Does PRTG impair my Citrix environment?



Since I have been monitoring my Citrix XenApp servers with PRTG, the connection between the XenApp Delivery Controller and the terminal servers always drops as soon as monitoring is active.

Is this an issue of PRTG? How can I monitor Citrix XenApp servers with PRTG without any impairments?

Monitoring Citrix XenApp servers without disconnects

PRTG does not directly cause problems in Citrix environments. The disconnects of XenApp terminal servers are the result of an error in the Citrix service that appears after the logoff of an RDP session.

In this case, the affected server changes to the status unregistered for a few seconds. If you monitor the server with the RDP (Remote Desktop) sensor, this status change happens with every sensor scan.

You can resolve this issue with the Citrix private hotfix LC0251 that is specific to these RDP session disconnects. Apply this fix to your Citrix XenApp servers and the problem will not appear anymore if you monitor the Citrix environment with the RDP (Remote Desktop) sensor.
