# SQLite KPIs, Vortex IQ Nerve Centre

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

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

Vortex IQ Nerve Centre tracks **14** KPI pulses for SQLite. Each metric has its own page: definition, calculation, why it matters, and what to do when it moves.

The SQLite connector surfaces 14 KPI pulses in the Vortex IQ **AI OS** catalogue. Connect it once and every card below starts rendering automatically.
