How do I enable DEBUG level logging?

What are the steps to enabling DEBUG mode for logging?

Updated on 7/26/18


Most AppDynamics app agents use INFO level logging by default. Sometimes, it is useful to collect logs with DEBUG level logging—for example:

  • when confirming life cycle phases to debug configuration issues, or
  • when AppDynamics Support requests DEBUG logs. 

Once DEBUG mode is enabled, apply load on the application and collect the debug logs.

I have tried to enable the debug log without success... the radio button is being disabled.

Can anyone help me? Thanks.





   It seems that you do not have permissions to capture logs.

   Please ref# the below doc# and enable the permissions to collect debug logs.







I have read through the document and I am pretty sure that my account has the permission.
