For us XenApp 6.5 upgraders (Since Citrix is forcing us)

RM where are you now in days?

I am now looking into a free utility called Farm Nanny written by Michel Stevelmans.

Although Citrix EdgeSight is completely packed with features, it is a little top-heavy and personally I still miss the good old Citrix resource manager because it was a quick and easy way to get an overview of what’s going on with your farm and servers.
Sure there are a lot of PowerShell scripts to be found which give you an overview of your farm, but those scripts are just snap-shots of your environment.
What you really need is something that monitors your Citrix XenApp farm in real-time

Farm Nanny is a Citrix XenApp farm monitoring application for XenApp 6 and XenApp 6.5 which will help you with troubleshooting, health checks and resource monitoring.

The following features are currently included:

• Citrix XenApp farm servers & status
• Session counter
• Load by server
• Active ICA sessions by server
• Active ICA sessions by farm
• Disconnected ICA sessions by server
• Disconnected ICA sessions by farm
• Logons enabled / disabled by server
• Load evaluator by server
• Zone by server
• Worker Group by server
• Sortable column view
• IP addresses by server
• Available memory by server
• Available diskspace by server
• Server uptime

.NET Framework 3.5 is required, but if you are running XenApp 6 or XenApp 6.5, you are also running Windows 2008 R2 which comes the correct .NET Framework by default.
