A discussion took place about vGPU metrics and how they differ depending on whether Windows or Nvidia API is used for data collection. One member asked for tips on making data collection via Nvidia API work and another member suggested checking for the installation of NVIDIA WMI and restarting the ControlUp agent after switching. ControlUp documentation on vGPU can be found at https://support.controlup.com/v1/docs/gpu-monitoring-with-controlup#collecting-data-from-nvidia-api-optional.

Troubleshooting High Peak User Input Delays in ControlUp
A user asked for recommendations to diagnose high Peak User Input Delays. Another user suggested zooming in on the time of the delay and checking memory usage. They also shared how to find information on what application is slow to respond to user input. The discussion then focused on how to identify the cause of a slow application, often due to resource constraints. The team provided examples, such as MMCexe processing event logs, and suggested that more resources may not always solve the issue.

Investigating Performance Issues in Citrix VDI with NVIDIA GRID GPU
A user reported strange performance differences between identical Citrix VDI machines with NVIDIA GRID GPU configured, all started from the same master. Though NVIDIA licensing and configuration was OK, some machines did not show a GPU in use. Other users suggested checking the ControlUp Agent delayed start setting and switching between native Microsoft APIs and NVIDIA metrics (https://support.controlup.com/docs/gpu-monitoring-with-controlup?highlight=gpu). They also recommended looking at known issues. The customer planned to investigate the issue further the next day.

Feature Requests to Expand ControlUp Reporting Capabilities
A user asked that ControlUp allow for Historic Data for GPU and Datastore latency and I/O historically in Reports via UserVoice suggestions, and urged others to upvote. ControlUp revealed they have already implemented Historic Data for GPU in some environments, and do not find granular Datastore data for latency and I/O useful since they don't look deeper than average/max over 5 minutes.

Does ControlUp Use WMI APIs?
The discussion provided an audit answer to the question of if the WMI APIs are used to manage virtual network resources. ControlUp usually uses them sparingly, such as for GPU data collection, but not for Monitor. A Script Action at https://www.controlup.com/script-library-posts/show-local-wmi-activity/ can be used to trace which process uses which WMI query.

Troubleshooting High GPU Memory Usage: How to Show GPU Memory Usage by Process?
A user noticed high GPU memory usage for VDI (80 to 95%) in the COP Console but when they selected processes, the GPU Utilization, Decoder Utilization, Encoder Utilization, and Frame Buffer Memory Utilization all showed 0%. They were wondering if there was a way to show the GPU memory usage by process. Another user suggested selecting System Sessiosn from the dropdown, but this was already done. It was suggested to check the GPU Utilization for more usage to narrow down the issue, but further investigation was needed.

Investigating Unreachable ControlUp Agent VMs
This user asked for advice on the issue of VM's becoming unreachable due to Horizon Agent issues, experiencing freezing applications and an inability to console or access the machine once it has reached this state. Causes such as port exhaustion and DNS issues were discussed, as well as suggestions on how to access the system and application log files, and to generate an OS crash dump. It was also suggested to review reassess the configuration and consult other Horizon tech communities. ControlUp historical data and the support article https://support.controlup.com/ docs/controlup-agent-temporary-mode-and-how-to-change-it?highlight=IsTemporary#what-is-the-fix-for-this-problem were also included.

Storage Trends in ControlUp
A user asked for trends regarding storage in ControlUp. It is possible to view IO stats, though missing capacity information is not available yet. However, ControlUp will add trends as reference for the statistics reports in the Streaming project, including capacity and free space information. There will also be Disk entity reports with relevant information and recommendations. A session can be coordinated to discuss the plan.
