#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# 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 xel or xem file. This is relative to the computer executing the command. UNC paths are supported. .PARAMETER Exact If this switch is enabled, only an exact search will be used for the Path. By default, this command will add a wildcard to the Path because Eventing uses the file name as a template and adds characters. .PARAMETER Raw If this switch is enabled, the Microsoft.SqlServer.XEvent.Linq.PublishedEvent enumeration object will be returned. .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) Chrissy LeMaire, clemaire@gmail.com License: MIT https://opensource.org/licenses/MIT .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 accessing 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) { # in order to ensure CSV gets all fields, all columns will be # collected and output in the first (all all subsequent) object $columns = @("name", "timestamp") if ($file -is [System.String]) { $currentfile = $file $manualadd = $true } elseif ($file -is [System.IO.FileInfo]) { $currentfile = $file.FullName $manualadd = $true } else { if ($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 = $currentfile.Replace('.xem', '*.xem') if ($currentfile -notmatch "xel" -and $currentfile -notmatch "xem") { $currentfile = "$currentfile*.xel" } } $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).
