Audit succesfull logons , loging every 2 seconds

I created an audit to audit only succesfull logons. But the problem is, I did it in a test environment and it's loging a connection every second

Did I do something wrong ? I only selected SUCCESFULL LOGIN GROUP in the specification.

also is there a way to know how many audits for each file created?

and, is there a way to reduce the ammount of fields being audited?

EDIT: damm 2 weeks and I didnt find an answer for this.
