function Import-DbaXESessionTemplate { <# .SYNOPSIS Imports a new XESession XML Template .DESCRIPTION Imports a new XESession XML Template either from the dbatools repository or a file you specify. .PARAMETER SqlInstance Target SQL Server. You must have sysadmin access and server version must be SQL Server version 2008 or higher. .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 $scred object to the -SqlCredential parameter. Windows Authentication will be used if SqlCredential is not specified. SQL Server does not accept Windows credentials being passed as credentials. To connect as a different Windows user, run PowerShell as that user. .PARAMETER Name The Name of the session to create. .PARAMETER Path The path to the xml file or files for the session(s). .PARAMETER Template Specifies the name of one of the templates from the dbatools repository. Press tab to cycle through the provided templates. .PARAMETER TargetFilePath By default, files will be created in the default xel directory. Use TargetFilePath to change all instances of filename = "file.xel" to filename = "$TargetFilePath\file.xel". Only specify the directory, not the file itself. This path is relative to the destination directory .PARAMETER TargetFileMetadataPath By default, files will be created in the default xem directory. Use TargetFileMetadataPath to change all instances of filename = "file.xem" to filename = "$TargetFilePath\file.xem". Only specify the directory, not the file itself. This path is relative to the destination directory .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Tags: ExtendedEvent, XE, Xevent Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Import-DbaXESessionTemplate .EXAMPLE Import-DbaXESessionTemplate -SqlInstance sql2017 -Template db_query_wait_stats Creates a new XESession named db_query_wait_stats from the dbatools repository to the SQL Server sql2017. .EXAMPLE Import-DbaXESessionTemplate -SqlInstance sql2017 -Template db_query_wait_stats -Name "Query Wait Stats" Creates a new XESession named "Query Wait Stats" using the db_query_wait_stats template. .EXAMPLE Get-DbaXESession -SqlInstance sql2017 -Session db_ola_health | Remove-DbaXESession Import-DbaXESessionTemplate -SqlInstance sql2017 -Template db_ola_health | Start-DbaXESession Imports a session if it exists, then recreates it using a template. .EXAMPLE Get-DbaXESessionTemplate | Out-GridView -PassThru | Import-DbaXESessionTemplate -SqlInstance sql2017 Allows you to select a Session template then import to an instance named sql2017. #> [CmdletBinding()] param ( [parameter(Mandatory, ValueFromPipeline)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [string]$Name, [parameter(ValueFromPipelineByPropertyName)] [Alias("FullName")] [string[]]$Path, [string[]]$Template, [string]$TargetFilePath, [string]$TargetFileMetadataPath, [switch]$EnableException ) begin { $metadata = Import-Clixml "$script:PSModuleRoot\bin\xetemplates-metadata.xml" } process { if ((Test-Bound -ParameterName Path -Not) -and (Test-Bound -ParameterName Template -Not)) { Stop-Function -Message "You must specify Path or Template." } if (($Path.Count -gt 1 -or $Template.Count -gt 1) -and (Test-Bound -ParameterName Template)) { Stop-Function -Message "Name cannot be specified with multiple files or templates because the Session will already exist." } foreach ($instance in $SqlInstance) { try { Write-Message -Level Verbose -Message "Connecting to $instance." $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential -MinimumVersion 11 } catch { Stop-Function -Message "Failure" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } $SqlConn = $server.ConnectionContext.SqlConnectionObject $SqlStoreConnection = New-Object Microsoft.SqlServer.Management.Sdk.Sfc.SqlStoreConnection $SqlConn $store = New-Object Microsoft.SqlServer.Management.XEvent.XEStore $SqlStoreConnection foreach ($file in $template) { $templatepath = "$script:PSModuleRoot\bin\xetemplates\$file.xml" if ((Test-Path $templatepath)) { $Path += $templatepath } else { Stop-Function -Message "Invalid template ($templatepath does not exist)." -Continue } } foreach ($file in $Path) { if ((Test-Bound -Not -ParameterName TargetFilePath)) { Write-Message -Level Verbose -Message "Importing $file to $instance" try { $xml = [xml](Get-Content $file -ErrorAction Stop) } catch { Stop-Function -Message "Failure" -ErrorRecord $_ -Target $file -Continue } } else { Write-Message -Level Verbose -Message "TargetFilePath specified, changing all file locations in $file for $instance."
