# Performance Assessment

This report evaluates whether the Microsoft Hyper-V infrastructure is configured optimally, helps find potential issues and suggests actions aimed at boosting its efficiency. The report analyzes data over the past 2 weeks and checks whether performance thresholds are exceeded or the number of times Veeam ONE Client triggered *Error* and *Warning* alarms. Performance thresholds are defined in alarm counters in Veeam ONE Client. If a threshold is exceeded, the report will deliver *Warning* or *Error* verification result depending on counter settings.

- The **Summary** section includes the following elements:

  - The **Verification Result** chart displays the share of failed and passed verification tests, test that are not applicable, and tests that completed with warnings.
  - The **Assessment Criteria** table lists criteria used in the report to evaluate Hyper-V infrastructure performance, and shows the assessment results. 

- The **Performance** tables show detailed assessment result for each criterion and provides recommendations on how to improve infrastructure performance.

The report takes into account the following criteria when analyzing performance parameters:

## Report Parameters

You can specify the following report parameters:

- **Infrastructure objects**: defines a virtual infrastructure level and its sub-components to analyze in the report.
- **Business View objects**: defines Business View groups to analyze in the report. The parameter options are limited to objects of the Host type.

  Business View groups from the same category are joined using Boolean OR operator, Business View groups from different categories are joined using Boolean AND operator. That is, if you select groups from the same category, the report will contain all objects that are included in groups. However, if you select groups from different categories, the report will contain only objects that are included in all selected groups.

- **Network bandwidth**: defines network bandwidth to analyze in the report.
- **Areas to assess**: defines a type of resources to analyze in the report (*All*, *CPU*, *Memory*, *Disk*, *Network*).
