I want to add reporting capabilities for tasks completed. but I don't know how to develop.

I have already installed AWX.
but where do I have to start from?
from open source code or only using GUI?
I am a developer but not experienced such field.
I am looking forward to your reply.

Hi YiCheng Song

Logging can be configured from the GUI, just start by following the guides here: https://docs.ansible.com/ansible-tower/latest/html/administration/logging.html
You want to select a log aggregator where you’ll send all the job and stream data. You can then use that or other dashboarding tools for your reporting.

Phil.
