Icinga

Icinga is a monitoring system which checks the availability of your network resources, notifies users of outages, and generates performance data for reporting. Scalable and extensible, Icinga can monitor large, complex environments across multiple locations. Icinga 2 is the monitoring server and requires Icinga Web 2 on top in your Icinga Stack. The configuration can be easily managed with either the Icinga Director, config management tools or plain text within the Icinga DSL. Once Icinga Server and Web are running in your distributed environment, make sure to check out the many Icinga modules for even better monitoring. Check the project website for status updates. Join the community channels for questions or ask an Icinga partner for professional support. You must obey the GNU General Public License in all respects for all of the code used other than OpenSSL. If you modify file(s) with this exception, you may extend this exception to your version of the file(s), but you are not obligated to do so. If you do not wish to do so, delete this exception statement from your version. If you delete this exception statement from all source files in the program, then also delete it here. Historically, Icinga 2 has been licensed under the GNU General Public License Version 2 or later. However, due to newly introduced dependencies licensed under the Apache License 2.0 (which is not compatible with GPLv2), we have decided to upgrade the license of Icinga 2 to GPLv3+, effective from version v2.16.0 onwards. All versions prior to v2.16.0 and all existing source code files remain licensed under GPLv2+ (see the license information in those files). If you are a packager, please read the development chapter for more details.
