Chapter 9: Data Warehouse and Reports
Overview of Configuring Data Warehouse
The oVirt Engine includes a comprehensive management history database, which can be utilized by any application to extract a range of information at the data center, cluster, and host levels. Installing Data Warehouse creates the
ovirt_engine_history database, to which the Engine is configured to log information for reporting purposes. The Data Warehouse component is optional.
