Icinga 2 is an extensible monitoring system designed to check resource availability, notify users of outages, and provide detailed metrics. The document details its features such as multithreading, modular components, and support for automation and multitenancy through configuration rules. It also encourages users to experiment with Icinga 2 and Icinga Web 2, providing resources for further exploration and feedback.

Editor's Notes
- #10: Automate Installation Automate Configuration
- #12: Alles ist ein Objekt
- #13: A simple object Inherits from a template Custom Variable
- #15: Rule instead of many services Works also for notifications
- #18: Multiple vHosts on one host Could also be a Database
- #19: Iterate over a hash / dictoinary
- #21: Multiple vHosts on one host Could also be a Database
- #27: Status API Permissions Debug
- #29: Alle Objekte per Webinterface
- #30: Import Objects For instance from CMDB Create custom vars
- #31: A simple object Inherits from a template Custom Variable
