# ET-SAAS-016: Especificacion Tecnica - Analytics Dashboard

## Metadata
- **Codigo:** ET-SAAS-016
- **Modulo:** Analytics
- **Version:** 1.0.0
- **Estado:** Implementado
- **Fecha:** 2026-01-24
- **Basado en:** Metabase patterns, SaaS analytics best practices

---

## 1. Resumen Ejecutivo

### 1.1 Estado Actual

No existe modulo de analytics implementado. Los datos para metricas existen en:

| Fuente | Datos Disponibles | Accesibilidad |
|--------|-------------------|---------------|
| users.users | Total usuarios, fechas creacion | Directa |
| billing.subscriptions | MRR, planes activos | Directa |
| billing.invoices | Revenue por periodo | Directa |
| auth.sessions | Usuarios activos (login) | Indirecta |
| audit.audit_logs | Acciones por usuario | Directa |
| storage.files | Uso de storage | Directa |
| ai.ai_usage | Tokens AI consumidos | Directa |

### 1.2 Propuesta v1.0

Dashboard de analytics con:

- **KPIs en tiempo real**: Usuarios, MRR, uso de recursos
- **Tendencias temporales**: Graficos de 7d, 30d, 90d, 1y
- **Breakdowns**: Por plan, por tenant, por recurso
- **Cache inteligente**: Metricas pre-calculadas
- **Superadmin view**: Metricas globales agregadas

---

## 2. Metricas Definidas

### 2.1 Metricas de Usuarios

| ID | Metrica | Formula | Granularidad |
|----|---------|---------|--------------|
| U1 | total_users | COUNT(users) | Snapshot |
| U2 | active_users_7d | Users con login en 7 dias | Rolling |
| U3 | active_users_30d | Users con login en 30 dias | Rolling |
| U4 | new_users | Users creados en periodo | Period |
| U5 | churned_users | Users inactivos > 30 dias | Period |
| U6 | churn_rate | churned / total * 100 | Period |
| U7 | dau | Users activos hoy | Daily |
| U8 | mau | Users activos 30d | Monthly |

### 2.2 Metricas de Billing

| ID | Metrica | Formula | Granularidad |
|----|---------|---------|--------------|
| B1 | mrr | SUM(subscription.price) WHERE active | Snapshot |
| B2 | arr | MRR * 12 | Calculated |
| B3 | revenue_period | SUM(invoices.amount) WHERE paid | Period |
| B4 | arpu | revenue / users | Period |
| B5 | subscriptions_active | COUNT(active subs) | Snapshot |
| B6 | subscriptions_new | Subs creadas en periodo | Period |
| B7 | subscriptions_churned | Subs canceladas en periodo | Period |
| B8 | ltv | ARPU * avg_lifetime | Calculated |

### 2.3 Metricas de Uso

| ID | Metrica | Formula | Granularidad |
|----|---------|---------|--------------|
| R1 | api_calls | COUNT(requests) | Period |
| R2 | api_calls_by_endpoint | GROUP BY endpoint | Period |
| R3 | storage_used_gb | SUM(file_size) / 1GB | Snapshot |
| R4 | storage_by_type | GROUP BY mime_type | Snapshot |
| R5 | ai_tokens | SUM(tokens_used) | Period |
| R6 | ai_tokens_by_model | GROUP BY model | Period |
| R7 | notifications_sent | COUNT(sent) | Period |
| R8 | webhooks_delivered | COUNT(delivered) | Period |

### 6.2 TrendChart Component

```tsx
import { LineChart, Line, XAxis, YAxis, CartesianGrid, Tooltip, ResponsiveContainer } from 'recharts';

interface TrendChartProps {
  data: TimeseriesData[];
  height?: number;
}

export const TrendChart: React.FC<TrendChartProps> = ({ data, height = 300 }) => {
  return (
    <ResponsiveContainer width="100%" height={height}>
      <LineChart data={data}>
        <CartesianGrid strokeDasharray="3 3" />
        <XAxis dataKey="date" />
        <YAxis />
        <Tooltip />
        <Line
          type="monotone"
          dataKey="value"
          stroke="#3B82F6"
          strokeWidth={2}
          dot={false}
        />
      </LineChart>
    </ResponsiveContainer>
  );
};
```

### 6.3 Hooks

```typescript
export const useAnalyticsSummary = (period: string) => {
  return useQuery({
    queryKey: ['analytics', 'summary', period],
    queryFn: () => analyticsApi.getSummary(period),
    staleTime: 5 * 60 * 1000, // 5 minutes
  });
};

export const useAnalyticsTrends = (metrics: string[], period: string) => {
  return useQuery({
    queryKey: ['analytics', 'trends', metrics, period],
    queryFn: () => analyticsApi.getTrends(metrics.join(','), period),
    staleTime: 5 * 60 * 1000,
  });
};
```

- [ ] Graficos de tendencias renderizan con Recharts
- [ ] Cache de metricas reduce queries a BD
- [ ] Jobs programados calculan metricas hourly/daily
- [ ] Superadmin puede ver metricas globales
- [ ] Exportacion de datos funciona (JSON, CSV)

## 8. Riesgos y Mitigaciones

| Riesgo | Probabilidad | Impacto | Mitigacion |
|--------|--------------|---------|------------|
| Queries lentas | Alta | Alto | Indexes + cache + jobs |
| Cache stale | Media | Medio | TTLs cortos + invalidation |
| Datos incorrectos | Baja | Alto | Tests + validacion cruzada |
| Alto uso CPU | Media | Medio | Jobs en horarios off-peak |
