Just above that table, you should see 4 drop-downs pertaining to SCCM package status messages...

If you click those drop-down lists, you'll see the status messages that are selected for each (success, failure, collection cleanup, and rerun advertisement). You can select or deselect whichever messages you want for each category, but I don't really recommend changing the defaults. These values are stored in the database (WD_AppSettings) as a comma-separated list of integers.
