Icinga is an enterprise grade open source monitoring system which keeps watch over networks and any conceivable network resource, notifies the user of errors and recoveries and generates performance data for reporting. Scalable and extensible, Icinga can monitor complex, large environments across dispersed locations.

Icinga is a fork of Nagios® and is backward compatible. So, Nagios® configurations, plugins and addons can all be used with Icinga. 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.


  • Monitor host and service status
  • View the whole network and map dependencies
  • Gather performance and utilization data
  • Build in redundancy with distributed monitoring
  • Customize multiple users access, notifications and views

Icinga, like Nagios, has a large learning curve like any large piece of software designed to manage company resources on a large scale. However, once you get over that initial hump it's a pleasure to work with and a great community of which I enjoy participation.
