Ideally, you should have chosen to install the default SQL instance which comes along with DLO and thereby isolating this instance from your production ones. Makes things simpler :)
I cannot go into detailed internal specifics, however the view which appears in the UI is queried from the DB. Having the same account for 2 different softwares (DLO and SQL in this case) makes lots of things easier.
EDIT**
I just re-read the original post. What type of security & performance reasons caused you to move from the default SQL instance to another one ?
