function Invoke-DbaCycleErrorLog { <# .SYNOPSIS Cycles the current instance or agent log. .DESCRIPTION Cycles the current error log for the instance (SQL Server) and/or SQL Server Agent. .PARAMETER SqlInstance The target SQL Server instance or instances.You must have sysadmin access and server version must be SQL Server version 2000 or higher. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Type The log to cycle. Accepts: instance or agent. .PARAMETER WhatIf If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run. .PARAMETER Confirm If this switch is enabled, you will be prompted for confirmation before executing any operations that change state. .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: Log, Cycle Author: Shawn Melton (@wsmelton), https://wsmelton.github.io Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Invoke-DbaCycleLog .EXAMPLE PS C:\> Invoke-DbaCycleLog -SqlInstance sql2016 -Type agent Cycles the current error log for the SQL Server Agent on SQL Server instance sql2016 .EXAMPLE PS C:\> Invoke-DbaCycleLog -SqlInstance sql2016 -Type instance Cycles the current error log for the SQL Server instance on SQL Server instance sql2016 .EXAMPLE PS C:\> Invoke-DbaCycleLog -SqlInstance sql2016 Cycles the current error log for both SQL Server instance and SQL Server Agent on SQL Server instance sql2016 #> [CmdletBinding(SupportsShouldProcess = $true, ConfirmImpact = 'Low')] param ( [parameter(Mandatory, ValueFromPipeline)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [Alias("Credential")] [PSCredential]$SqlCredential, [ValidateSet('instance', 'agent')] [string]$Type, [Alias('Silent')] [switch]$EnableException ) begin { if (Test-Bound 'Type') { if ($Type -notin 'instance', 'agent') { Stop-Function -Message "The type provided [$Type] for $SqlInstance is not an accepted value.
