## What you get

| Capability              | Description                                             |
|-------------------------|---------------------------------------------------------|
| **Custom metrics**      | Application-specific KPIs as Prometheus metrics         |
| **Custom spans**        | Trace data for your application operations              |
| **Enriched attributes** | Context on traces (user ID, order value, feature flags) |
| **Richer dashboards**   | Your custom data in standard Grafana dashboards         |

## The shift from Level 3

| Level 3                 | Level 4                                        |
|-------------------------|------------------------------------------------|
| “This request was slow” | “This $500 order from a VIP customer was slow” |
| Generic trace data      | Application-enriched traces                    |
| Infrastructure metrics  | Custom application metrics                     |

> **Same tools, richer data.** You still use Grafana alerting, SLOs, and dashboards. The difference is the data: custom metrics you defined, traces enriched with application context.
