Metric kinds
| Kind | What it is |
|---|---|
| Primitive | A single aggregation over one field |
| Ratio | One metric divided by another |
| Derived | A formula referencing other metrics |
| Engine | A platform-computed metric backed by a calculation |
Why a registry
- No drift. Every surface that shows a metric reads the same definition, so the same number means the same thing on every screen.
- Traceable. Click a metric anywhere to see its definition, formula, and a drill-through.
- Versioned. Changing a definition bumps its version, so history stays honest.
Adding a metric
Create it
In Reporting -> Metrics Center, choose a kind and define it. For derived metrics, the
formula editor autocompletes references to other metrics.
