Icinga 2 is a great alternative to Nagios

Icinga 2 is a great[ alternative to Nagios](http://shadow-soft.com/alternative-to-nagios/ )

n 2009, a group of Nagios community developers left to create a better network monitoring tool – Icinga. Also released as Open Source, Icinga better reflects the wishes of the community and changing needs of the IT marketplace. Icinga overcomes many obstacles found within Nagios and continues to demonstrate a pattern of growth, releasing new versions every few months.

  • With Icinga 2, the developers rewrote the core code, correcting many shortcomings like improving complicated configuration and improving scalability limitations in large deployments.
  • Icinga 2’s core was also rewritten in C++ with a new component-loader architecture and process for executing monitoring checks. Worldwide market acceptance of Icinga 2 has been overwhelming.
  • Icinga 2 can use the broad array of common Nagios monitoring plugins, whether they run on the monitoring server or on the local client.
  • The Icinga Web 2 interface is more flexible and extensible than the basic grid interface provided by Nagios.
  • The rewrite of Nagios (Icinga 1) significantly improved the efficiency of the monitoring code, and in the redesign we know as Icinga 2 this has been retained as a key design principle.
