About the course

Nagios is an open-source monitoring tool originally created to run on Linux, but you can also run it on other Unix systems. It was released in 1999 and has over 1 million users worldwide today. Nagios has many features, most of which relate to monitoring. It can track systems, network services, applications, host resources, and infrastructure. It enables you to define parent-child relationships between hosts, create parallelized service checks, define many kinds of event handlers to aid in solving problems, and much more. Nagios is an important tool because you can use it to detect numerous kinds of server or network problems. It assists with finding the cause of problems so you can fix them as soon as possible. In urgent circumstances, Nagios can even automatically fix issues. In short, you’ll find Nagios substantially simplifies system monitoring.

The aim of this course is to prepare individuals for the Nagios Certified Professional – Core exam. We do this using different learning methods. First, all necessary material is explained through the videos. You also have hands-on labs in each section to provide you with practical knowledge. Finally, to help you practice and prepare, you have various supplementary materials like final exam practice questions and additional exercises.

There are six main sections we go over throughout the course. The beginning of the course starts teaching you what Nagios is, what it’s used for, the prerequisites for using Nagios, and an overview of the most important Nagios terminology. This is important so that you can fully understand key terms like a state, contact group, or acknowledgment. We spend time on learning how to download and install Nagios properly and configuring its many necessary plugins. In User and Server Management, you learn about user administration, navigating the Nagios interface, creating event handlers, host/service groups, reachability, and managing both time and downtime in Nagios. In Monitoring, we talk about plugins, SNMP, and monitoring systems. Finally, we cover NSCA and V-shell to broaden your Nagios knowledge even further.

By the end of this course, you’ll understand all the key concepts of Nagios, be able to create custom configuration files, and set Nagios up to your liking.
