Practical DevOps

Overview of this book

DevOps is a practical field that focuses on delivering business value as efficiently as possible. DevOps encompasses all the flows from code through testing environments to production environments. It stresses the cooperation between different roles, and how they can work together more closely, as the roots of the word imply—Development and Operations. After a quick refresher to DevOps and continuous delivery, we quickly move on to looking at how DevOps affects architecture. You'll create a sample enterprise Java application that you’ll continue to work with through the remaining chapters. Following this, we explore various code storage and build server options. You will then learn how to perform code testing with a few tools and deploy your test successfully. Next, you will learn how to monitor code for any anomalies and make sure it’s running properly. Finally, you will discover how to handle logs and keep track of the issues that affect processes

Graphite


While Munin is nice because it is robust and fairly easy to start using, the graphs it provides are only updated once in a while, normally every fifth minute. There is therefore a niche for a tool that does graphing that is closer to real time. Graphite is such a tool.

The Graphite stack consists of the following three major parts. It is similar to both Ganglia and Munin but uses its own component implementations.

  • The Graphite Web component, which is a web application that renders a user interface consisting of graphs and dashboards organized within a tree-like browser widget

  • The Carbon metric processing daemon, which gathers the metrics

  • The Whisper time series database library

As such, the Graphite stack is similar in utility to both Munin and Ganglia. Unlike Munin and Ganglia though, it uses its own time series library, Whisper, rather than an RRD.

There are several prepackaged Docker images for trying out Graphite. We can use the sitespeedio/graphite image from the Docker Hub, as follows...
