# MariaDB sentiment settings, Vortex IQ Nerve Centre

> Industry-standard benchmark bands Vortex IQ AI OS uses to flag MariaDB KPIs as Performing Well or Needs Attention, and how to tune them per company.

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

Vortex IQ **AI OS** ships **industry-standard benchmark bands** for each MariaDB KPI, so your dashboard flags **Performing Well** or **Needs Attention** the moment you connect. **13** of the 31 MariaDB cards are sentiment-tuned; the rest are informational (counts, lists, breakdowns) with no good/bad direction.

The benchmarks below are a starting point grounded in industry standards. Adjust any **Good** or **Bad** threshold to match your business and **save it for your company** in **Settings → Dashboard Settings → Sensitivity**.

## How sentiment powers triage

Sentiment turns the dashboard into a focus list. Every KPI is sorted into one of three states you can filter on:

* **Performing** - comfortably inside the good band.
* **Needs Attention** - has breached the band you set. This is where to act.
* **Stable** - within range, or an informational card with no good/bad direction.

Any KPI that has not met its sentiment band is flagged **Needs Attention**, so you go straight to the handful of cards that need action instead of scanning hundreds of charts.
