In general, severity doesn't say much about the ... severity of the error/exception. So there are
messages with a low severity which are logged, and vice versa. As for level 15, it happens that this
level has no messages that are logged. Consider submitting at connect if you want this level to not
to be shown in the drop-down. Here's a query to show all errors which are logged (20 and higher are
logged regardless of is_event_logged column):
SELECT *
FROM sys.messages
WHERE (is_event_logged = 1 OR severity > 20)
AND language_id = 1033
ORDER BY severity, message_id
