Go to Admin → Config and add/update the cwmp.debug to DeviceID.ID = "<your_acs_id>" then look in the genieacs-debug.yaml file. The location of which will be in your /opt/genieacs/genieacs.env file. If you do not have an entry for GENIEACS_DEBUG_FILE in the genieacs.env, then add the entry and point it to a location the ACS has write permissions to. You will need to restart the CWMP process for the change to take effect.
