function Get-DbaServerTrigger {
    <#
        .SYNOPSIS
            Get all existing server triggers on one or more SQL instances.
 
        .DESCRIPTION
            Get all existing server triggers on one or more SQL instances.
 
        .PARAMETER SqlInstance
            The SQL Instance that you're connecting to.
 
        .PARAMETER SqlCredential
            SqlCredential object used to connect to the SQL Server as a different user.
 
        .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.
