Icinga2 at large scale

Hello community, I was not sure where to put this topic, please move it if it’s under wrong category In this topic i would like to cover several questions: system requirements, possible bottlenecks and benchmarking. Hope this will simplify installation for new users and provide “ready for deploy” cluster schemas and strategy. My main goals are: define benchmarking tools for stress testing of cluster prototype define how scalable Icinga2 is, based on stress tests provide system requirements …

As @aflatto said, the master will be able to distribute downtimes etc.
That is basically what the master does: Receive check results from the satellites, distribute the config, dish out commands/downtimes/comments to hosts/services, send notifications.

Maybe the schema drawings I made some time ago also help you

Icinga 2 communication schemas

As I have posted them before, I’ll also post them here and hope they are useful for someone when figuring out a problem or explaining how Icinga 2 communicates on the inside. Icinga 2 + Icinga Web 2 + Icinga Director + Graphite [image] Icinga 2 + Icinga Web 2 + Icinga Director + PNP4Nagios [image] Hope both are correct. If not, please tell me and I will correct the error(s)
