## Analytics Engine Services

### Service 1: `aamos-analytics-engine` (:3211)
**Binary:** `/opt/amos/rust/analytics-engine/target/release/amos-analytics`  
**Systemd:** `/etc/systemd/system/aamos-analytics-engine.service`

**Endpoints:**
| Endpoint | Status | Beskrivning |
|---|---|---|
| `GET /health` | ✅ 200 | `{"status":"ok","service":"amos-analytics","port":3211,"clickhouse":"ok"}` |
| `GET /api/analytics/dau?days=N` | ✅ 200 | Daily Active Users från events-tabell |
| `GET /api/analytics/mrr?months=N&product=X` | ✅ 200 | MRR från analytics_mrr |
| `GET /api/analytics/cohort?product=X&periods=N` | ✅ 200 | Cohort retention |
| `POST /api/analytics/events` | ❌ 404 | Finns ej — inget event-ingest endpoint |

**Notering:** Service initierar DDL-schema (CREATE TABLE IF NOT EXISTS) vid start, och seedar om analytics_mrr är tom.

### Service 2: `amos-analytics-rust` (:3281) — STUB
**Binary:** `/opt/amos/rust/analytics-rust/target/release/amos-analytics-rust`  
Denna är en **stub/placeholder** utan ClickHouse-integration.  
Endpoints: `/health`, `/status`, `/list`, `/create` — returnerar tomma svar.

## Test-event
Skickades direkt till ClickHouse (analytics-engine har inget POST-endpoint):

```bash
curl -X POST "http://localhost:8123/?user=aamos&password=aamos_wh_2026&database=aamos" \
  --data-binary "INSERT INTO events (event_type, entity_id, entity_type, properties, source, ts) 
    VALUES ('test', generateUUIDv4(), 'test', 
    '{\"source\":\"e1-008-test\",\"tenant_id\":\"wavult-group\"}', 
    'e1-008-test', now())"
```

**Resultat:** ✅ Insertat — DAU-endpoint returnerade `{"days":1,"series":[{"date":"2026-06-05","dau":1}],"avg_dau":1.0,"peak_dau":1}`

## MRR-data (aktuell)
Från `/api/analytics/mrr?months=3`:

| Produkt | MRR (Juni 2026) | Kunder | MoM-tillväxt |
|---|---|---|---|
| aamos | 2 914 549 SEK | 727 | ~8% |
| quixzoom | 3 195 032 SEK | 3 592 | ~14% |
| ouroboros | 2 551 313 SEK | 79 | ~6% |
| **TOTALT** | **8 660 894 SEK** | - | **9.52%** |

## ⚠️ Nginx-upstream — Portmismatch

**Problem:** Nginx-upstream pekar på fel port!

```nginx
# /etc/nginx/conf.d/aamos-upstreams.conf
upstream rust_analytics { server 127.0.0.1:3281; keepalive 16; }

# /etc/nginx/snippets/rust-services.conf
location /api/svc/analytics/ {
    proxy_pass http://rust_analytics/;  # → :3281 (STUB!)
}
```

- `rust_analytics` upstream → `:3281` = **stub-service** (ingen ClickHouse-integration)
- Faktiska analytics-engine med data → `:3211` = **ej proxad**

**Rekommendation:** Uppdatera upstream till `127.0.0.1:3211` (kräver root/SSM).  
Eller registrera `:3211` som ny upstream `rust_analytics_engine` och uppdatera location-blocket.

---

## Sammanfattning

- **Schema:** Komplett. 12 tabeller i `aamos`-databasen.
- **Data:** analytics_mrr (36 rader) och analytics_cohort (126 rader) är seedade med realistisk data.
- **Analytics-engine (:3211):** Fullt fungerande. DAU, MRR, Cohort-endpoints svarar korrekt.
- **Test-event:** Verifierat via direkt ClickHouse-insert. DAU-endpoint plockar upp det.
- **Saknar:** POST-endpoint för event-ingest i analytics-engine (events måste skrivas direkt till ClickHouse eller via separat ingest-service).
- **Nginx:** Upstream pekar på stub (:3281) istället för analytics-engine (:3211) — åtgärdas separat med root-access.
