Icinga is a powerful monitoring tool!

Icinga shares similarities with Nagios in its basic monitoring capabilities, but has gone a few features above and beyond. Though Icinga retains all the existing features of its predecessor, it builds on them to add many long awaited patches and features requested by the user community.

ICINGA 2: Concurrent to improving Icinga as a fork of Nagios, the Icinga Project is also actively developing Icinga 2. There are two development branches: Icinga 1.x (Nagios fork) and Icinga 2 (Core framework replacement / Nagios rewrite). Where “Icinga” is mentioned in our website and blog posts, we are referring to Icinga 1.x.

Flexible and Modular Architecture

Icinga consists of Icinga Core, Icinga Web, a database (currently MySQL / Oracle / PostgreSQL), plugins and addons of your choice. These communicate via Icinga’s Doctrine abstraction layer, REST and plugin API’s – that mediate between external data and internal structures. This bundling of components allows you to distribute Icinga’s system for redundant monitoring. It also offers the freedom to customise Icinga to suit your needs. More on Icinga’s architecture…

New Dynamic Web Interface

Based on an Agavi framework, driven by Ajax and enhanced by ExtJs, Json and CSS, Icinga Web stands out from the crowd. Its widget architecture offers a highly customisable dashboard interface that easily integrates addons. The new interface was built with user friendliness in mind. Alongside a powerful search function, real-time status views can be filtered and sorted to get you the information you need faster. More on Icinga new and classic web interfaces.

Enterprise Grade Extensibility & Authentication

From one to thousands of hosts, services, instances – Icinga’s plugin and modular structure offers limitless extensibility. Aside from the fact that all Nagios extensions are Icinga compatible, Icinga’s own Doctrine abstraction layer, REST and plugin APIs make designing new extensions even easier. This is topped off with a highly refined authentication system which enables user access, notifications and views to be customised to the detail of server groups, servers and services per individual.

100% Open Source & Community Driven

Icinga was forked from Nagios with a clear objective to preserve its open source nature. Icinga in all its versions are available under GPL and will always remain to be. That’s because Icinga is developed by a large team of monitoring enthusiasts from around the world. So bug fixes and new features are constantly released and Icinga’s public roadmap is testimony to the team’s commitment. More on the Icinga Community…

Designed to Make Monitoring Easier

Icinga is consistently being fortified with new components, extensions and accessories to make monitoring more convenient for you. More recent innovations include:

  • Icinga Mobile – User interface for your smart phone
  • Icinga Reporting – Convenient report generation & distribution in Icinga Web based on Jasper Reports
  • Virtual Appliance – Icinga pre-packaged with all basic components for easy installation
  • Business Process Addons for Icinga – Monitor entire applications and business processes in Icinga Web
  • PNP Graphing for Icinga – Integrated performance charts

Icinga vs. Nagios

Though Nagios configurations, plugins and addons are compatible with Icinga, the two software have marked differences. From the architecture and core capabilities, to the two web interfaces and API context, Icinga sets itself apart in both technology and development spirit. More on Icinga compared to  Nagios…
