Overview of this book

vSphere is a mission-critical piece of software for many businesses. It is a complex tool, and incorrect design and deployment can create performance related issues that can negatively affect the business. This book is focused on solving these problems as well as providing best practices and performance-enhancing techniques. This edition is fully updated to include all the new features in version 6.5 as well as the latest tools and techniques to keep vSphere performing at its best. This book starts with interesting recipes, such as the interaction of vSphere 6.5 components with physical layers such as CPU, memory, and networking. Then we focus on DRS, resource control design, and vSphere cluster design. Next, you’ll learn about storage performance design and how it works with VMware vSphere 6.5. Moving on, you will learn about the two types of vCenter installation and the benefits of each. Lastly, the book covers performance tools that help you get the most out of your vSphere installation. By the end of this book, you will be able to identify, diagnose, and troubleshoot operational faults and critical performance issues in vSphere 6.5.

Preface

Key memory performance counters to monitor


To troubleshoot memory performance in a VMware vSphere environment, you should monitor the memory performance very carefully. In this aspect, you should monitor the following counters:

  • Average memory active: The memory estimated to be used, based on recently touched memory pages.
  • Average memory swapped in or out: Virtual memory swapped to or from disk.
  • Average memory swapped: Total amount of memory swapped out. This indicates a possibility (with an unknown likelihood) of poor performance in future.

Getting ready

To step through this recipe, you will need a running ESXi Server, a couple of running VMs with VMware Tools installed, and vSphere Web Client. No other prerequisites are required.

How to do it...

To spot the average Active Memory, you should check both the VM level and host level. To monitor at the VM level, perform the following steps:

  1. Open up vSphere Web Client.
  2. Log in to your vCenter Server.
  3. On the Home screen, select VMs and Templates.
  4. Choose the...
