@splunknoob408, seems like you are setting up DB Connect on fresh installation of Splunk Enterprise as these are default indexes that are created in Splunk. You would want to create a new index for your DB Connect Data (or your Splunk App data, depending on the need).
OR the DB Connect Documentation for complete details: http://docs.splunk.com/Documentation/DBX/latest/DeployDBX/Createandmanagedatabaseinputs
Thank you, I will read the docs and watch the video. I did a tutorial for DB Connect, but I don't recall it explaining how to create the index -- I think it was already in the list because he was using standard Splunk log data.
