function Copy-DbaExtendedEvent { <# .SYNOPSIS Migrates SQL Extended Event Sessions except the two default sessions, AlwaysOn_health and system_health. .DESCRIPTION Migrates SQL Extended Event Sessions except the two default sessions, AlwaysOn_health and system_health. By default, all non-system Extended Events are migrated. .PARAMETER Source Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2000 or higher. .PARAMETER SourceSqlCredential 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 -SourceSqlCredential parameter. Windows Authentication will be used if SourceSqlCredential 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 Destination Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2000 or higher. .PARAMETER DestinationSqlCredential Allows you to login to servers using SQL Logins instead of Windows Authentication (AKA Integrated or Trusted). To use: $dcred = Get-Credential, then pass this $dcred to the -DestinationSqlCredential parameter. Windows Authentication will be used if DestinationSqlCredential 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 XeSession The Extended Event Session(s) to process. This list is auto-populated from the server. If unspecified, all Extended Event Sessions will be processed. .PARAMETER ExcludeXeSession The Extended Event Session(s) to exclude. This list is auto-populated from the server. .PARAMETER WhatIf If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run. .PARAMETER Confirm If this switch is enabled, you will be prompted for confirmation before executing any operations that change state. .PARAMETER Silent If this switch is enabled, the internal messaging functions will be silenced. .PARAMETER Force If this switch is enabled, existing Extended Events sessions on Destination with matching names from Source will be dropped. .NOTES Tags: Migration, ExtendedEvent, XEvent Author: Chrissy LeMaire (@cl), netnerds.net Requires: sysadmin access on SQL Servers 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/Copy-DbaExtendedEvent .EXAMPLE Copy-DbaExtendedEvent -Source sqlserver2014a -Destination sqlcluster Copies all Extended Event sessions from sqlserver2014a to sqlcluster using Windows credentials. .EXAMPLE Copy-DbaExtendedEvent -Source sqlserver2014a -Destination sqlcluster -SourceSqlCredential $cred Copies all Extended Event sessions from sqlserver2014a to sqlcluster using SQL credentials for sqlserver2014a and Windows credentials for sqlcluster. .EXAMPLE Copy-DbaExtendedEvent -Source sqlserver2014a -Destination sqlcluster -WhatIf Shows what would happen if the command were executed. .EXAMPLE Copy-DbaExtendedEvent -Source sqlserver2014a -Destination sqlcluster -XeSession CheckQueries, MonitorUserDefinedException Copies only the Extended Events named CheckQueries and MonitorUserDefinedException from sqlserver2014a to sqlcluster. #> [CmdletBinding(DefaultParameterSetName = "Default", SupportsShouldProcess = $true)] param ( [parameter(Mandatory = $true)] [DbaInstanceParameter]$Source, [parameter(Mandatory = $true)] [DbaInstanceParameter]$Destination, [PSCredential] $SourceSqlCredential, [PSCredential] $DestinationSqlCredential, [object[]]$XeSession, [object[]]$ExcludeXeSession, [switch]$Force, [switch]$Silent ) begin { $sourceServer = Connect-SqlInstance -SqlInstance $Source -SqlCredential $SourceSqlCredential -MinimumVersion 10 $destServer = Connect-SqlInstance -SqlInstance $Destination -SqlCredential $DestinationSqlCredential -MinimumVersion 10 $source = $sourceServer.DomainInstanceName $destination = $destServer.DomainInstanceName } process { $sourceSqlConn = $sourceServer.ConnectionContext.SqlConnectionObject $sourceSqlStoreConnection = New-Object Microsoft.SqlServer.Management.Sdk.Sfc.SqlStoreConnection $sourceSqlConn $sourceStore = New-Object Microsoft.SqlServer.Management.XEvent.XEStore $sourceSqlStoreConnection $destSqlConn = $destServer.ConnectionContext.SqlConnectionObject $destSqlStoreConnection = New-Object Microsoft.SqlServer.Management.Sdk.Sfc.SqlStoreConnection $destSqlConn $destStore = New-Object Microsoft.SqlServer.Management.XEvent.XEStore $destSqlStoreConnection $storeSessions = $sourceStore.Sessions | Where-Object { $_.Name -notin 'AlwaysOn_health', 'system_health' } if ($XeSession) { $storeSessions = $storeSessions | Where-Object Name -In $XeSession } if ($ExcludeXeSession) { $storeSessions = $storeSessions | Where-Object Name -NotIn $ExcludeXeSession } Write-Message -Level Verbose -Message "Migrating sessions." foreach ($session in $storeSessions) { $sessionName = $session.Name $copyXeSessionStatus = [pscustomobject]@{ SourceServer = $sourceServer.Name DestinationServer = $destServer.Name Name = $sessionName Status = $null DateTime = [DbaDateTime](Get-Date) } if ($destStore.Sessions[$sessionName] -ne $null) { if ($force -eq $false) { $copyXeSessionStatus.Status = "Skipped" $copyXeSessionStatus Write-Message -Level Warning -Message "Extended Event Session '$sessionName' was skipped because it already exists on $destination."
