Pro Nagios 2.0 - Practical Guide to Nagios Deployment

In this review of Pro Nagios 2.0 the reviewer finds a focused, practical manual for system administrators and SREs who need to deploy and manage Nagios in mixed environments. The book's single biggest reason to buy is its hands-on, step-by-step configurations that move beyond theory into deployable examples; readers learn how to install Nagios, deploy agents and plug-ins, and integrate monitoring tools so systems and application availability can be actively observed and alerted on. This review highlights the book's real-world focus and when it is most useful.

Key Features

• Installation guidance: Clear instructions show how to install and configure Nagios for both Unix and Windows platforms, reducing setup uncertainty.
• Architectural advice: Explanations of Nagios architecture help plan scalable monitoring deployments and distribution of checks across hosts.
• Agent and plug-in deployment: Practical examples explain deploying agents and writing or installing plug-ins to extend monitoring coverage.
• Integration examples: Step-by-step integration with tools like MRTG and Snort demonstrates how to extend Nagios functionality for network and security monitoring.
• Real-world configurations: Included configurations and supporting materials enable rapid translation from examples to production systems.

Who It's For

Pro Nagios 2.0 is best for experienced system administrators, site reliability engineers, and small infrastructure teams who need a hands-on reference for installing and operating Nagios across mixed operating systems and network devices. Its focus on practical deployment and integration makes it useful as a field manual when configuring checks and alerts.

Less experienced readers seeking basic monitoring concepts or a gentle introduction to monitoring theory may find the book dense; beginners should complement it with more introductory materials. Also, readers seeking exclusively cloud-native, managed monitoring platform guidance should look elsewhere.

Pros & Cons

Pros

• Concrete install and configuration steps make initial deployment straightforward for administrators.
• Integration examples with MRTG and Snort add value for network and security monitoring scenarios.
• Architectural guidance helps plan scalable Nagios installations rather than single-node setups.
• Real-world configurations and supporting materials accelerate practical adoption in production.

Cons

• Focus is practical rather than introductory, so absolute beginners may need extra background reading.
• Coverage implied is centered on Nagios and traditional infrastructure; very modern managed or cloud-only workflows are not the main emphasis.

Specifications

Our Verdict

Pro Nagios 2.0 is a solid, practical reference for administrators who must deploy and manage Nagios across heterogeneous environments. Its step-by-step configurations, agent and plug-in guidance, and integration examples deliver good value to teams needing a production-ready monitoring setup rather than an academic overview.

Frequently Asked Questions

Does this book teach installation on Windows as well as Unix?
Yes. The book explains installation and administration for both Unix and Windows platforms.

Are there examples of integrating Nagios with other tools?
Yes. Pro Nagios 2.0 includes step-by-step integrations with tools such as MRTG and Snort to expand monitoring capabilities.
