Configure GPU monitoring with Container insights

Container insights supports monitoring GPU clusters from the following GPU vendors:

Container insights automatically starts monitoring GPU usage on nodes and GPU requesting pods and workloads by collecting the following metrics at 60-second intervals and storing them in the InsightMetrics table.

Note

After you provision clusters with GPU nodes, ensure that the GPU driver is installed as required by Azure Kubernetes Service (AKS) to run GPU workloads. Container insights collect GPU metrics through GPU driver pods running in the node.

Metric name Metric dimension (tags) Description
containerGpuDutyCycle* container.azm.ms/clusterId, container.azm.ms/clusterName, containerName, gpuId, gpuModel, gpuVendor Percentage of time over the past sample period (60 seconds) during which the GPU was busy/actively processing for a container. Duty cycle is a number between 1 and 100.
containerGpuLimits container.azm.ms/clusterId, container.azm.ms/clusterName, containerName Each container can specify limits as one or more GPUs. It isn't possible to request or limit a fraction of a GPU.
containerGpuRequests container.azm.ms/clusterId, container.azm.ms/clusterName, containerName Each container can request one or more GPUs. It isn't possible to request or limit a fraction of a GPU.
containerGpumemoryTotalBytes* container.azm.ms/clusterId, container.azm.ms/clusterName, containerName, gpuId, gpuModel, gpuVendor Amount of GPU memory in bytes available to use for a specific container.
containerGpumemoryUsedBytes* container.azm.ms/clusterId, container.azm.ms/clusterName, containerName, gpuId, gpuModel, gpuVendor Amount of GPU memory in bytes used by a specific container.
nodeGpuAllocatable container.azm.ms/clusterId, container.azm.ms/clusterName, gpuVendor Number of GPUs in a node that can be used by Kubernetes.
nodeGpuCapacity container.azm.ms/clusterId, container.azm.ms/clusterName, gpuVendor Total number of GPUs in a node.

* Based on Kubernetes upstream changes, these metrics are no longer collected out of the box. As a temporary hotfix, for AKS, upgrade your GPU node pool to the latest version or *-2022.06.08 or higher. For Azure Arc-enabled Kubernetes, enable the feature gate DisableAcceleratorUsageMetrics=false in kubelet configuration of the node and restart the kubelet. After the upstream changes reach general availability, this fix will no longer work.

GPU performance charts

Container insights includes preconfigured charts for the metrics listed earlier in the table as a GPU workbook for every cluster. For a description of the workbooks available for Container insights, see Workbooks in Container insights.
