function Get-DbaDbSpace { <# .SYNOPSIS Returns database file space information for database files on a SQL instance. .DESCRIPTION This function returns database file space information for a SQL Instance or group of SQL Instances. Information is based on a query against sys.database_files and the FILEPROPERTY function to query and return information. File free space script borrowed and modified from Glenn Berry's DMV scripts (http://www.sqlskills.com/blogs/glenn/category/dmv-queries/) .PARAMETER SqlInstance Specifies the SQL Server instance(s) to scan. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Database Specifies the database(s) to process. Options for this list are auto-populated from the server. If unspecified, all databases will be processed. .PARAMETER ExcludeDatabase Specifies the database(s) to exclude from processing. Options for this list are auto-populated from the server. .PARAMETER IncludeSystemDBs If this switch is enabled, system databases will be processed. By default, only user databases are processed. .PARAMETER 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. .NOTES Tags: Database, Space, Storage Author: Michael Fal (@Mike_Fal), http://mikefal.net Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaDbSpace .EXAMPLE PS C:\> Get-DbaDbSpace -SqlInstance localhost Returns all user database files and free space information for the localhost. .EXAMPLE PS C:\> Get-DbaDbSpace -SqlInstance localhost | Where-Object {$_.PercentUsed -gt 80} Returns all user database files and free space information for the local host.
