function Copy-DbaXESession { <# .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 Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Destination Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2000 or higher. .PARAMETER DestinationSqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .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 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. .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 Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT Requires: sysadmin access on SQL Servers .LINK https://dbatools.io/Copy-DbaXESession .EXAMPLE PS C:\> Copy-DbaXESession -Source sqlserver2014a -Destination sqlcluster Copies all Extended Event sessions from sqlserver2014a to sqlcluster using Windows credentials. .EXAMPLE PS C:\> Copy-DbaXESession -Source sqlserver2014a -Destination sqlcluster -SourceSqlCredential $cred Copies all Extended Event sessions from sqlserver2014a to sqlcluster using SQL credentials for sqlserver2014a and Windows credentials for sqlcluster. .EXAMPLE PS C:\> Copy-DbaXESession -Source sqlserver2014a -Destination sqlcluster -WhatIf Shows what would happen if the command were executed. .EXAMPLE PS C:\> Copy-DbaXESession -Source sqlserver2014a -Destination sqlcluster -XeSession CheckQueries, MonitorUserDefinedException Copies only the Extended Events named CheckQueries and MonitorUserDefinedException from sqlserver2014a to sqlcluster. #> [CmdletBinding(DefaultParameterSetName = "Default", SupportsShouldProcess)] param ( [parameter(Mandatory)] [DbaInstanceParameter]$Source, [parameter(Mandatory)] [DbaInstanceParameter[]]$Destination, [PSCredential] $SourceSqlCredential, [PSCredential] $DestinationSqlCredential, [object[]]$XeSession, [object[]]$ExcludeXeSession, [switch]$Force, [Alias('Silent')] [switch]$EnableException ) begin { Test-DbaDeprecation -DeprecatedOn "1.0.0" -Alias Copy-DbaExtendedEvent try { $sourceServer = Connect-SqlInstance -SqlInstance $Source -SqlCredential $SourceSqlCredential -MinimumVersion 11 } catch { Stop-Function -Message "Failure" -Category ConnectionError -ErrorRecord $_ -Target $Source return } $sourceSqlConn = $sourceServer.ConnectionContext.SqlConnectionObject $sourceSqlStoreConnection = New-Object Microsoft.SqlServer.Management.Sdk.Sfc.SqlStoreConnection $sourceSqlConn $sourceStore = New-Object Microsoft.SqlServer.Management.XEvent.XEStore $sourceSqlStoreConnection $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 $ExcludeXeSession } } process { if (Test-FunctionInterrupt) { return } foreach ($destinstance in $Destination) { try { $destServer = Connect-SqlInstance -SqlInstance $destinstance -SqlCredential $DestinationSqlCredential -MinimumVersion 11 } catch { Stop-Function -Message "Failure" -Category ConnectionError -ErrorRecord $_ -Target $destinstance -Continue } $destSqlConn = $destServer.ConnectionContext.SqlConnectionObject $destSqlStoreConnection = New-Object Microsoft.SqlServer.Management.Sdk.Sfc.SqlStoreConnection $destSqlConn $destStore = New-Object Microsoft.SqlServer.Management.XEvent.XEStore $destSqlStoreConnection Write-Message -Level Verbose -Message "Migrating sessions." foreach ($session in $storeSessions) { $sessionName = $session.Name $copyXeSessionStatus = [pscustomobject]@{ SourceServer = $sourceServer.Name DestinationServer = $destServer.Name Name = $sessionName Type = "Extended Event" Status = $null Notes = $null DateTime = [DbaDateTime](Get-Date) } if ($null -ne $destStore.Sessions[$sessionName]) { if ($force -eq $false) { if ($Pscmdlet.ShouldProcess($destinstance, "Extended Event Session '$sessionName' was skipped because it already exists on $destinstance.")) { $copyXeSessionStatus.Status = "Skipped" $copyXeSessionStatus.Notes = "Already exists" $copyXeSessionStatus | Select-DefaultView -Property DateTime, SourceServer, DestinationServer, Name, Type, Status, Notes -TypeName MigrationObject Write-Message -Level Verbose -Message "Extended Event Session '$sessionName' was skipped because it already exists on $destinstance."
