#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# function Find-DbaDatabaseGrowthEvent { <# .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 SQL Server name or SMO object representing the SQL Server to connect to. This can be a collection and receive pipeline input to allow the function to be executed against multiple SQL Server instances. .PARAMETER SqlCredential Allows you to login to servers using SQL Logins instead of Windows Authentication (AKA Integrated or Trusted). To use: $scred = Get-Credential, then pass $scred object to the -SqlCredential parameter. Windows Authentication will be used if SqlCredential is not specified. SQL Server does not accept Windows credentials being passed as credentials. To connect as a different Windows user, run PowerShell as that user. .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 vaules: Data, Log .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 Query Extracted from SQL Server Management Studio (SSMS) 2016.
