With multimedia requirements being more of a commodity for virtual desktop use cases, with previously being just a few users needing multimedia, hardware graphics acceleration is used for the complete virtual desktop estate. With that, we also need more insights into how the (virtual) GPUs are behaving. Standardly vROPS for Horizon does not give you insights into the GPU performance. The only GPU related performance metrics are for example in-guest (perfmon, GPU-z or GPU sizer), GPU hardware stats with nvidia-smi or looking at other desktop metrics (display protocol session details or compute resource usage). But with the release of the NVIDIA Virtual GPU Management Pack, we also have the option of getting these insights in vROPS for Horizon. This management pack will bring a new level of visibility into the health, performance, and efficiency of your virtual desktop estate with NVIDIA virtual GPU right down to the application level.
The NVIDIA Virtual GPU Management Pack supports all of NVIDIA’s virtual GPU products, including the Quadro Virtual Data Center Workstation (Quadro vDWS), the NVIDIA GRID Virtual PC (GRID vPC) and the NVIDIA GRID Virtual Apps (GRID vApps) products.
Let us see how we can make the vROPS for Horizon NVIDIA vGPU Management Pack work.
Using NVIDIA vGPU Management Pack
- vROPS for Horizon version – You will need vROPS for Horizon 6.5 that was released on last September. This makes it also possible to upgrade vROPS itself to 6.6. If you want some information about upgrading, see my previous post https://www.pascalswereld.nl/2017/09/26/vrops-upgrading-vrops-for-horizon-6-5-and-vrops-6-6/
- Grid Version – NVIDIA virtual GPU software version 5.0 or later driver package is configured on the hosts in your graphic accelerated ESXi compute cluster.
- NVIDIA Virtual GPU Management Pack – The NVIDIA GPU Management Pack downloaded and installed as a vROPS solution. Download here at the VMware Marketplace. With this, you will get the collecting adapter, NVIDIA dashboards, and GPU alert definitions.
- Connectivity vROPS to Hosts – vROPS for Horizon needs data flow to read the hardware GPU components at the host. CIM Secure server to CIM client (TCP 5989) connection from vROPS to the host is required here. If there is some filtering in between than nothing is showed in the dashboards while the solution will show green on collecting. In that case, you will need to open these ports.
To configure the NVIDIA Management Pack is easy if above requirements are met. After installing the NVIDIA Virtual GPU Management Pack for VMware vRealize Operations, you must configure it by creating an NVIDIA vGPU adapter instance. This is like configuring the vSphere Adapter, you will again need a connection to the vCenter that is managing your GPU enabled compute. It would be nice if we could re-use some of those adapters. When we fill in the vCenter FQDN and the credentials to be used from vROPS, we test the connection and save settings. And we have lift off. Give it some 10-15 minutes to have multiple cycles of the data collection (default is 5 minutes) before something is shown on the dashboards.
Getting those dashboards
The dashboards will give you GPU and host overview, encode and decode details, and memory utilization at the host or guest level. Or go even more in-depth with application-level monitoring capabilities. In the dashboard list, select on of the NVIDIA Dashboards.
Let us see what dashboards are shown here:
- NVIDIA Environment Overview – Showing an overview of the hardware state (temperature and alerts), and top GPU resource and en-/decoding utilization views
(some GPUs are a little high on temperature)
- NVIDIA Host Summary – Focus on the host details
- NVIDIA GPU Summary – Focus on the physical GPU details.
- NVIDIA vGPU Summary – Select on the vGPU of your environment and see properties details, relationships and other specifics for that vGPU
- NVIDIA Application Summary – Focus on a vGPU and the application process of those applications using the vGPU. Go in-depth of the utilization characteristics for that specific vGPU and process combination.
If you have vGPUs running in your Horizon virtual desktop estate, vROPS for Horizon with the NVIDIA vGPU management pack is a requirement to have an optimal centralized operational management solution. Not just on a one-to-one insight, but an overview of multiple virtual desktop vGPU insights.
– Enjoy having more NVIDIA GPU insights!
