In some installations, certain system databases may not be accessible — for example, the model database can be inaccessible if Microsoft SQL Server is installed on AWS. Previously, this situation caused monitoring errors.

Starting with this release, you can configure the monitoring to ignore such databases. Currently, the following system databases can be excluded: model, master, msdb and tempdb using GUI or editing config file entry exclude_databases, which represents the list of strings in config section connection.
