-ExcludeDatabase

The database(s) to exclude - this list is auto-populated from the server

-Threshold

Allows you to specify a minimum % of the seed range being utilized. This can be used to ignore seeds that have only utilized a small fraction of the range.

Alias
Required False
Pipeline false
Default Value 0
-ExcludeSystem

Allows you to suppress output on system databases

Alias
Required False
Pipeline false
Default Value False
-EnableException

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

Alias
Required False
Pipeline false
Default Value False
