Koukaam NETIO power outlets offer a network interface that can be used for controlling the particular ports comfortably. It would be even nicer to monitor them with Nagios or Icinga. 2012 I created a provisional bash script for monitoring the ports and time synchronization over NTP.
This weekend I migrated the script to Python and also implemented new features.
The script that can be downloaded at no cost on Icinga Exchange is now also capable of monitoring particular ports.
Details about installation and configuration and a RPM specfile are part of the documentation.
