Introduction
In our digital world, computer systems are like the beating heart of every business. For a hospital, it’s the patient records system. For a bank, it’s the online transaction servers. For an e-commerce store in Kolkata, it’s the website and payment gateway. What happens if that heartbeat stops? The result can be lost money, broken trust, and a lot of stress.
This is where Nagios becomes an absolute hero. Think of Nagios as a smart, 24/7 watchguard for your entire IT infrastructure. It’s the industry’s leading open-source monitoring tool that constantly checks if your servers, network switches, applications, and services are alive and healthy. The moment something goes wrong, Nagios sends an alert so you can fix it before your users even notice.
For IT professionals in Kolkata’s growing tech scene, knowing how to use Nagios is not just a skill—it’s a career superpower. If you’re looking to master this critical tool, DevOpsSchool offers top-notch Nagios training in Kolkata. This course is designed to take you from understanding the basics to becoming an expert who can build a rock-solid monitoring system for any organization.
Course Overview: What Will You Actually Learn?
The Nagios training program at DevOpsSchool is focused, practical, and designed to make you job-ready. The course dives deep into Nagios Core, the powerful, free engine that powers monitoring for thousands of companies worldwide. The goal is simple: to move beyond just running default checks and unlock the full potential of the framework to make it the centerpiece of your network operations.
The training is an intensive 8 to 12 hours, packed with real knowledge. You can choose how you want to learn:

So, what’s on the syllabus? Here’s a clear look at the valuable skills you’ll gain:
- The Foundation: You’ll start by understanding why infrastructure monitoring is crucial, learn about Nagios plugins, and get hands-on with installing Nagios from scratch.
- Core Configuration: This is where you learn to tell Nagios what to monitor. You’ll define hosts (like your web server), services (like HTTP or disk space), and organize them into groups for easy management.
- Smart Monitoring: Learn to monitor not just Linux servers but also Windows machines using NSClient++. You’ll set up smart alerting to avoid notification floods and configure dependencies (so you don’t get 100 alerts when one root server fails).
- Remote Checks & Automation: Master the NRPE (Nagios Remote Plugin Executor) to securely monitor resources on remote servers. You’ll also learn to write event handlers to automate responses to common problems.
- Reporting & Maintenance: Learn how to schedule checks efficiently, understand plugin outputs, and keep your Nagios system running smoothly.
