I’m currently running two diffrent Citrix farms, one on Presentation Server 4, and one on XenApp 6.5. Since I’m currently in the process of moving from one farm to another, I have to have very good control over how many servers I have in each farm, to always have enough resources on both farms. I really love qfarm /load and use it all the time, but I needed to automate it with our monitoring solution Nagios/Icinga. To do this, I’ve created the following powershellscript to monitor my farms, and get to know whenever there are missing resources.
