VMware Horizon 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 VMware Horizon.
| 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. |
VMware Horizon records details about events to all the database tables. After a certain period of time has elapsed since writing an event record, VMware Horizon 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.
A unique primary key, EventID, identifies each event that VMware Horizon records in the event and event_historical tables. VMware Horizon 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 Installation document.
