The Icinga DB is the successor to the IDO (Icinga Data Output).
It is a set of components for publishing, synchronizing and visualizing monitoring data in the Icinga ecosystem.
It consists of:
- The Icinga DB daemon, which synchronizes monitoring data between a Redis®* server and a database
- Icinga 2 with its Icinga DB feature enabled, responsible for publishing the data to the Redis® server, i.e. configuration and its runtime updates, check results, state changes, downtimes, acknowledgements, notifications, and other events such as flapping
