Azure Metric Alert Rule - Unable to Split by Dimensions

Hi,

I am trying to create Alert rule on VMSS to monitor the Available memory bytes metric.

This metric allows to split the dimensions based on the VMname.

However, When I try to select the split by Dimensions option, the "Dimension Values" column keeps on loading. It is not allowing me to select any values. I have observed the same behavior for the HealthModel -Health Score Per Node metric as well. Can any one help with this issue?User's image

    @Vandita Misra - Welcome to Microsoft Q&A and thanks for reaching out to us and apologies for the delay in responding to you.

    It might be because the Azure portal is not able to retrieve the dimension values for the selected metric. This can happen if the metric data is not yet available or if there is an issue with the Azure portal.

    Please try the following steps and see if it helps:

    1. It is possible that the metric data is not yet available and needs some time to be collected.
    2. Check if the metric data is available in the Azure portal. Access Metrics Tab of your VMSS and select the Available memory bytes metric. If the metric data is not available, you might need to enable the metric collection for your VMSS.
    3. Try selecting a different dimension value. If the issue persists, you can try selecting a different dimension value for the metric. For example, you can try selecting the split by Instance d option instead of VMname.
    4. Use PowerShell or Azure CLI to create the alert rule. If the issue still persists, you can try creating the alert rule using PowerShell or Azure CLI. This will allow you to specify the dimension values directly in the command.

    Hope this helps. and please feel free to reach out if you have any further questions.
