Nagios (http://www.nagios.org) is an open source monitoring and notification utility. It enables users to monitor various resources, such as CPU, memory, disk usage, network status, reachability, HTTP status, testing web page rendering, and various checks using Nagios-compatible sensors. There is a giant list of Nagios plugins that covers the monitoring of almost all popular services and software. The best thing with Nagios is its plugin architecture. You can write a simple plugin for custom resource monitoring. So, effectively, anything where its state can be measured, can be monitored via Nagios. This section will discuss, very briefly, Nagios setup and how it can be enabled to monitor system resources and Cassandra.

Overview of this book
<p>Apache Cassandra is the perfect choice for building fault tolerant and scalable databases. Implementing Cassandra will enable you to take advantage of its features which include replication of data across multiple datacenters with lower latency rates. This book details these features that will guide you towards mastering the art of building high performing databases without compromising on performance.</p>
<p>Mastering Apache Cassandra aims to give enough knowledge to enable you to program pragmatically and help you understand the limitations of Cassandra. You will also learn how to deploy a production setup and monitor it, understand what happens under the hood, and how to optimize and integrate it with other software.</p>
<p>Mastering Apache Cassandra begins with a discussion on understanding Cassandra’s philosophy and design decisions while helping you understand how you can implement it to resolve business issues and run complex applications simultaneously.</p>
<p>You will also get to know about how various components of Cassandra work with each other to give a robust distributed system. The different mechanisms that it provides to solve old problems in new ways are not as twisted as they seem; Cassandra is all about simplicity. Learn how to set up a cluster that can face a tornado of data reads and writes without wincing.</p>
<p>If you are a beginner, you can use the examples to help you play around with Cassandra and test the water. If you are at an intermediate level, you may prefer to use this guide to help you dive into the architecture. To a DevOp, this book will help you manage and optimize your infrastructure. To a CTO, this book will help you unleash the power of Cassandra and discover the resources that it requires.</p>
