Azure Advisor – Reserved Instance & Right-Sizing Recommendations Not Visible

Question

We are unable to see Reserved Instance and Right-Sizing recommendations in Azure Advisor.

Is this a known issue or platform change affecting multiple tenants?

Hello Navinesh Nadar,

Thank you for reaching out to the Microsoft Q&A forum.

It sounds like you’re expecting to see both Reserved Instance (RI) purchase recommendations and Right-Sizing (under-utilized VM) recommendations in Azure Advisor, but those aren’t showing up. Here are the most common reasons and things to check:

You’re looking in the right place?

• Go to Azure Advisor > Cost tab for cost-optimization recommendations (RI and right-size live here).

• RI purchase recs also show up under the Reservations blade (click “Add” to see scoped billing-profile or billing-account recommendations).

Subscription type and permissions

• Cost recommendations are supported for Enterprise Agreement (EA) customers. If you’re on Pay-As-You-Go (MCA), CSP or another offer, RI recommendations still appear but rightsizing requires the Cost tab in Advisor.

• You need at least “Reader” on the subscription or resource group to view cost recs.

• Verify you haven’t scoped Advisor to an empty set of subscriptions via the portal’s global filter.

Sufficient usage data

• Right-Sizing (VM/VMSS) recs require at least 14 days of continuous VM activity.

• Reservation recs use a 30-day look-back. If you recently spun up VMs, wait until that window completes.

Advisor configuration filters

• Advisor lets you filter VM right-size recommendations by average CPU utilization. If someone set a high filter (say 80%), and your VMs run at 30–40%, Advisor may hide those suggestions.

• From any Advisor page click “Configuration” > “VM/VMSS right sizing” and confirm or lower the CPU threshold.

Shared-scope reservations vs. single-subscription

• Advisor only shows single-subscription scope recs under Cost. If you’re purchasing shared scope, go to Reservations > Add.

• After you buy a shared-scope RI, Advisor can take up to 5 days to remove the recommendation once it’s no longer needed.
