We are moving towards using Citrix XenServer for new server deployments.  One of the issues with XenServer is that the free licenses needs to be re-activated every year.  Normally this is checked through the XenCenter system by going to Tools > License manager.  I have found that someone has made a Nagios plug-in to pull the license information and alert when the registration date is getting close.  If the system is not re-registered the VM's will not auto-start if the physical server is rebooted.  It's an annoyance but enough of one to find a solution.


Has anyone worked with XenServer and have a better, more automated way to check the license information?  It would be nice if Kaseya would be able to pull the information so that alerts could be set-up.
