This metric monitors whether a server principal’s default database is offline. When you create a SQL Server server principal (formerly referred to as a server login) it has a default database setting that is used to assist in a connection request when no database is specified. For example, this means that the Accounts users can connect to the Accounts database by default. However, if that database goes offline and a connection is attempted, an error is presented to the user. Some users can cope with this, but others such as an unattended service account may have trouble.
