Nagios Introduction

Nagios is, an open-source computer-software application, monitors systems, networks and infrastructure. Nagios offers monitoring and alerting services for servers, switches, applications and services. It alerts users when things go wrong and alerts them a second time when the problem has been resolved.

Nagios was originally designed to run under Linux, but it also runs well on other Unix variants. It is free software licensed under the terms of the GNU General Public License version 2 as published by the Free Software Foundation.

Nagios monitors your entire IT infrastructure to ensure systems, applications, services, and business processes are functioning properly. In the event of a failure, Nagios can alert technical staff of the problem, allowing them to begin remediation processes before outages affect business processes, end-users, or customers. With Nagios you’ll never be left having to explain why an unseen infrastructure outage hurt your organization’s bottom line.

OEM doesn't mean Original Engineering Manufacturers, it means Original Equipment Manufacturers, also Open-Source doesn't mean it's free of cost.

Hi, thank you for teaching how to Nagios! We added your video to our "Nagios Presentations" playlist on the Nagios Community channel.

Great Effort bro ! Its an outstanding video. Thanks

Available "Open Source" does not mean it's always available free of "charge". Eg: Qt Framework is opensource but still if you want to use it for developing closed source application, the Qt team will charge you for it. You may want to correct this.
