Let’s explore how this training can help you become a monitoring expert.
Course Overview: What You Will Learn
The Nagios training program at DevOpsSchool is a focused, hands-on journey into the world of professional system monitoring. The course is built around Nagios Core, the powerful open-source engine that has become a standard on Unix and Linux systems worldwide. The goal is simple: to move beyond basic, default checks and unlock the full potential of the framework.
The course is structured to be practical and comprehensive. Over 8 to 12 hours of intensive learning, you will dive deep into both the “how” and the “why” of Nagios operations. The training is available in flexible formats to suit your needs: self-paced video learning, live interactive online batches, one-on-one sessions, or corporate training.
Here’s a snapshot of the key skills you will master:
- Foundation & Setup: You will learn to install Nagios from scratch, understand its dependencies, and configure its web interface (CGI).
- Core Configuration: The course covers how to set up and manage the heart of monitoring—defining hosts, services, host groups, and service groups.
- Advanced Monitoring Techniques: Learn to monitor everything from network devices to Windows servers (using NSClient++). You’ll understand critical concepts like check scheduling, flapping detection, and setting up service and host dependencies to reduce alert noise.
- Extended Functionality: You will install and configure the NRPE (Nagios Remote Plugin Executor) to monitor local resources from a central server and learn to write effective event handlers for automated problem resolution.
- Alerting & Reporting: Master the art of notification—scheduling alerts, defining commands, and ensuring the right people get the right information at the right time.
By the end of this Nagios course, you’ll be able to design, implement, and manage a robust monitoring solution that provides true visibility into your IT environment.
