function Import-DbaXESessionTemplate { <# .SYNOPSIS Imports a new XESession XML Template .DESCRIPTION Imports a new XESession XML Template either from our repo or a file you specify .PARAMETER SqlInstance The SQL Instances that you're connecting to. .PARAMETER SqlCredential Credential object used to connect to the SQL Server as a different user .PARAMETER Name The Name of the session .PARAMETER Path The path to the xml file or files .PARAMETER Template From one of the templates we curated for you (tab through -Template to see options) .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 = "$TargetFilePath\file.xel". Only specify the directory, not the file itself. This path is relative to the destination directory .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 .LINK https://dbatools.io/Import-DbaXESessionTemplate .EXAMPLE Import-DbaXESessionTemplate -SqlInstance sql2017 -Template db_query_wait_stats Creates a new XESession named db_query_wait_stats from our repo to the SQL Server sql2017 .EXAMPLE Import-DbaXESessionTemplate -SqlInstance sql2017 -Template db_query_wait_stats -Name "Query Wait Stats" Creates a new XESession named "Query Wait Stats" using the db_query_wait_stats template .EXAMPLE Get-DbaXESession -SqlInstance sql2017 -Session db_ola_health | Remove-DbaXESession Import-DbaXESessionTemplate -SqlInstance sql2017 -Template db_ola_health | Start-DbaXESession Imports a session if it exists then recreates it using a template .EXAMPLE Get-DbaXESessionTemplate | Out-GridView -PassThru | Import-DbaXESessionTemplate -SqlInstance sql2017 Allows you to select a Session template then import to an instance named sql2017 #> [CmdletBinding()] param ( [parameter(Mandatory, ValueFromPipeline)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [string]$Name, [parameter(ValueFromPipelineByPropertyName)] [Alias("FullName")] [string[]]$Path, [string[]]$Template, [string]$TargetFilePath, [switch]$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 $Tempalte.Count -gt 1) -and (Test-Bound -ParameterName Template)) { Stop-Function -Message "Name cannot be specified with multiple files or templates because the Session will already exist" } foreach ($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" #
