Host Failure Modelling

Previous page Next page Print this Topic

Table of contents

The Host Failure Modelling report allows you both to simulate host failure in your Hyper-V cluster, and to forecast CPU and memory usage after the failure.

The report evaluates total capacity of your infrastructure and forecasts how many days remain before the level of CPU and memory usage in a cluster with failed host(s) 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 deviations that represent the best- and worst-case scenarios. This allows you to estimate various possible outcomes and helps you rationally plan your cluster capacities.

The report also provides recommendations on appropriate resource allocation to prevent possible CPU and memory resource shortfalls in future.

Sample Usage

This section provides step-by-step instructions that will help you understand how to create the Host Failure Modelling report. Consider the following example:

You need to model the situation when one host in a cluster fails and forecast the number of days left before the level of CPU and memory usage on remaining hosts reaches 80%. Use the historical performance data for the previous month for report analysis.

To create the report, follow these steps:

1.Open the Host Failure Modelling report.
2.Define time intervals.
3.Choose a report scope.
4.Choose how to display report charts.
5.Choose how to display report output.
6.Choose how to assess VM performance.
7.Specify threshold values.
8.Choose a number of hosts.
9.Run the report.
10.View the report output.
