Course Overview: What is Nagios and What Will You Learn?
First, let’s understand what Nagios is. Nagios Core is an open-source monitoring framework that has become an industry standard. Think of it as a 24/7 watchman for your entire network. It runs on systems like Linux and constantly checks the health of servers, network devices, and applications. If something stops working, Nagios immediately sends an alert, allowing IT teams to fix problems before users are affected.
The Nagios training in Kolkata from DevOpsSchool is designed to transform you from a beginner into a confident Nagios administrator. The course is intensive yet focused, lasting approximately 8 to 12 hours, and is packed with practical, hands-on learning.
By the end of this comprehensive training, you will know how to:
- Install and Configure Nagios: Set up the monitoring system from scratch.
- Monitor Everything: Keep an eye on network devices, servers (both Linux and Windows), and specific services.
- Master Key Components: Work with plugins, configure the NRPE (Nagios Remote Plugin Executor) for remote monitoring, and set up notifications.
- Create Effective Structures: Define host groups and service groups to organize your monitoring logically.
- Handle Advanced Scenarios: Configure service dependencies, schedule checks and notifications, and set up event handlers for automatic responses.
The training is not just theory. About 80-85% of the course is hands-on, ensuring you gain real skills by actually working with the tool in a lab environment. This practical approach means you’ll be job-ready from day one.
