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

Syslog


Each ESXi host runs a syslog service that is used to log VMkernel messages, as well as messages from other system components, to a set of log files.

Syslog settings may be modified using the vSphere Web Client.

To do so:

  1. Using the vSphere Web Client, navigate to an ESXi host in the inventory.

  2. Go to the Manage tab and select the Settings button.

  3. Choose Advanced System Settings underneath the System section.

  4. Search syslog in the query section, as demonstrated in the following screenshot:

  5. The following syslog values may be changed:

    • Syslog.global.defaultRotate: This setting specifies the maximum number of logs to keep.

    • Syslog.global.defaultSize: This setting specifies the default size of a log, in KB, before a log is rotated by the system.

    • Syslog.global.LogDir: This setting specifies the directory in which logs are stored. This can be an NFS or VMFS datastore.

    • Syslog.global.logDirUnique: This setting creates a unique subdirectory with the name of the ESXi host.

    • Syslog.global.LogHost: This setting...
