function Find-DbaDatabaseGrowthEvent {
    <#
  .SYNOPSIS
   Finds any database AutoGrow events in the Default Trace.
 
  .DESCRIPTION
   Finds any database AutoGrow events in the Default Trace.
 
  .PARAMETER SqlInstance
   The SQL Server that you're connecting to.
 
  .PARAMETER SqlCredential
   SqlCredential object used to connect to the SQL Server as a different user.
 
  .PARAMETER Database
   The database(s) to process - this list is auto-populated from the server. If unspecified, all databases will be processed.
 
  .PARAMETER ExcludeDatabase
   The database(s) to exclude - this list is auto-populated from the server
 
  .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.

   Returns any database AutoGrow events in the Default Traces for every database on ServerA\sql2016 & ServerA\SQL2014.
 
  .EXAMPLE
   Find-DBADatabaseGrowthEvent -SqlInstance ServerA\SQL2016 | Format-Table -AutoSize -Wrap
