    <#

    .SYNOPSIS

        New-DbaAgentAlertCategory creates a new alert category.

    .DESCRIPTION

        New-DbaAgentAlertCategory makes it possible to create a Agent Alert category that can be used with Alerts.

        It returns an array of the alert categories created .

    .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.
