function Remove-DbaXESession { <# .SYNOPSIS Removes Extended Events sessions. .DESCRIPTION This script starts Extended Events sessions on a SQL Server instance. .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 Session Only remove specific Extended Events sessions. .PARAMETER AllSessions Remove all Extended Events sessions on an instance, ignoring the packaged sessions: AlwaysOn_health, system_health, telemetry_xevents. .PARAMETER InputObject Internal parameter to support piping from Get-DbaXESession .PARAMETER WhatIf Shows what would happen if the command were to run. No actions are actually performed. .PARAMETER Confirm Prompts you for confirmation before executing any changing operations within the command. .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: Xevent 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/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:$false Removes all sessions from sql2017, bypassing prompting .EXAMPLE Get-DbaXESession -SqlInstance sql2012 -Session xesession1 | Remove-DbaXESession Removes the sessions returned from the Get-DbaXESession function. #> [CmdletBinding(DefaultParameterSetName = 'Session', SupportsShouldProcess, ConfirmImpact = 'High')] param ( [parameter(Position = 1, Mandatory, ParameterSetName = 'Session')] [parameter(Position = 1, Mandatory, ParameterSetName = 'All')] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$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.NetName InstanceName = $xe.Parent.ServiceName SqlInstance = $xe.Parent.DomainInstanceName Session = $session Status = "Successful" } } 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 } } } } |
