The GPU Memory chart displays the amount of GPU memory used for the host in kilobytes and in percentage of the total available.

This chart is located in the Home view of the host Performance tab.
Note: The GPUs view is visible only if the host supports GPUs.

Chart Analysis

GPU Memory Usage (in Kilobytes) might not represent the active workload in the virtual machine, but the memory reserved for a virtual GPU.

Monitoring memory usage is essential to prevent out-of-memory errors, which can lead to application crashes or reduced performance.

If a virtual machine is experiencing a Quality of Service (QoS) issue, please refer to the GPU vendor QoS documentation. If you use NVIDIA virtual GPU (vGPU) technology, see the NVIDIA Virtual GPU Software for VMware vSphere documentation for more information.
