You’re receiving this notice because you use Azure Red Hat OpenShift in the North Central US region.

We have identified high CPU utilization on the worker nodes of your Azure Red Hat OpenShift service in the North Central US region. To maintain optimal performance and avoid potential service disruptions, it is important to address this high resource usage. We recommend increasing the size of your worker virtual machines (VMs) or adding more worker nodes to your Azure Red Hat OpenShift environment.

Taking these actions will help ensure your workloads continue to run smoothly and efficiently.

Recommended Action

To avoid any service disruptions, scale your worker nodes by increasing the size of your worker VMs or adding more worker nodes as soon as possible.

Hello Rajesh Devarapally,

Thank you for contacting us about the issue. We have begun looking into it and will share our suggestions with you as soon as possible. If you have any additional details or concerns in the meantime, please let us know. We appreciate your patience while we work on this.

You received an alert about high CPU utilization on worker nodes in your Azure Red Hat OpenShift (ARO) cluster in the North Central US region. The alert references the subscription name but does not specify the cluster name.High CPU usage can occur due to:

Increased workload demand.

Insufficient node size or count.

Overloaded pods without autoscaling enabled.

Current worker node size and count.

Are autoscaling features enabled?

Any recent deployment changes?

We are working on this issue and will get back at the earliest.

Thanks,
Manish Deshpande

Rajesh Devarapally,

Thanks for reaching out. Regarding your query how to identity the cluster.

Please follow the below steps to verify the cluster name.

You can use the Azure CLI to list all ARO clusters that exist under the affected subscription. Run the following command:

az aro list --subscription "<subscription-id>" -o table

This will display all ARO clusters created in that subscription, along with their regions. From the output, check for the cluster deployed in the North Central US region — that’s the one likely referenced in the alert.

Check Azure Service Health Alert Details:

Navigate to the Azure Portal >> Service Health >> Health Alerts.

Locate the alert titled similarly to "High CPU utilization detected on Azure Red Hat OpenShift worker nodes in North Central US".

Expand the Impacted Resources section within the alert to view the exact cluster name and related resource details.

This approach will help you accurately identify which cluster is experiencing the reported high CPU utilization.

For your reference, here are related Microsoft documentation links to assist you:

View and manage Azure Service Health alerts

If you have already tried the above steps and are facing difficulties in identifying the cluster name or require further assistance, please let me know.

Hi @Anonymous Thanks for the inputs, i was able to locate the alert in UI, however i still do not cluster name, same with cli as well. please find the details and see if you can help.

there were bunch of clusters listed in cli but its hard to identify the cluster which has impacted.

az aro list --subscription "HCSC Azure Dev - Infrastructure" -o table

Answer 1

Hello @Rajesh Devarapally

Apologies for the delayed response could you please try this steps and help us with some details we have pinged you over the Private message.

In Azure Portal, go to: Service Health → Health Alerts → Select the alert (High CPU utilization).
Expand Impacted Resources. This section should list the Resource ID or ARO cluster name. If the cluster name is not visible, copy the Resource ID.

Use Azure CLI to filter clusters by Resource ID

  az resource show --ids <Resource-ID> --query "{name:name, resourceGroup:resourceGroup}"

This will return the cluster name and resource group.

From your CLI output, all clusters are in northcentralus. If Resource ID is not available, check the alert details for any tags or resource group hints.

Compare with your CLI list:
arod03 hcsc_APP00046878_dev_nc_rg
arod02 hcsc_app00046878_dev_nc_das_rg
arod05 hcsc_APP00046878_dev_nc_rg
arod08 hcsc_APP00046878_dev_nc_rg
arod01 hcsc_APP00046878_dev_nc_rg

Log in to the cluster console (URL from CLI output).
Navigate to Compute → Nodes.
Check CPU utilization per node.

Scale Up Worker Nodes

  az aro update --name <cluster-name> --resource-group <resource-group> --worker-vm-size Standard_D8s_v3

Add More Worker Nodes

  az aro update --name <cluster-name> --resource-group <resource-group> --worker-count <new-count>

Ensure autoscaling is enabled for workloads if applicable.

ARO Console → Monitoring → Metrics

  az monitor metrics list --resource <Resource-ID> --metric "CPUUsage"
