Hello,

Anyone has idea, why Azure Advisor has showing higher recommendation for VM.

Current_SKU Standard_F4s_v2
Recommended_SKU Standard_D4s_v3
Severity - High

We did not find any high cpu utilization nor there is any memory issues on the VM, still azure recommending high size but i believe it should recommend lower one !!

Any one knows the logic behind it ?134249-wrong-recommendation.png

    @Mohammed Sohel Thank you for reaching out with your query.

    The advanced evaluation model in Advisor considers shutting down virtual machines when all of these statements are true:

    • P95th of the maximum value of CPU utilization is less than 3%.
    • Network utilization is less than 2% over a seven-day period.
    • Memory pressure is lower than the threshold values

    Advisor considers resizing virtual machines when it's possible to fit the current load in a smaller SKU (within the same SKU family) or a smaller number of instances such that:

    • The current load doesn’t go above 80% utilization for workloads that aren't user facing.
    • The load doesn't go above 40% for user-facing workloads.

    If you haven't already , please go through this documentation on how to optimize virtual machine spend by resizing or shutting down underutilized instances.

    Post reviewing the above information if you have any further queries please let us know. Thanks
