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.

It is recommended that you set the system time zone for all machines in your Data Warehouse deployment to UTC. This ensures that data collection is not interrupted by variations in your local time zone: for example, a change from summer time to winter time.

Data Warehouse Configuration Notes

Behavior

The following behavior is expected in engine-setup:

Install the Data Warehouse package, run engine-setup, and answer No to configuring Data Warehouse:

Configure Data Warehouse on this host (Yes, No) [Yes]: No

Run engine-setup again; setup no longer presents the option to configure those services.

Workaround

To force engine-setup to present both options again, run engine-setup --reconfigure-optional-components.

Note: To configure only the currently installed Data Warehouse packages, and prevent setup from applying package updates found in enabled repositories, add the --offline option .
