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

Chapter 9. Monitoring Performance of a vSphere Environment

In this chapter, we will discuss performance and discover how vSphere administrators can monitor the resource usage of different inventory objects. It is important to monitor the vSphere infrastructure to determine if there is a resource bottleneck or if a virtual machine or ESXi host is experiencing constraint. There are many tools that are available within vSphere that can assist VMware administrators to monitor resources and detect any potential bottlenecks. Both esxtop and performance charts are natively available within vSphere for monitoring. Alarms may also be configured to alert administrators when specific events occur or when thresholds are exceeded. In this chapter, you will learn about:

  • CPU performance considerations

  • Memory performance considerations

  • Network performance considerations

  • Storage performance considerations

  • Resource controls

  • vSphere performance charts

  • esxtop

  • Alarms
