function Get-DbaDatabaseSpace { <# .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. The function can accept a single instance or multiple instances. By default, only user dbs will be shown, but using the IncludeSystemDBs switch will include system databases File free space script borrowed and modified from Glenn Berry's DMV scripts (http://www.sqlskills.com/blogs/glenn/category/dmv-queries/) .PARAMETER SqlInstance SqlInstance name or SMO object representing the SQL Server to connect to. This can be a collection and receive pipeline input .PARAMETER SqlCredential PSCredential object to connect under. If not specified, current Windows login will be used. .PARAMETER Database The database(s) to process - this list is auto-populated from the server. If unspecified, all databases will be processed. .PARAMETER ExcludeDatabase The database(s) to exclude - this list is auto-populated from the server .PARAMETER IncludeSystemDBs Switch parameter that when used will display system database information .PARAMETER Silent Replaces user friendly yellow warnings with bloody red exceptions of doom! Use this if you want the function to throw terminating errors you want to catch. .EXAMPLE Get-DbaDatabaseSpace -SqlInstance localhost Returns all user database files and free space information for the local host .EXAMPLE Get-DbaDatabaseSpace -SqlInstance localhost | Where-Object {$_.PercentUsed -gt 80} Returns all user database files and free space information for the local host. Filters the output object by any files that have a percent used of greater than 80%. .EXAMPLE 'localhost','localhost\namedinstance' | Get-DbaDatabaseSpace Returns all user database files and free space information for the localhost and localhost\namedinstance SQL Server instances. Processes data via the pipeline. .EXAMPLE Get-DbaDatabaseSpace -SqlInstance localhost -Database db1, db2 Returns database files and free space information for the db1 and db2 on localhost. .NOTES Author: Michael Fal (@Mike_Fal), http://mikefal.net Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 .LINK https://dbatools.io/Get-DbaDatabaseSpace #> [CmdletBinding()] param ([parameter(ValueFromPipeline, Mandatory = $true)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]] $SqlInstance, [System.Management.Automation.PSCredential] $SqlCredential, [Alias("Databases")] [object[]] $Database, [object[]] $ExcludeDatabase, [switch] $IncludeSystemDBs, [switch] $Silent ) begin { Write-Message -Level System -Message "Bound parameters: $($PSBoundParameters.Keys -join ", ")" $sql = "SELECT SERVERPROPERTY('MachineName') AS ComputerName, ISNULL(SERVERPROPERTY('InstanceName'), 'MSSQLSERVER') AS InstanceName, SERVERPROPERTY('ServerName') AS SqlInstance, DB_NAME() as DBName ,f.name AS [FileName] ,fg.name AS [Filegroup] ,f.physical_name AS [PhysicalName] ,f.type_desc AS [FileType] ,CAST(CAST(FILEPROPERTY(f.name, 'SpaceUsed') AS int)/128.0 AS FLOAT) as [UsedSpaceMB] ,CAST(f.size/128.0 - CAST(FILEPROPERTY(f.name, 'SpaceUsed') AS int)/128.0 AS FLOAT) AS [FreeSpaceMB] ,CAST((f.size/128.0) AS FLOAT) AS [FileSizeMB] ,CAST((FILEPROPERTY(f.name, 'SpaceUsed')/(f.size/1.0)) * 100 as FLOAT) as [PercentUsed] ,CAST((f.growth/128.0) AS FLOAT) AS [GrowthMB] ,CASE is_percent_growth WHEN 1 THEN 'pct' WHEN 0 THEN 'MB' ELSE 'Unknown' END AS [GrowthType] ,CASE f.max_size WHEN -1 THEN 2147483648.
