set to?

    introscope.agent.automatic.backend.detection.enable

    This property enables and disables the agent ability to detect automatic backends.

     

    Thanks

    Hi Imran Ali Khan,

    Aside from the newer automatic backend detection, historically backends like Database connections are found from socket connection tracing (java.net.Socket). "TurnOn: SocketTracing" is enabled by default in toggles-typical.pbd & toggles-full,pbd so you should have it.

     

    Below is an example from my WebLogic Medrec application showing DB connection under Backends which is also under the Sockets/Client node. ("Unknown Driver" because APM does not have a tracer for the Derby DB.

     

    What are your Backends nodes showing - can you upload a screenshot?

     

    Thanks

    Hi Imran Ali Khan

    I see an NIO node (Java NIO sockets, also traced by agent) but no traditional Sockets node.

     

    Is this 10.7 agent the first time you have installed an APM agent for this Tomcat application?

     

    Is there definitely no clamp showing in APM Status Console or agent log ([WARN] [IntroscopeAgent.Agent] Absolute metric clamp of nnnnn reached, no more metrics can be created. Instrumentation on this application should be reduced.) ?

     

    What RDBMS is the application hitting at the backend?

     

    Thanks
