function Read-DbaXEFile { <# .SYNOPSIS Read XEvents from a xel or xem file .DESCRIPTION Read XEvents from a xel or xem file. .PARAMETER Path The path to the file. This is relative to the computer executing the command. UNC paths supported. .PARAMETER Exact By default, this command will add a wildcard to the Path because Eventing uses the file name as a template and adds characters. Use this to skip the addition of the wildcard. .PARAMETER Raw Returns the Microsoft.SqlServer.XEvent.Linq.PublishedEvent enumeration object .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/Read-DbaXEFile .EXAMPLE Read-DbaXEFile -Path C:\temp\deadocks.xel Returns events from C:\temp\deadocks.xel .EXAMPLE Get-ChildItem C:\temp\xe\*.xel | Read-DbaXEFile Returns events from all .xel files in C:\temp\xe .EXAMPLE Get-DbaXESession -SqlInstance sql2014 -Session deadlocks | Read-DbaXEFile Reads remote xevents by acccessing the file over the admin UNC share #> [CmdletBinding()] param ( [parameter(Mandatory, ValueFromPipeline)] [Alias('FullName')] [object[]]$Path, [switch]$Exact, [switch]$Raw, [switch][Alias('Silent')] $EnableException ) process { foreach ($file in $path) { if ($file -is [System.String]) { $currentfile = $file } elseif ($file -is [System.IO.FileInfo]) { $currentfile = $file.FullName } else { if ($file -isnot [Microsoft.SqlServer.Management.XEvent.Session]) { Stop-Function -Message "Unsupported file type" return } if ($file.TargetFile.Length -eq 0) { Stop-Function -Message "This session does not have an associated Target File" return } $instance = [dbainstance]$file.ComputerName if ($instance.IsLocalHost) { $currentfile = $file.TargetFile } else { $currentfile = $file.RemoteTargetFile } } if (-not $Exact) { $currentfile = $currentfile.Replace('.xel', '*.xel') $currentfile = $currentfile.Replace('.xem', '*.xem') } $accessible = Test-Path -Path $currentfile $whoami = whoami if (-not $accessible) { if ($file.Status -eq "Stopped") { continue } Stop-Function -Continue -Message "$currentfile cannot be accessed from $($env:COMPUTERNAME).
