A user asked about getting Frames Per Second metrics from Citrix sessions in ControlUp. It was suggested that the user posts a User Voice item with the details of the request. After the user shared their connection to Citrix engineering, new metric data will be integrated into ControlUp version 9.1.

Performance Monitor Counters – An Overview
@member shared insight into various Performance Monitor Counters, such as CPU Queue Length, Disk Queue Length, Open Handles, Context Switches, and Peak User Input Delay. These metrics measure capacity, thread waiting to be executed, open file handles, rate of context switches, and maximum delay experienced by user input, respectively. Information on these metrics can be found in Microsoft documents (https://systemcenter.wiki/) and a blog post by ControlUp (https://www.controlup.com/resources/blog/).

Reducing Login Times with ControlUp
A discussion was had on reducing login times using Citrix Profile Management, group policies and folder redirection. AppX Load Packages and App/Desktop Icon clicked until ICA File Downloaded are taking up significant time. Server OS machines have faster AppX package loads than Client OS machines, indicating the possibility of using Server VDI. More information can be found in the ControlUp blog post at https://www.controlup.com/resources/blog/entry/logon-duration-research-appx-packages/.

Troubleshooting a Telephony Issue With ControlUp Data
A user asked if it is possible to get granular data from ControlUp to troubleshoot an issue with calls dropping on a telephony system. It was suggested that an alert or script be set up to gather data, however the customer preferred to use Citrix ADM. ControlUp already gives extra details for the Protocol Latency metric such as Min, Max and Avg over a 5-minute interval and users were asked if this was helpful for the issue. The question was left open-ended to determine if more granular data could be made available in the future.

Troubleshooting Video Latency on Non-Persistent VM with ControlUp
A user asked about troubleshooting video latency on a non-persistent VM, and it was suggested to use User Session Details in Solve as the best starting point. If Remote DX was installed, they can also watch session relevant latency, CPU, RAM and other metrics in a single place. Script Action can be used for advanced data collection. The Network Latency graph may be legit, but there was a known issue with the Linux RDX plugin. A new beta version which fixes this issue will be available soon. After sifting through the data, 3.75GB of RAM usage was found - they will look at adjusting graphics settings with Horizon View.

Understanding Bandwidth Limit and How it Differs from Speed Test in ControlUp
The discussion covered understanding bandwidth Limit, what it is related to, and how it differs from Speed Test. It was suggested RemoteDX or Edge can be used to run periodic bandwidth tests and determine the type of tests to run. It was also suggested that bandwidth limit is stored historically and that what factors need to be considered when measuring latency and disconnections.

How to fix this false positive in ControlUp?
User asked for help with false positive - 400s for Windows Shell, caused by loopback processing mode and RSoP logging not being configured.

Does the Bandwidth Limit metric come from the Citrix EDT logic?
A question was asked about the Bandwidth Limit metric from the Citrix EDT logic - this is estimated by sending two packets of known size and measuring the time it takes to transmit them. The metric is measured in Mbps and it should not be lower than 1 or 2 Mbps as Citrix is nimble in its bandwidth consumption. Thanks to @member for clarifying.

After upgrading Citrix VDA to 2203CU2 have noticed the HDX Latency to be erroneous and erratic?
Users reported incorrect HDX Latency and Round Trip Time (RTT) values in Citrix VDA versions 2112 and earlier. The issue can be fixed by disabling the HDX Adaptive Scaling feature in the VDA registry (CVADHELP-19781). Changing the CU setting to current value and disabling Remote DX latency may also help. More information can be found in the Citrix documentation at https://docs.citrix.com/en-us/citrix-virtual-apps-desktops/2203-ltsr/whats-new/cumulative-update-1/fixed-issues.html.

Error “This app can’t run on your PC” trying to use Remote Assistance on the ControlUp Console
When attempting to use Remote Assistance from the console, a file with no association appears. It is not possible to use the console on Server machines. Enabling the desktop experience feature may help. There is also a scripted action called "Shadow session" to enable it properly, however group policy values and administrator access to the target machine may be required. More information can be found at https://www.controlup.com/script-library-posts/shadow-session/.
