# Virtual Machines. Right-sizing – VMs Undersized for Memory and CPU (OpsMgr agent data)

This report helps you detect virtual machines that have less allocated vRAM or vCPU resources than they require. The report will only support VMs that run OpsMgr agents inside the virtualized OS (for VMs without agents, use the [Undersized VMs report](vms_rightsizing_undersized.md) that was present in previous releases).

The report analyzes historical data on *% Memory Used* and *% Processor Time* performance metric values collected by the OpsMgr agent running in the guest OS. These metrics gathered inside the guest OS provide better recommendations for right-sizing (especially in terms of memory usage).

## Example Output

In this example, the report allows you to detect top 10 VMs that have less allocated memory than they require. Performance statistics for the last month were used as a basis for the report analysis.

To run this report:

1. From the **From** list, select *This month > First day*. From the **To** list, select *Today*.
2. From the **Sections to Show** list, select *vRAM*.
3. From the **Show Details** list, select *Yes (expanded)*.
4. From the **Performance Modeling Based On** list, select *Average Usage*.
5. Leave the **Scope** section without changes.
6. In the **Top N Count** field, enter *10*.
7. Click **Run** to view the report.

The report will show tables and charts displaying information on top 10 VMs memory consumption: allocated, recommended, min/max and average memory values, standard deviation and current configuration.

::: note

All recommendations are based on the current configuration. So, if a virtual machine has no current configuration (is turned off or decommissioned), it will not be included in the report.

You can click the name of an undersized VM or the *Undersized VMs* link in the **RAM analysis** table to drill down to performance details for these VMs.

You can also scroll down to see performance details for the VMs that cannot be analyzed.
