#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# function Find-DbaDbGrowthEvent { <# .SYNOPSIS Finds any database AutoGrow events in the Default Trace. .DESCRIPTION Finds any database AutoGrow events in the Default Trace. The following events are included: 92 - Data File Auto Grow 93 - Log File Auto Grow 94 - Data File Auto Shrink 95 - Log File Auto Shrink .PARAMETER SqlInstance The target SQL Server instance or instances. This can be a collection and receive pipeline input to allow the function to be executed against multiple SQL Server instances. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .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 EventType Provide a filter on growth event type to filter the results. Allowed values: Growth, Shrink .PARAMETER FileType Provide a filter on file type to filter the results. Allowed values: Data, Log .PARAMETER UseLocalTime Return the local time of the instance instead of converting to UTC. .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: AutoGrow,Growth,Database Author: Aaron Nelson Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT Query Extracted from SQL Server Management Studio (SSMS) 2016. .LINK https://dbatools.io/Find-DbaDatabaseGrowthEvent .EXAMPLE PS C:\> Find-DbaDatabaseGrowthEvent -SqlInstance localhost Returns any database AutoGrow events in the Default Trace with UTC time for the instance for every database on the localhost instance. .EXAMPLE PS C:\> Find-DbaDatabaseGrowthEvent -SqlInstance localhost -UseLocalTime Returns any database AutoGrow events in the Default Trace with the local time of the instance for every database on the localhost instance. .EXAMPLE PS C:\> Find-DbaDatabaseGrowthEvent -SqlInstance ServerA\SQL2016, ServerA\SQL2014 Returns any database AutoGrow events in the Default Traces for every database on ServerA\sql2016 & ServerA\SQL2014. .EXAMPLE PS C:\> Find-DbaDatabaseGrowthEvent -SqlInstance ServerA\SQL2016 | Format-Table -AutoSize -Wrap Returns any database AutoGrow events in the Default Trace for every database on the ServerA\SQL2016 instance in a table format. .EXAMPLE PS C:\> Find-DbaDatabaseGrowthEvent -SqlInstance ServerA\SQL2016 -EventType Shrink Returns any database Auto Shrink events in the Default Trace for every database on the ServerA\SQL2016 instance. .EXAMPLE PS C:\> Find-DbaDatabaseGrowthEvent -SqlInstance ServerA\SQL2016 -EventType Growth -FileType Data Returns any database Auto Growth events on data files in the Default Trace for every database on the ServerA\SQL2016 instance. #> [CmdletBinding()] param ( [parameter(Mandatory, ValueFromPipeline)] [Alias("ServerInstance", "SqlServer")] [DbaInstance[]]$SqlInstance, [PSCredential]$SqlCredential, [Alias("Databases")] [object[]]$Database, [object[]]$ExcludeDatabase, [ValidateSet('Growth', 'Shrink')] [string]$EventType, [ValidateSet('Data', 'Log')] [string]$FileType, [switch]$UseLocalTime, [Alias('Silent')] [switch]$EnableException ) begin { $eventClass = New-Object System.Collections.ArrayList 92..95 | ForEach-Object { $null = $eventClass.Add($_) } if (Test-Bound 'EventType', 'FileType') { switch ($FileType) { 'Data' { <# should only contain events for data: 92 (grow), 94 (shrink) #> $eventClass.Remove(93) $eventClass.Remove(95) } 'Log' { <# should only contain events for log: 93 (grow), 95 (shrink) #> $eventClass.Remove(92) $eventClass.Remove(94) } } switch ($EventType) { 'Growth' { <# should only contain events for growth: 92 (data), 93 (log) #> $eventClass.Remove(94) $eventClass.Remove(95) } 'Shrink' { <# should only contain events for shrink: 94 (data), 95 (log) #> $eventClass.Remove(92) $eventClass.Remove(93) } } } $eventClassFilter = $eventClass -join "," $sql = " BEGIN TRY IF (SELECT CONVERT(INT,[value_in_use]) FROM sys.configurations WHERE [name] = 'default trace enabled' ) = 1 BEGIN DECLARE @curr_tracefilename VARCHAR(500);
