function Remove-DbaAgentAlertCategory { <# .SYNOPSIS Remove-DbaAgentAlertCategory removes an alert category. .DESCRIPTION Remove-DbaAgentAlertCategory makes it possible to remove an alert category. Insure that the category you want to remove is not used with any alerts. If an alert uses this category it will be get the category [Uncategorized]. .PARAMETER SqlInstance The target SQL Server instance or instances. You must have sysadmin access and server version must be SQL Server version 2000 or greater. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential). Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported. For MFA support, please use Connect-DbaInstance. .PARAMETER Category The name of the category .PARAMETER Force The force parameter will ignore some errors in the parameters and assume defaults. .PARAMETER WhatIf Shows what would happen if the command were to run. No actions are actually performed. .PARAMETER Confirm Prompts you for confirmation before executing any changing operations within the command. .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: Agent, Alert, AlertCategory Author: Patrick Flynn (@sqllensman) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Remove-DbaAgentAlertCategory .EXAMPLE PS C:\> Remove-DbaAgentAlertCategory -SqlInstance sql1 -Category 'Category 1' Remove the alert category Category 1 from the instance. .EXAMPLE PS C:\> Remove-DbaAgentAlertCategory -SqlInstance sql1 -Category Category1, Category2, Category3 Remove multiple alert categories from the instance. .EXAMPLE PS C:\> Remove-DbaAgentAlertCategory -SqlInstance sql1, sql2, sql3 -Category Category1, Category2, Category3 Remove multiple alert categories from the multiple instances. #> [CmdletBinding(SupportsShouldProcess, ConfirmImpact = "Low")] param ( [parameter(Mandatory, ValueFromPipeline)] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [ValidateNotNullOrEmpty()] [string[]]$Category, [switch]$Force, [switch]$EnableException ) begin { if ($Force) { $ConfirmPreference = 'none' } } process { foreach ($instance in $SqlInstance) { try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential } catch { Stop-Function -Message "Error occurred while establishing connection to $instance" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } foreach ($cat in $Category) { if ($cat -notin $server.JobServer.AlertCategories.Name) { Stop-Function -Message "Alert category $cat doesn't exist on $instance" -Target $instance -Continue } if ($PSCmdlet.ShouldProcess($instance, "Removing the alert category $Category")) { try { $currentCategory = $server.JobServer.AlertCategories[$cat] Write-Message -Message "Removing alert category $cat" -Level Verbose $currentCategory.Drop() } catch { Stop-Function -Message "Something went wrong removing the alert category $cat on $instance" -Target $cat -Continue -ErrorRecord $_ } } } } } } |
