#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# function Stop-DbaXESession { <# .SYNOPSIS Stops Extended Events sessions. .DESCRIPTION This script stops Extended Events sessions on a SQL Server instance. .PARAMETER SqlInstance The target SQL Server instance or instances. 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 individual Extended Events sessions to stop. .PARAMETER AllSessions If this switch is enabled, all Extended Events sessions will be stopped except the packaged sessions AlwaysOn_health, system_health, telemetry_xevents. .PARAMETER InputObject Accepts the object output by Get-DbaXESession as the list of sessions to be stopped. .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: Doug Meyers Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Stop-DbaXESession .EXAMPLE PS C:\> Stop-DbaXESession -SqlInstance sqlserver2012 -AllSessions Stops all Extended Event Session on the sqlserver2014 instance. .EXAMPLE PS C:\> Stop-DbaXESession -SqlInstance sqlserver2012 -Session xesession1,xesession2 Stops the xesession1 and xesession2 Extended Event sessions. .EXAMPLE PS C:\> Get-DbaXESession -SqlInstance sqlserver2012 -Session xesession1 | Stop-DbaXESession Stops the sessions returned from the Get-DbaXESession function. #> [CmdletBinding(DefaultParameterSetName = 'Session')] 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 { # Stop each XESession function Stop-XESessions { [CmdletBinding()] param ([Microsoft.SqlServer.Management.XEvent.Session[]]$xeSessions) foreach ($xe in $xeSessions) { $instance = $xe.Parent.Name $session = $xe.Name if ($xe.isRunning) { Write-Message -Level Verbose -Message "Stopping XEvent Session $session on $instance." try { $xe.Stop() } catch { Stop-Function -Message "Could not stop XEvent Session on $instance" -Target $session -ErrorRecord $_ -Continue } } else { Write-Message -Level Warning -Message "$session on $instance is already stopped" } Get-DbaXESession -SqlInstance $xe.Parent -Session $session } } } process { if ($InputObject) { Stop-XESessions $InputObject } else { foreach ($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 } } Stop-XESessions $xeSessions } } } } |
