Overview of this book

In this second edition, you will get to grips with the latest features of OpenStack. Starting with an overview of the OpenStack architecture, you'll see how to adopt the DevOps style of automation while deploying and operating in an OpenStack environment. We'll show you how to create your own OpenStack private cloud. Then you'll learn about various hypervisors and container technology supported by OpenStack. You'll get an understanding about the segregation of compute nodes based on reliability and availability needs. We'll cover various storage types in OpenStack and advanced networking aspects such as SDN and NFV. Next, you'll understand the OpenStack infrastructure from a cloud user point of view. Moving on, you'll develop troubleshooting skills, and get a comprehensive understanding of services such as high availability and failover in OpenStack. Finally, you will gain experience of running a centralized logging server and monitoring OpenStack services. The book will show you how to carry out performance tuning based on OpenStack service logs. You will be able to master OpenStack benchmarking and performance tuning. By the end of the book, you'll be ready to take steps to deploy and manage an OpenStack cloud with the latest open source technologies.

Monitoring and Troubleshooting - Running a Healthy OpenStack Cluster

"To accept something on mere presumption and, likewise, to fail to investigate it may cover over, blind, and lead astray."
- Abu Nasr Al-Farabi

A functional OpenStack cloud environment cannot be achieved without having full control of every piece and component running in it. Being a proponent of keeping an eye on the resources and services running the OpenStack infrastructure is a step in the right direction. Monitoring is not limited to defining which problems can appear and how to react against them, but also is a pre-maintenance exercise where operators report the trend of resources usage and decide how the cloud architecture can be adjusted in terms of design and deployment. As you will learn in this chapter, the Telemetry...
