Websites using Nagios

Okay, let s break down Nagios, covering its overview, revenue (or lack thereof), alternatives, pricing, and customer care.

Nagios: An Overview

Nagios is a widely used, open-source system and network monitoring application. It s known for its flexibility and ability to monitor a vast array of services, hosts, and network devices. Here s a closer look:

• Core Functionality: Nagios primarily focuses on:
  • Monitoring: Checks the status of hosts (servers, workstations, etc.) and services (web servers, databases, etc.) across a network.
  • Alerting: Sends notifications (email, SMS, etc.) when problems are detected, allowing for proactive issue resolution.
  • Reporting: Provides historical data and reports on monitored elements, aiding in capacity planning and performance analysis.
• Architecture: Nagios has a core engine that handles scheduling and checks, and it uses plugins to perform the actual monitoring tasks. This plugin-based architecture makes it highly extensible.
• Open Source: Being open source, Nagios is free to use, modify, and distribute. This fosters a strong community and allows for customizations.
• Web Interface: Nagios comes with a web interface that provides a view of the network status, alerts, and reports.
• Target Audience: Nagios caters to system administrators, IT professionals, and DevOps teams who need to monitor the health and performance of their infrastructure.

Revenue Model: Lack of Direct Revenue for the Core

Here s a crucial point: Nagios (the core open-source software) does not generate direct revenue. It is a community-driven project supported by volunteers and contributions.

However, there is revenue around the Nagios ecosystem:

• Nagios Enterprises: This is a commercial company that offers:
  • Nagios XI: A paid, commercial version of Nagios, providing an enhanced user interface, additional features, and enterprise support. This is where Nagios Enterprises generates its revenue.
  • Support Contracts & Training: Nagios Enterprises also offers paid support and training services for both Nagios Core and Nagios XI.
