Enable pod-based GPU metrics in Amazon CloudWatch | Amazon Web Services

In February 2022, Amazon Web Services added support for NVIDIA GPU metrics in Amazon CloudWatch, making it possible to push metrics from the Amazon CloudWatch and monitor your code for optimal GPU utilization. Since then, this feature has been integrated into many of our managed Amazon Machine Images (AMIs), such as the Deep Learning AMI and the AWS ParallelCluster AMI. To obtain instance-level metrics of GPU utilization, you can use Packer or the Amazon ImageBuilder to bootstrap your own custom AMI and use it in various managed service offerings like AWS Batch, Amazon Elastic Container Service (Amazon ECS), or Amazon Elastic Kubernetes Service (Amazon EKS). However, for many container-based service offerings and workloads, it’s ideal to capture utilization metrics on the container, pod, or namespace level.

This post details how to set up container-based GPU metrics and provides an example of collecting these metrics from EKS pods.

Solution overview

To demonstrate container-based GPU metrics, we create an EKS cluster with g5.2xlarge instances; however, this will work with any supported NVIDIA accelerated instance family.

We deploy the NVIDIA GPU operator to enable use of GPU resources and the NVIDIA DCGM Exporter to enable GPU metrics collection. Then we explore two architectures. The first one connects the metrics from NVIDIA DCGM Exporter to CloudWatch via a CloudWatch agent, as shown in the following diagram.

The second architecture (see the following diagram) connects the metrics from DCGM Exporter to Prometheus, then we use a Grafana dashboard to visualize those metrics.

Prerequisites

To simplify reproducing the entire stack from this post, we use a container that has all the required tooling (aws cli, eksctl, helm, etc.) already installed. In order to clone the AWS credentials. To enable access to Kubernetes services using port-forwarding, you will also need kubectl.

These prerequisites can be installed on your local machine, EC2 instance with NICE DCV, or AWS Cloud9. In this post, we will use a c5.2xlarge Cloud9 instance with a 40GB local storage volume. When using Cloud9, please disable AWS managed temporary credentials by visiting Cloud9->Preferences->AWS Settings as shown on the screenshot below.

Build and run the aws-do-eks container

Open a terminal shell in your preferred environment and run the following commands:

git clone https://github.com/aws-samples/aws-do-eks
cd aws-do-eks
./build.sh
./run.sh
./exec.sh

The result is as follows:

root@e5ecb162812f:/eks#

You now have a shell in a container environment that has all the tools needed to complete the tasks below. We will refer to it as “aws-do-eks shell”. You will be running the commands in the following sections in this shell, unless specifically instructed otherwise.

Create an EKS cluster with a node group

This group includes a GPU instance family of your choice; in this example, we use the g5.2xlarge instance type.

The aws-do-eks project comes with a collection of cluster configurations. You can set your desired cluster configuration with a single configuration change.

In the container shell, run ./env-config.sh and then set CONF=conf/eksctl/yaml/eks-gpu-g5.yaml
To verify the cluster configuration, run ./eks-config.sh

You should see the following cluster manifest:

apiVersion: eksctl.io/v1alpha5
kind: ClusterConfig
metadata: name: do-eks-yaml-g5 version: "1.25" region: us-east-1
availabilityZones: - us-east-1a - us-east-1b - us-east-1c - us-east-1d
managedNodeGroups: - name: sys instanceType: m5.xlarge desiredCapacity: 1 iam: withAddonPolicies: autoScaler: true cloudWatch: true - name: g5 instanceType: g5.2xlarge instancePrefix: g5-2xl privateNetworking: true efaEnabled: false minSize: 0 desiredCapacity: 1 maxSize: 10 volumeSize: 80 iam: withAddonPolicies: cloudWatch: true
iam: withOIDC: true

To create the cluster, run the following command in the container

./eks-create.sh

The output is as follows:

Done creating cluster using /eks/conf/eksctl/yaml/eks-gpu-g5.yaml /eks

To verify that your cluster is created successfully, run the following command

kubectl get nodes -L node.kubernetes.io/instance-type

The output is similar to the following:

NAME STATUS ROLES AGE VERSION INSTANCE_TYPE
ip-192-168-18-137.ec2.internal Ready <none> 47m v1.25.9-eks-0a21954 m5.xlarge
ip-192-168-214-241.ec2.internal Ready <none> 46m v1.25.9-eks-0a21954 g5.2xlarge

In this example, we have one m5.xlarge and one g5.2xlarge instance in our cluster; therefore, we see two nodes listed in the preceding output.

During the cluster creation process, the NVIDIA device plugin will get installed. You will need to remove it after cluster creation because we will use the NVIDIA GPU Operator instead.

Delete the plugin with the following command

kubectl -n kube-system delete daemonset nvidia-device-plugin-daemonset

We get the following output:

daemonset.apps "nvidia-device-plugin-daemonset" deleted

Install the NVIDIA Helm repo

Install the NVIDIA Helm repo with the following command:

helm repo add nvidia https://helm.ngc.nvidia.com/nvidia && helm repo update

Deploy the DCGM exporter with the NVIDIA GPU Operator

To deploy the DCGM exporter, complete the following steps:

Prepare the DCGM exporter GPU metrics configuration

curl https://raw.githubusercontent.com/NVIDIA/dcgm-exporter/main/etc/dcp-metrics-included.csv > dcgm-metrics.csv

You have the option to edit the dcgm-metrics.csv file. You can add or remove any metrics as needed.

Create the gpu-operator namespace and DCGM exporter ConfigMap

kubectl create namespace gpu-operator && /
kubectl create configmap metrics-config -n gpu-operator --from-file=dcgm-metrics.csv

The output is as follows:

namespace/gpu-operator created
configmap/metrics-config created

Apply the GPU operator to the EKS cluster

helm install --wait --generate-name -n gpu-operator --create-namespace nvidia/gpu-operator --set dcgmExporter.config.name=metrics-config --set dcgmExporter.env[0].name=DCGM_EXPORTER_COLLECTORS --set dcgmExporter.env[0].value=/etc/dcgm-exporter/dcgm-metrics.csv --set toolkit.enabled=false

The output is as follows:

NAME: gpu-operator-1684795140
LAST DEPLOYED: Day Month Date HH:mm:ss YYYY
NAMESPACE: gpu-operator
STATUS: deployed
REVISION: 1
TEST SUITE: None

Confirm that the DCGM exporter pod is running

kubectl -n gpu-operator get pods | grep dcgm

The output is as follows:

nvidia-dcgm-exporter-lkmfr       1/1     Running    0   1m

If you inspect the logs, you should see the “Starting webserver” message:

kubectl -n gpu-operator logs -f $(kubectl -n gpu-operator get pods | grep dcgm | cut -d ' ' -f 1)

The output is as follows:

NVIDIA DCGM Exporter exposes a Prometheus metrics endpoint, which can be ingested by the CloudWatch agent. To see the endpoint, use the following command:

kubectl -n gpu-operator get services | grep dcgm

We get the following output:

nvidia-dcgm-exporter    ClusterIP   10.100.183.207   <none>   9400/TCP   10m

To generate some GPU utilization, we deploy a pod that runs the gpu-burn binary

kubectl apply -f https://raw.githubusercontent.com/aws-samples/aws-do-eks/main/Container-Root/eks/deployment/gpu-metrics/gpu-burn-deployment.yaml

The output is as follows:

deployment.apps/gpu-burn created

This deployment uses a single GPU to produce a continuous pattern of 100% utilization for 20 seconds followed by 0% utilization for 20 seconds.

To make sure the endpoint works, you can run a temporary container that uses curl to read the content of http://nvidia-dcgm-exporter:9400/metrics

kubectl -n gpu-operator run -it --rm curl --restart='Never' --image=curlimages/curl --command -- curl http://nvidia-dcgm-exporter:9400/metrics

Configure and deploy the CloudWatch agent

To configure and deploy the CloudWatch agent, complete the following steps:

Download the YAML file and edit it

curl -O https://raw.githubusercontent.com/aws-samples/amazon-cloudwatch-container-insights/k8s/1.3.15/k8s-deployment-manifest-templates/deployment-mode/service/cwagent-prometheus/prometheus-eks.yaml

The file contains a cwagent configmap and a prometheus configmap. For this post, we edit both.

Edit the prometheus-eks.yaml file

Open the prometheus-eks.yaml file in your favorite editor and replace the cwagentconfig.json section with the following content:

apiVersion: v1
data: # cwagent json config cwagentconfig.json: | { "logs": { "metrics_collected": { "prometheus": { "prometheus_config_path": "/etc/prometheusconfig/prometheus.yaml", "emf_processor": { "metric_declaration": [ { "source_labels": ["Service"], "label_matcher": ".*dcgm.*", "dimensions": [["Service","Namespace","ClusterName","job","pod"]], "metric_selectors": [ "^DCGM_FI_DEV_GPU_UTIL$", "^DCGM_FI_DEV_DEC_UTIL$", "^DCGM_FI_DEV_ENC_UTIL$", "^DCGM_FI_DEV_MEM_CLOCK$", "^DCGM_FI_DEV_MEM_COPY_UTIL$", "^DCGM_FI_DEV_POWER_USAGE$", "^DCGM_FI_DEV_ROW_REMAP_FAILURE$", "^DCGM_FI_DEV_SM_CLOCK$", "^DCGM_FI_DEV_XID_ERRORS$", "^DCGM_FI_PROF_DRAM_ACTIVE$", "^DCGM_FI_PROF_GR_ENGINE_ACTIVE$", "^DCGM_FI_PROF_PCIE_RX_BYTES$", "^DCGM_FI_PROF_PCIE_TX_BYTES$", "^DCGM_FI_PROF_PIPE_TENSOR_ACTIVE$" ] } ] } } }, "force_flush_interval": 5 } }

In the prometheus config section, append the following job definition for the DCGM exporter

- job_name: 'kubernetes-pod-dcgm-exporter' sample_limit: 10000 metrics_path: /api/v1/metrics/prometheus kubernetes_sd_configs: - role: pod relabel_configs: - source_labels: [__meta_kubernetes_pod_container_name] action: keep regex: '^DCGM.*$' - source_labels: [__address__] action: replace regex: ([^:]+)(?::d+)? replacement: ${1}:9400 target_label: __address__ - action: labelmap regex: __meta_kubernetes_pod_label_(.+) - action: replace source_labels: - __meta_kubernetes_namespace target_label: Namespace - source_labels: [__meta_kubernetes_pod] action: replace target_label: pod - action: replace source_labels: - __meta_kubernetes_pod_container_name target_label: container_name - action: replace source_labels: - __meta_kubernetes_pod_controller_name target_label: pod_controller_name - action: replace source_labels: - __meta_kubernetes_pod_controller_kind target_label: pod_controller_kind - action: replace source_labels: - __meta_kubernetes_pod_phase target_label: pod_phase - action: replace source_labels: - __meta_kubernetes_pod_node_name target_label: NodeName

Save the file and apply the cwagent-dcgm configuration to your cluster

kubectl apply -f ./prometheus-eks.yaml

We get the following output:

namespace/amazon-cloudwatch created
configmap/prometheus-cwagentconfig created
configmap/prometheus-config created
serviceaccount/cwagent-prometheus created
clusterrole.rbac.authorization.k8s.io/cwagent-prometheus-role created
clusterrolebinding.rbac.authorization.k8s.io/cwagent-prometheus-role-binding created
deployment.apps/cwagent-prometheus created

Confirm that the CloudWatch agent pod is running

kubectl -n amazon-cloudwatch get pods

We get the following output:

NAME READY STATUS RESTARTS AGE
cwagent-prometheus-7dfd69cc46-s4cx7 1/1 Running 0 15m

Visualize metrics on the CloudWatch console

To visualize the metrics in CloudWatch, complete the following steps:

On the CloudWatch console, under Metrics in the navigation pane, choose All metrics
In the Custom namespaces section, choose the new entry for ContainerInsights/Prometheus

For more information about the ContainerInsights/Prometheus namespace, refer to Scraping additional Prometheus sources and importing those metrics.

CloudWatch - ContainerInsights/Prometeus

Drill down to the metric names and choose DCGM_FI_DEV_GPU_UTIL
On the Graphed metrics tab, set Period to 5 seconds

CloudWatch - Period Setting

Set the refresh interval to 10 seconds

You will see the metrics collected from DCGM exporter that visualize the gpu-burn pattern on and off each 20 seconds.

CloudWatch - gpuburn pattern

On the Browse tab, you can see the data, including the pod name for each metric.

CloudWatch - pod name for metric

The EKS API metadata has been combined with the DCGM metrics data, resulting in the provided pod-based GPU metrics.

This concludes the first approach of exporting DCGM metrics to CloudWatch via the CloudWatch agent.

In the next section, we configure the second architecture, which exports the DCGM metrics to Prometheus, and we visualize them with Grafana.

Use Prometheus and Grafana to visualize GPU metrics from DCGM

Complete the following steps:

Add the Prometheus community helm chart

helm repo add prometheus-community https://prometheus-community.github.io/helm-charts

This chart deploys both Prometheus and Grafana. We need to make some edits to the chart before running the install command.

Save the chart configuration values to a file in /tmp

helm inspect values prometheus-community/kube-prometheus-stack > /tmp/kube-prometheus-stack.values

Edit the char configuration file

Edit the saved file (/tmp/kube-prometheus-stack.values) and set the following option by looking for the setting name and setting the value:

prometheus.prometheusSpec.serviceMonitorSelectorNilUsesHelmValues=false

Add the following ConfigMap to the additionalScrapeConfigs section

additionalScrapeConfigs:
- job_name: gpu-metrics scrape_interval: 1s metrics_path: /metrics scheme: http kubernetes_sd_configs: - role: endpoints namespaces: names: - gpu-operator relabel_configs: - source_labels: [__meta_kubernetes_pod_node_name] action: replace target_label: kubernetes_node

Deploy the Prometheus stack with the updated values

helm install prometheus-community/kube-prometheus-stack 
--create-namespace --namespace prometheus 
--generate-name 
--values /tmp/kube-prometheus-stack.values

We get the following output:

NAME: kube-prometheus-stack-1684965548
LAST DEPLOYED: Wed May 24 21:59:14 2023
NAMESPACE: prometheus
STATUS: deployed
REVISION: 1
NOTES:
kube-prometheus-stack has been installed. Check its status by running: kubectl --namespace prometheus get pods -l "release=kube-prometheus-stack-1684965548" Visit https://github.com/prometheus-operator/kube-prometheus for instructions on how to create & configure Alertmanager and Prometheus instances using the Operator.

Confirm that the Prometheus pods are running

kubectl get pods -n prometheus

We get the following output:

NAME READY STATUS RESTARTS AGE
alertmanager-kube-prometheus-stack-1684-alertmanager-0 2/2 Running 0 6m55s
kube-prometheus-stack-1684-operator-6c87649878-j7v55 1/1 Running 0 6m58s

prometheus-kube-prometheus-stack-1684-prometheus-0 2/2 Running 0 6m55s

Prometheus and Grafana pods are in the Running state.

Next, we validate that DCGM metrics are flowing into Prometheus.

Port-forward the Prometheus UI

There are different ways to expose the Prometheus UI running in EKS to requests originating outside of the cluster. We will use kubectl port-forwarding. So far, we have been executing commands inside the aws-do-eks container. To access the Prometheus service running in the cluster, we will create a tunnel from the host. Here the aws-do-eks container is running by executing the following command outside of the container, in a new terminal shell on the host. We will refer to this as “host shell”.

kubectl -n prometheus port-forward svc/$(kubectl -n prometheus get svc | grep prometheus | grep -v alertmanager | grep -v operator | grep -v grafana | grep -v metrics | grep -v exporter | grep -v operated | cut -d ' ' -f 1) 8080:9090 &

While the port-forwarding process is running, we are able to access the Prometheus UI from the host as described below.

Open the Prometheus UI
- If you are using Cloud9, please navigate to Preview->Preview Running Application to open the Prometheus UI in a tab inside the Cloud9 IDE, then click the icon in the upper-right corner of the tab to pop out in a new window.
- If you are on your local host or connected to an EC2 instance via remote desktop open a browser and visit the URL http://localhost:8080.

Prometheus - DCGM metrics

Enter DCGM to see the DCGM metrics that are flowing into Prometheus
Select DCGM_FI_DEV_GPU_UTIL, choose Execute, and then navigate to the Graph tab to see the expected GPU utilization pattern

Prometheus - gpuburn pattern

Stop the Prometheus port-forwarding process

Run the following command line in your host shell:

kill -9 $(ps -aef | grep port-forward | grep -v grep | grep prometheus | awk '{print $2}')

Now we can visualize the DCGM metrics via Grafana Dashboard.

Retrieve the password to log in to the Grafana UI

kubectl -n prometheus get secret $(kubectl -n prometheus get secrets | grep grafana | cut -d ' ' -f 1) -o jsonpath="{.data.admin-password}" | base64 --decode ; echo

Port-forward the Grafana service

Run the following command line in your host shell:

kubectl port-forward -n prometheus svc/$(kubectl -n prometheus get svc | grep grafana | cut -d ' ' -f 1) 8080:80 &

Access the Grafana UI login screen the same way as you accessed the Prometheus UI earlier. If using Cloud9, select Preview->Preview Running Application, then pop out in a new window. If using your local host or an EC2 instance with remote desktop visit URL http://localhost:8080. Login with the user name admin and the password you retrieved earlier.

Grafana - login

In the navigation pane, choose Dashboards

Grafana - dashboards

Choose New and Import

Grafana - load by id from grafana.com
We are going to import the default DCGM Grafana dashboard described in NVIDIA DCGM Exporter Dashboard.

In the field import via grafana.com, enter 12239 and choose Load
Choose Prometheus as the data source
Choose Import

Grafana - import dashboard

You will see a dashboard similar to the one in the following screenshot.

Grafana - dashboard

To demonstrate that these metrics are pod-based, we are going to modify the GPU Utilization pane in this dashboard.

Choose the pane and the options menu (three dots)
Expand the Options section and edit the Legend field
Replace the value there with Pod {{pod}}, then choose Save

Grafana - pod-based metric
The legend now shows the gpu-burn pod name associated with the displayed GPU utilization.

Stop port-forwarding the Grafana UI service

Run the following in your host shell:

kill -9 $(ps -aef | grep port-forward | grep -v grep | grep prometheus | awk '{print $2}')

In this post, we demonstrated using open-source Prometheus and Grafana deployed to the EKS cluster. If desired, this deployment can be substituted with Amazon Managed Service for Prometheus and Amazon Managed Grafana.

Clean up

To clean up the resources you created, run the following script from the aws-do-eks container shell:

./eks-delete.sh

Conclusion

In this post, we utilized NVIDIA DCGM Exporter to collect GPU metrics and visualize them with either CloudWatch or Prometheus and Grafana. We invite you to use the architectures demonstrated here to enable GPU utilization monitoring with NVIDIA DCGM in your own AWS environment.
