Monitoring updates of our products (FTP Serv-u)

Dear all,

I would like new feature for check updates on FTP server. You have only message in management console but I would like to monitor it via Icinga or Nagios monitoring system.

I have installed FTP Serv-U on lot of windows servers.

I need same webservice or local script for check information about new updates. Get information about actual version, maybe priority of update and information about  end of date of support maintenance. 

Thank you

David Urban
