Hi Siva,

Java Agent is for instrumenting the application and to capture performance metrics of the application

Hi Rajesh,

Thanks for your information.

I have added Java agent in my tomcat app server where my application is installed. Agent started successfully

and able to see application in web browser ui. But I am unable to see load on that application even though there is load on application.

Can you please tell the reason behind this.

Note: I am using trail version licence

Hi Siva,

Glad to hear this good news that there has been some progress on this case. The reason you are not seeing any load on the controller UI is there could not be any OOTB defined entry points which can suit your environment. However, could you please follow the steps listed here and send us latest agent logs, so that we can help you in defining custom entry rules for the load to be depicted on controller UI

1) Please enable find-entry-points node property to true. Please find attached screenshot to enable find-entry-points to true.

2) Generate some traffic on the application for say 5-10 mins

3) Zip up the logs and enclose it here

4) After that please change back find-entry-points node property to false

Thanks

Hi Siva,

Thanks for the logs. Unfortunately i didnot get whole zipped up agent logs to check for Byte code instrumentation. But i found that your license usage of java agent is exhausted and hence agent is complaining abut license limit hit.

Could you please sort out the license limit issues by stopping unwanted app agents from reporting, so that this JVM can use that license.

Please find the log snippet for the issue in detail.

Hi Rajesh,

Thanks for your help. Now I am able to see the load in Application console. For this I have changed the license which is not expired.

Thanks and Regards
