Icinga v1.8 Released

Nürnberg, (PresseBox) - Icinga, open source monitoring solution and Nagios fork has released version 1.8 for download. Beyond new reporting features, the community-driven release presents performance and usability improvements in the core and web interfaces, responding to user requests and contributions.

Community involvement in the development of Icinga 1.8 was noteworthy in all areas of the Icinga project. In the core, this has lead to optimized handling of check results in large environments; thanks to a patch submitted to enable the check_result_list to be configured. Version 1.8 also adds a new feature to deactivate all notifications program wide with expiry, alongside many bug fixes in collaboration with user contributors.

New features abound in the Classic UI, including pagination in various views and regex-based configuration search, to make the interface user-friendlier in complex environments. In response to community requests, v1.8 Classic UI now showcases pre-defined time periods when searching logs, date picker dialogues, global refresh in the tactical header and a new command to delete downtimes of a host and all its associated services.

Similar improvements to performance and usability feature in the new Icinga Web interface. At a fundamental level, a revised credentials model reduces database join load, significantly increasing performance. Permissions for Cronks (widgets) and categories can now be edited in the front end, building on v1.7 efforts to make configurations more accessible. To further improve user experience, Icinga Web also features an enlarged status map and events integrated into the grid views to offer more information on hosts and services within a page, while clearing icon clutter.

Overall Icinga 1.8 was a community-guided project. As Icinga Core Developer Michael Friedrich reflected:

"This release really stood out for the immense community involvement. Lots of great new features were sourced from user activity in the feedback and development tracker channels, with some also contributing patches and to testing. That's what makes developing Icinga so satisfying - collaborating with other users and seeing the progress."

Icinga project members released version 1.8 during their attendance at the Open Source Monitoring Conference in Nuremberg, Germany. Alongside the new release, a second development branch, Icinga 2 was announced. Bernd Erk, Icinga Co-founder and project organizer, explained the motivation behind the parallel development branch and core framework replacement:

"With Icinga 2 we hope to build on the progress we've made with Icinga 1.x and tackle the weaknesses that were inherited in the Nagios core code base. By writing a new core framework from scratch, we can ensure that Icinga 2 is efficient in scaling in large environments, simplify configuration and generally forge a more user-friendly and intelligent monitoring system."
