function Read-DbaAuditFile { <# .SYNOPSIS Read Audit details from *.sqlaudit files. .DESCRIPTION Read Audit details from *.sqlaudit files. .PARAMETER Path The path to the *.sqlaudit file. This is relative to the computer executing the command. UNC paths are supported. .PARAMETER Raw If this switch is enabled, the 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: XE, Audit, Security Author: Chrissy LeMaire (@cl), netnerds.net Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Read-DbaAuditFile .EXAMPLE PS C:\> Read-DbaAuditFile -Path C:\temp\logins.sqlaudit Returns events from C:\temp\logins.sqlaudit. .EXAMPLE PS C:\> Get-ChildItem C:\temp\audit\*.sqlaudit | Read-DbaAuditFile Returns events from all .sqlaudit files in C:\temp\audit. .EXAMPLE PS C:\> Get-DbaInstanceAudit -SqlInstance sql2014 -Audit LoginTracker | Read-DbaAuditFile Reads remote Audit details by accessing the file over the admin UNC share. #> [CmdletBinding()] param ( [parameter(Mandatory, ValueFromPipeline)] [Alias('FullName')] [object[]]$Path, [switch]$Raw, [switch]$EnableException ) process { foreach ($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 = $file } elseif ($file -is [System.IO.FileInfo]) { $currentFile = $file.FullName } else { if ($file -isnot [Microsoft.SqlServer.Management.Smo.Audit]) { Stop-Function -Message "Unsupported file type." return } if (-not $file.FullName) { Stop-Function -Message "This Audit does not have an associated file." return } $instance = [DbaInstanceParameter]$file.ComputerName if ($instance.IsLocalHost) { $currentFile = $file.FullName } else { $currentFile = $file.RemoteFullName } } $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).
