View 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 View.

Table 1. 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.

View records details about events to all the database tables. After a certain period of time has elapsed since writing an event record, View deletes the record from the event and event_data tables. You can use View Administrator to configure the time period for which the database keeps a record in the event and event_data tables.

Important: View 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 View records in the event and event_historical tables. View 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 View Installation document.

Note: Events might be lost if you restart View Connection Server instances while the event database is not running. For a solution that avoids this problem see http://kb.vmware.com/kb/1021461.

Event Database Schemas

The following table shows the schema for the event and event_historical database tables.
