#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# function Remove-DbaXESession { <# .SYNOPSIS Removes Extended Events sessions. .DESCRIPTION This script removes Extended Events sessions on a SQL Server instance. .PARAMETER SqlInstance Target SQL Server. You must have sysadmin access and server version must be SQL Server version 2008 or higher. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Session Specifies a list of Extended Events sessions to remove. .PARAMETER AllSessions If this switch is enabled, all Extended Events sessions will be removed except the packaged sessions AlwaysOn_health, system_health, telemetry_xevents. .PARAMETER InputObject Accepts a collection of XEsession objects as output by Get-DbaXESession. .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. .NOTES Tags: ExtendedEvent, XE, 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 .LINK https://dbatools.io/Remove-DbaXESession .EXAMPLE Remove-DbaXESession -SqlInstance sql2012 -AllSessions Removes all Extended Event Session on the sqlserver2014 instance. .EXAMPLE Remove-DbaXESession -SqlInstance sql2012 -Session xesession1,xesession2 Removes the xesession1 and xesession2 Extended Event sessions. .EXAMPLE Get-DbaXESession -SqlInstance sql2017 | Remove-DbaXESession -Confirm:$false Removes all sessions from sql2017, bypassing prompts. .EXAMPLE Get-DbaXESession -SqlInstance sql2012 -Session xesession1 | Remove-DbaXESession Removes the sessions returned from the Get-DbaXESession function. #> [CmdletBinding(DefaultParameterSetName = 'Session', SupportsShouldProcess, ConfirmImpact = 'High')] param ( [parameter(Position = 1, Mandatory, ParameterSetName = 'Session')] [parameter(Position = 1, Mandatory, ParameterSetName = 'All')] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [parameter(ParameterSetName = 'Session')] [parameter(ParameterSetName = 'All')] [PSCredential]$SqlCredential, [parameter(Mandatory, ParameterSetName = 'Session')] [Alias("Sessions")] [object[]]$Session, [parameter(Mandatory, ParameterSetName = 'All')] [switch]$AllSessions, [parameter(Mandatory, ValueFromPipeline, ParameterSetName = 'Object')] [Microsoft.SqlServer.Management.XEvent.Session[]]$InputObject, [switch]$EnableException ) begin { # Remove each XESession function Remove-XESessions { [CmdletBinding()] param ([Microsoft.SqlServer.Management.XEvent.Session[]]$xeSessions) foreach ($xe in $xeSessions) { $instance = $xe.Parent.Name $session = $xe.Name if ($Pscmdlet.ShouldProcess("$instance", "Removing XEvent Session $session")) { try { $xe.Drop() [pscustomobject]@{ ComputerName = $xe.Parent.ComputerName InstanceName = $xe.Parent.ServiceName SqlInstance = $xe.Parent.DomainInstanceName Session = $session Status = "Removed" } } catch { Stop-Function -Message "Could not remove XEvent Session on $instance" -Target $session -ErrorRecord $_ -Continue } } } } } process { if ($InputObject) { # avoid the collection issue $sessions = Get-DbaXESession -SqlInstance $InputObject.Parent -Session $InputObject.Name foreach ($item in $sessions) { Remove-XESessions $item } } else { foreach ($instance in $SqlInstance) { $xeSessions = Get-DbaXESession -SqlInstance $instance -SqlCredential $SqlCredential # Filter xeSessions based on parameters if ($Session) { $xeSessions = $xeSessions | Where-Object { $_.Name -in $Session } } elseif ($AllSessions) { $systemSessions = @('AlwaysOn_health', 'system_health', 'telemetry_xevents') $xeSessions = $xeSessions | Where-Object { $_.Name -notin $systemSessions } } Remove-XESessions $xeSessions } } } } |
