#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# function Get-DbaXESession { <# .SYNOPSIS Gets a list of Extended Events Sessions from the specified SQL Server instance(s). .DESCRIPTION Retrieves a list of Extended Events Sessions present on the specified SQL Server instance(s). .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 Only return specific sessions. Options for this parameter are auto-populated from the server. .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: Klaas Vandenberghe (@PowerDBAKlaas) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaXESession .EXAMPLE PS C:\> Get-DbaXESession -SqlInstance ServerA\sql987 Returns a custom object with ComputerName, SQLInstance, Session, StartTime, Status and other properties. .EXAMPLE PS C:\> Get-DbaXESession -SqlInstance ServerA\sql987 | Format-Table ComputerName, SqlInstance, Session, Status -AutoSize Returns a formatted table displaying ComputerName, SqlInstance, Session, and Status. .EXAMPLE PS C:\> 'ServerA\sql987','ServerB' | Get-DbaXESession Returns a custom object with ComputerName, SqlInstance, Session, StartTime, Status and other properties, from multiple SQL instances. #> [CmdletBinding()] param ( [parameter(Mandatory, ValueFromPipeline)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [Alias("Sessions")] [object[]]$Session, [Alias('Silent')] [switch]$EnableException ) begin { Test-DbaDeprecation -DeprecatedOn "1.0.0" -EnableException:$false -Alias Get-DbaXEsSession } process { foreach ($instance in $SqlInstance) { try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential -MinimumVersion 11 -AzureUnsupported $SqlConn = $server.ConnectionContext.SqlConnectionObject $SqlStoreConnection = New-Object Microsoft.SqlServer.Management.Sdk.Sfc.SqlStoreConnection $SqlConn $XEStore = New-Object Microsoft.SqlServer.Management.XEvent.XEStore $SqlStoreConnection } catch { Stop-Function -Message "Failure" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } Write-Message -Level Verbose -Message "Getting XEvents Sessions on $instance." $xesessions = $XEStore.sessions if ($Session) { $xesessions = $xesessions | Where-Object { $_.Name -in $Session } } foreach ($x in $xesessions) { $status = switch ($x.IsRunning) { $true { "Running" } $false { "Stopped" } } $files = $x.Targets.TargetFields | Where-Object Name -eq Filename | Select-Object -ExpandProperty Value $filecollection = $remotefile = @() if ($files) { foreach ($file in $files) { if ($file -notmatch ':\\' -and $file -notmatch '\\\\') { $directory = $server.ErrorLogPath.TrimEnd("\") $file = "$directory\$file" } $filecollection += $file $remotefile += Join-AdminUnc -servername $server.ComputerName -filepath $file } } Add-Member -Force -InputObject $x -MemberType NoteProperty -Name ComputerName -Value $server.ComputerName Add-Member -Force -InputObject $x -MemberType NoteProperty -Name InstanceName -Value $server.ServiceName Add-Member -Force -InputObject $x -MemberType NoteProperty -Name SqlInstance -Value $server.DomainInstanceName Add-Member -Force -InputObject $x -MemberType NoteProperty -Name Status -Value $status Add-Member -Force -InputObject $x -MemberType NoteProperty -Name Session -Value $x.Name Add-Member -Force -InputObject $x -MemberType NoteProperty -Name TargetFile -Value $filecollection Add-Member -Force -InputObject $x -MemberType NoteProperty -Name RemoteTargetFile -Value $remotefile Add-Member -Force -InputObject $x -MemberType NoteProperty -Name Parent -Value $server Add-Member -Force -InputObject $x -MemberType NoteProperty -Name Store -Value $XEStore Select-DefaultView -InputObject $x -Property ComputerName, InstanceName, SqlInstance, Name, Status, StartTime, AutoStart, State, Targets, TargetFile, Events, MaxMemory, MaxEventSize } } } } |
