Horizon 8 uses database tables to implement the event database. The event database prepends the names of these tables with a prefix that you define when you set up the database.
Event Database Tables
The following table shows the database tables that implement the event database in Horizon 8.
Event Database Tables
| Table Name | Description |
|---|---|
| event | Metadata and search optimization data for recent events. |
| event_data | Data values for recent events. |
| event_data_historical | Data values for all events. |
| event_historical | Metadata and search optimization data for all events. |
Horizon 8 records details about events to all the database tables. After a certain period of time has elapsed since writing an event record, Horizon 8 deletes the record from the event and event_data tables. You can use Horizon Console to configure the time period for which the database keeps a record in the event and event_data tables.
Important: Horizon 8 does not restrict the growth of the event_historical and event_data_historical tables. You must implement a space management policy for these tables.
A unique primary key, EventID, identifies each event that Horizon 8 records in the event and event_historical tables. Horizon 8 records data values for each event in the event_data and event_data_historical tables. You can obtain the complete set of information for an event by joining the event and event_data tables or the event_ historical and event_data_historical tables on the EventID column.
The EventType, Severity, and Time columns in the event and event_historical tables identify the type and severity of an event and the time at which it occurred.
For information about setting up the event database, see the Horizon 8 Installation and Upgrade document.
Note: To purge data from the historical tables, see http://kb.omnissa.com/kb/2150309.
Event Database Schemas
