It is the Citrix team’s responsibility to check the Citrix license server usage and report to the usage. We do not have license usage monitoring and notification directly in all the Citrix versions. Citrix Director shows the information but we have to login to the Director portal to see this alert. It is also available in Citrix Cloud. But in some environments, the Citrix team may not login to the Director portal every day. So, how do they get notified on peak license usage?
I have encountered the same problem and came up with a script. With this script, you don’t have to monitor licenses every day. It automatically emails you when the licenses are less than 10%. You can change these values as per your environment.
