Event Manager is used to collect different events (like ATTRIBUTE_CHANGED, OBJECT_ADDED etc) from different sources and store them in one place.
Overview
The monitoring of changed statuses will be implemented to the code
Event manager reflects statuses of different objects
In case status was changed the information is sent to EventDB to be stored
This method does not guarantee the fact of storing data in EventDB
At the moment only statuses are monitored. Other events can be added in future, but they are not in a scope today.
This manager is used by MIS.
Context is not used to obtain data from DB.
Only changed statuses should be stored to EventDB, not new.\
events are transferred to event manager via Kafka
