Monitoring as Code - Ignite
Download as PPTX, PDF1 like1,241 views
Icinga is a scalable and extensible monitoring system that checks resource availability, notifies users of outages, and provides metrics. It uses an object-based configuration language to define hosts, services, rules, conditions, loops and custom functions. Configurations can be imported from various sources and managed through a RESTful API or web interface. Icinga Director allows importing configurations from multiple sources, deploying them hands-free with versioning and audit logging.
![object Host "demo.icinga.com" {
import "generic-host"

}
vars.http_vhosts["Grafana"] = {
http_port = 3000
}
}

Editor's Notes
- #4: making sth. worse by trying to make it better
- #8: A simple object Inherits from a template Custom Variable
- #9: Rule instead of many services Works also for notifications
- #10: Multiple vHosts on one host Could also be a Database
- #11: Iterate over a hash / dictoinary
- #14: Status API Permissions Debug
- #15: Alle Objekte per Webinterface
- #16: Import Objects For instance from CMDB Create custom vars
- #17: A simple object Inherits from a template Custom Variable
