The Performance Forecast for Hyper-V Clusters report forecasts CPU and memory resource utilization for Hyper-V clusters.
The report forecasts how many days remain before the level of CPU and memory resource utilization reaches the specified threshold values.
To calculate future cluster performance, the report analyzes historical performance data for the specified period in the past, calculates the performance utilization trend and applies this trend to the forecast horizon. For better forecast accuracy, along with the performance trend the report provides trend's confidence interval that represents the best- and worst-case scenarios. This allows you to estimate various possible outcomes and helps you rationally plan your resources.
If one or more specified thresholds are breached within the forecast interval, the report marks the cluster as problematic and lists constraining resources for it. The report also provides recommendations on appropriate resource allocation to prevent possible CPU and memory resource shortfalls in future.
This section provides step-by-step instructions that will help you understand how to create the Performance Forecast for Hyper-V Clusters report. Consider the following example:
You need to forecast the number of days left before the level of CPU and memory usage for the selected cluster reaches 90%. Make sure that this threshold will not be breached within the next 30 days. Use the historical performance data for the previous month to calculate utilization trend.
To create the report, follow these steps:
- Open the Performance Forecast for Hyper-V Clusters report.
- Define time intervals.
- Choose a report scope.
- Define a resource to be analyzed.
- Choose how to display report charts.
- Choose how to display report output.
- Specify threshold values.
- Run the report.
- View the report output.
