# Oracle Database KPIs, Vortex IQ Nerve Centre

> Every Oracle Database KPI pulse Vortex IQ Nerve Centre tracks, with its audit profile and sentiment benchmarks.

**[Nerve Centre KPIs](/nerve-centre/kpi-cards/oracle) · [Audit Profile](/nerve-centre/kpi-cards/oracle/audit) · [Sentiment Settings](/nerve-centre/kpi-cards/oracle/sentiment)**

Vortex IQ Nerve Centre tracks **29** KPI pulses for Oracle Database. Each metric has its own page: definition, calculation, why it matters, and what to do when it moves.

The Oracle Database connector surfaces 29 KPI pulses in the Vortex IQ **AI OS** catalogue. Connect it once and every card below starts rendering automatically.
