Hi there and welcome to the Graylog Community.
For folks to better help you, can you try adding a bit more to your question? I’ll refer you to How to Post a Question in the Community that Gets Responses, which outlines the things that are generally needed when asking a question in the forum that will get you a quick answer.
With that said, have you tried looking at the built-in sources dashboard to see if that surfaced any useful information?
