Overview of this book

Computer virtualization is a method to enable the running of multiple application workloads on a machine to achieve efficient utilization and reduce the number of physical machines in a data center. This has now become the foundation of many modern day data centers. What began as a technology to virtualize x86 architecture has now grown beyond the limits of a server’s hardware and into the realm of storage and network virtualization. VMware is currently the market leader in developing data center virtualization solutions. This book goes into the details of designing and implementing VMware solutions that form the foundation of a VMware infrastructure. The book begins by introducing you to the concepts of server virtualization followed by the architecture of VMware’s hypervisor – ESXi and then by its installation and configuration. You then learn what is required to manage a vSphere environment and configure advanced management capabilities of vCenter. Next you are taken through topics on vSphere Networking, Storage, ESXi Clustering, Resource Management and Virtual Machine Management. You will then be introduced to SSL Certificate Management and its use in a vSphere environment. Finally, you will learn about the lifecycle management of a vSphere environment by effectively monitoring, patching and upgrading vSphere components using Update Manager. By the end of the book, you will know how to use VMware’s vSphere suite of components to lay the foundation of a modern day virtual infrastructure.

Preface

Monitoring performance


There are many different tools available to monitor the performance of a virtual infrastructure. This section will explicitly cover vSphere performance charts and esxtop.

Performance charts

Performance charts can be displayed using the vSphere Client or by using the vSphere Web Client. Throughout this chapter, we will be discussing tools that are natively available within vCenter and ESXi, but keep in mind that vRealize Operations Manager may also be used to monitor the health of your infrastructure. These performance charts can provide a great deal of useful information for an administrator to analyze performance. There are two types of charts available: overview and advanced.

Overview performance charts

Overview performance charts display the performance statistics that are most useful for quickly diagnosing problems and monitoring performance.

To view an overview performance chart:

  1. Select a virtual machine or ESXi host in the vCenter inventory pane within the vSphere...
