java_agent not discovering the JDBC calls

[Akshay.Nimbal]

Hi,

We are running many applications with JAVA_AGENT and out of those, a few applications are discovering the JDBC calls and a few are not discovering the JDBC backend. I even tried to manually add a custom discovery with rule of matching URL. What all other factors impacting this and anything needs to be changed? Have attached the samples here.

Note:

1. Both apps are using same version of MySQL connector jar.  mysql-connector-java : 5.1.49

For the application where the JDBC details and queries are captured. 

For the similar application where JDBC details are not captured.

Note: 

1. For the app where details are captured is a web-app where business-transaction are present. but for the app where this is not captured is a core java app without transaction. ( More like a monitoring app ). Does this have any impact?

Thanks & Regards.

After discussing with AppDynamics support, we found these observations and solution.

The reason you are not observing any database calls is that not a single Business Transaction has been detected. The agent only detects outgoing calls if they occur within the context of a Business Transaction (BT).
 
Next steps: 
Please apply the below-mentioned node property:

Name: find-entry-points
Type: Boolean
Value: True

This property will enable a feature that will recognize all the potential entry points that can be created as custom match rules.

For more information on how to set/change node property please check the reference doc:

• App Agent Node Properties

Once you will change the property value, collect the Agent debug log files and share them with us. Then revert the change.
