In a first step towards greater utilization of SLA information stored in the database, Icinga responds to a longstanding request in the Icinga/Nagios community with an SLA extension. This IDOUtils module breaks down critical events to account for downtime and acknowledgement periods. In so doing it enables greater precision in SLA reporting and can be conveniently accessed from the Icinga Web interface.
Furthermore, the consequent expansion of the underlying database model and IDO2DB logic has unlocked future reporting potential. “As a preliminary version, we see this SLA extension to be our first step towards comprehensive SLA reporting, direct from the database,” illuminated Michael Friedrich, Core and IDOUtils developer.
The new development is matched only by the array of improvements to the two user interfaces. Alongside a user admin interface redesigned for greater intuitiveness, the new Icinga Web interface features a "Tackle" cronk that offers an overview of all information related to any monitoring object. Marius Hein, Icinga Web developer, explained:
“If a user specifies a certain host, the Tackle cronk will display all its related services, host groups, custom variables, contacts, comments, SLA details and more. With this cronk, users will no longer need to flip between tabs – everything is there in one view.”
Usability has also been enhanced in the Classic UI and Core. Improvements include extended logging capabilities for easier troubleshooting, notifications for stalked hosts and services, and overall greater performance, especially in notification logic.
Of note, is a new feature to set acknowledgments with expiry time. “We’re proud to say that this idea came straight out of the community – off our running, feedback poll online,” said Ricardo Bartels, Core developer as he emphasized the importance of being responsive to users as an open source project.
Version 1.6 also heralded development on a new component, IcingaMQ. Based on the ZeroMQ messaging library, the central message queue will offer a replacement for NSCA and act as a transport layer for a future Core API.
“This is a mammoth project, that will take away a whole heap of complexity in monitoring large environments, while improving performance significantly. It will add load balancing and distributed monitoring efficiencies – kind of like mod_gearman – but out of the box,” affirmed Gunnar Beutner, Core developer, as the IcingaMQ prototype was unveiled at the Open Source Monitoring Conference in Nuremberg.

– Notes To The Editor –
Icinga is an enterprise grade open source monitoring system which keeps watch over a network 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.
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. This has culminated in standout features such as PostgreSQL and Oracle database support, improved extensibility through robust REST and plugin APIs as well as a user-friendly, dynamic web interface.
