In Kaspersky Security Center Cloud Console, events are stored in an event repository. You cannot configure how many events to store in the event repository.
In the Events repository section of the Administration Server properties window, you can configure the maximum storage term of events concerning to the deleted devices. The maximum storage term is 1000 days.
To configure the number of days to store events relating to the deleted devices:
The Administration Server properties window opens.
The number of days to store events concerning to the deleted devices is limited by the specified value.
Additionally, you can change the settings of any task to save events related to the task progress, or save only task execution results. In doing so, you will reduce the number of events in the database, increase the speed of execution of scenarios associated with analysis of the event table in the database, and lower the risk that critical events will be overwritten by a large number of events.
