21.2.1. Red Hat Enterprise Virtualization History Database
Red Hat Enterprise Virtualization Reports uses data from the Red Hat Enterprise Virtualization History Database (called
ovirt_engine_history) which tracks the engine database over time.
Important
Sufficient data must exist in the history database to produce meaningful reports. Most reports use values aggregated on a daily basis. Meaningful reports can only be produced if data for at least several days is available. In particular, because trend reports are designed to highlight long term trends in the system, a sufficient history is required to highlight meaningful trends.
