Overview of this book

VMware NSX is at the forefront of the software-defined networking revolution. It makes it even easier for organizations to unlock the full benefits of a software-defined data center – scalability, flexibility – while adding in vital security and automation features to keep any sysadmin happy. Software alone won’t power your business – with NSX you can use it more effectively than ever before, optimizing your resources and reducing costs. Getting started should be easy – this guide makes sure it is. It takes you through the core components of NSX, demonstrating how to set it up, customize it within your current network architecture. You’ll learn the principles of effective design, as well as some things you may need to take into consideration when you’re creating your virtual networks. We’ll also show you how to construct and maintain virtual networks, and how to deal with any tricky situations and failures. By the end, you’ll be confident you can deliver, scale and secure an exemplary virtualized network with NSX.

Preface

NSX Controller log collection


Controller is the real game changer component in the overall architecture of NSX. For the same reason, it remains a critical piece when it comes to troubleshooting. As we all know, controllers are deployed from NSX Manager in an Open Virtualization Appliance (OVA). In a worst-case scenario, even the deployment of controllers might fail, and that would be a showstopper for any NSX implementation. The majority of such failures happen for the following two reasons:

  • DNS

  • NTP

There should be proper DNS/NTP configuration between ESXi hosts, vCenter Server, and NSX Manager for a successful deployment of NSX Controller. Apart from this point, a successful deployment of any virtual machine in vSphere certainly needs enough compute and storage capacity, and NSX Controller is no exception, primarily because these are virtual machines from an ESXi host perspective. For collecting NSX Controller logs, we need to complete the following steps:

  1. Firstly, we need to log in to vCenter...
