 - TensorFlow.js export is intentionally done with the `tensorflowjs_converter` CLI rather than from Python to avoid protobuf/runtime conflicts documented in the README.
 - `apps/ml-service/` is a Rust/Axum service that loads the ONNX model and serves HTTP endpoints for health checks, metadata, and image classification predictions. It uses ONNX Runtime for cross-platform inference performance.
 
+## Telemetry architecture
+
+The repository includes a full Prometheus → ClickHouse metric pipeline as a git submodule at `telemetry/`. Each ZeaVis Edu service exposes a `GET /metrics` endpoint:
+
+- **Web app** (`apps/web`): In dev mode, a Vite plugin serves client-side session metrics (page views, Web Vitals). In production, nginx proxies `/metrics` to the API service. Source: `apps/web/src/lib/telemetry.ts`, `apps/web/vite-plugin-metrics.ts`.
+- **API** (`apps/api`): Uses `prom-client` for Node.js default metrics plus custom HTTP, auth, classification, and diagnosis counters/histograms. Source: `apps/api/src/lib/telemetry.ts`, exposed via `apps/api/src/routes/metrics.ts`.
+- **ML service** (`apps/ml-service`): Uses the `prometheus` Rust crate for HTTP metrics, prediction counts, and model load status. Source: `apps/ml-service/src/telemetry.rs`.
+
+All three share the `zeavis_` metric prefix and are scraped by the Telemetry Prometheus instance via `file_sd_configs` (see `telemetry/prometheus/targets/zeavis-edu.json`).
+
+**IMPORTANT — Production architecture:** ZeaVis Edu apps and the Telemetry stack run on **separate VPS instances** connected via **Tailscale** (mesh VPN). Prometheus scrapes the API and ML service through their **Tailscale IPs** (e.g. `100.x.x.a:3000`), not via Docker hostnames. The target file `telemetry/prometheus/targets/zeavis-edu.json` has `__CHANGE_ME__` placeholders — before deploying, replace with the actual Tailscale IPs of the app VPS.
+
+The telemetry stack is managed from the project root via `make telemetry-*` targets (see `Makefile`). The Docker Compose files in `telemetry/deploy/` define 6 services (Prometheus, Metric Ingester, Vector, ClickHouse, Query Proxy, Telemetry UI).
+
+For **local single-host dev**, Prometheus can reach app services via a shared Docker network (`app-shared-net`). Use `make telemetry-up-local` for this mode — it includes the `docker-compose.telemetry.yml` override.

+## Prometheus Auto‑Discovery (Telemetry Stack)
+
+The Telemetry submodule includes a Prometheus instance that uses
+`file_sd_configs` to discover targets. Place a target file under
+`telemetry/prometheus/targets/` with content such as:
+
+```json
+[
+  {
+    "targets": ["100.x.x.a:3000"],
+    "labels": { "service": "zeavis-api", "component": "backend", "env": "production" }
+  },
+  {
+    "targets": ["100.x.x.b:8000"],
+    "labels": { "service": "zeavis-ml", "component": "inference", "env": "production" }
+  }
+]
+```
+
+> ⚠️ **Cross-VPS:** Gunakan **IP Tailscale** (bukan Docker hostname) karena
+> Prometheus dan ZeaVis Edu berjalan di VPS berbeda. Pastikan port service
+> (`:3000`, `:8000`) terekspos di `0.0.0.0` atau diizinkan oleh aturan
+> `iptables`/`ufw` untuk interface Tailscale (`tailscale0`/`100.x.x.x/10`).
+
+The Prometheus config (in `telemetry/prometheus/prometheus.yml`) will
+automatically pick up new files within its 15‑second scrape interval —
+no restart required.

+## Telemetry Stack
+
+Proyek ini menyertakan pipeline telemetry metric sebagai git submodule di `telemetry/`. Pipeline mengalirkan metrik dari seluruh service ZeaVis Edu ke ClickHouse untuk analisis dan visualisasi jangka panjang.
+
+### Arsitektur (Production)
+
+Di production, aplikasi dan telemetry berjalan di **VPS terpisah** dan terhubung via **Tailscale** (mesh VPN). Prometheus di VPS telemetry melakukan scrape ke service ZeaVis Edu melalui IP Tailscale masing-masing.
+
+```mermaid
+flowchart LR
+    subgraph VPS1["VPS — ZeaVis Edu (App)"]
+        W[Web / React<br/>api-zeavisedu.asepharyana.id]

+    P -->|remote_write| MI
+    MI --> V
+    V --> CH
+    QP --> CH
+    TUI --> QP
+```
+
+Setiap service ZeaVis Edu mengekspos endpoint `/metrics` dalam format Prometheus text:
+
+| Service               | Endpoint           | Port (lokal) |
+|-----------------------|--------------------|--------------|
+| Web (Vite dev)        | `GET /metrics`     | 5173         |
+| API (Elysia)          | `GET /metrics`     | 3000         |
+| ML Service (Axum)     | `GET /metrics`     | 8000         |
+
+Prometheus di VPS telemetry melakukan **scrape langsung** ke API dan ML service melalui IP Tailscale mereka, bukan melalui domain publik. Konfigurasi target ada di `telemetry/prometheus/targets/zeavis-edu.json` — isi dengan IP Tailscale dari service yang dituju.
+
+Lihat [`METRICS.md`](./METRICS.md) untuk daftar lengkap metrik yang diekspos.
+
+### Service Telemetry
+
+| # | Service | Peran | Port |
+|---|---------|------|------|
+| 1 | **Prometheus** | Metric scraping & remote_write | 9090 |
+| 2 | **Metric Ingester** | Enrichment, filtering, aggregation | 9091 |
+| 3 | **Vector** | Buffering, backpressure, retry | 9001 |
+| 4 | **ClickHouse** | Columnar analytical storage | 8123 / 9000 |
+| 5 | **Query Proxy** | Read-only SQL proxy, tenant isolation | 9092 |
+| 6 | **Telemetry UI** | Vue 3 metrics dashboard | 8181 |
+
+### Arsitektur (Local Dev)
+
+Untuk development lokal di satu mesin, telemetry dan app bisa jalan bareng di satu Docker host. Prometheus bisa scrape service lewat Docker network yang sama.
+
+```bash
+# Setup network
+docker network create app-shared-net
+
+# Build & start telemetry (dengan network sharing)
+make telemetry-up-local
+```
+
+### Menjalankan Telemetry Stack
+
+Semua operasi telemetry dijalankan dari **root proyek** melalui Makefile:
+
+```bash
+# Build komponen telemetry (metric-ingester + telemetry-ui)
+make telemetry-build
+
+# Start semua service telemetry (mode produksi, via Tailscale)
+make telemetry-up
+
+# Start semua service telemetry (mode lokal — port langsung terbuka)
+make telemetry-up-local
+
+# Cek status kesehatan semua service
+make telemetry-status
+
+# Lihat log (semua service, atau filter dengan s=)
+make telemetry-logs
+make telemetry-logs s=metric-ingester
+
+# Restart service tertentu
+make telemetry-restart s=prometheus
+
+# Kirim test metric
+make telemetry-test-metric
+
+# Stop semua service
+make telemetry-down
+```
+
+Untuk development lokal:
+
+```bash
+# Setup network jika belum ada
+docker network create telemetry-net
+docker network create app-shared-net
+
+# Build & start
+make telemetry-build
+make telemetry-up-local
+
+# Buka dashboard di http://localhost:8181
+```
+
+### Prometheus Auto-Discovery
+
+Prometheus menggunakan `file_sd_configs` untuk menemukan target secara dinamis. Cukup letakkan file JSON di `telemetry/prometheus/targets/` dan Prometheus akan otomatis mendeteksinya dalam 15 detik — tanpa restart.
+
+File template sudah tersedia di [`telemetry/prometheus/targets/zeavis-edu.json`](telemetry/prometheus/targets/zeavis-edu.json). **Sebelum production, isi `__CHANGE_ME__` dengan IP Tailscale masing-masing service:**
+
+```json
+[
+  { "targets": ["100.x.x.a:3000"], "labels": { "service": "zeavis-api", "component": "backend", "env": "production" } },
+  { "targets": ["100.x.x.a:8000"],  "labels": { "service": "zeavis-ml", "component": "inference", "env": "production" } }
+]
+```
+
+> **Catatan:** Aplikasi ZeaVis Edu mengekspose port Docker-nya (`:3000`, `:8000`) langsung ke host via `docker-compose.yml`. Pastikan port-port tersebut terbuka di network Tailscale (biasanya iptables Tailscale mengizinkan koneksi ke port localhost).
+
+### Environment Variables Telemetry
+
+| Variable | Default | Deskripsi |
+|----------|---------|-----------|
+| `CLICKHOUSE_USER` | `telemetry` | User ClickHouse |
+| `CLICKHOUSE_PASSWORD` | `telemetry` | Password ClickHouse |

+
+### VPS Setup
+
+#### 1. App VPS (imrnes — 100.108.1.124)
+
+```bash
+# Create Docker network
+docker network create app-shared-net
+docker network create telemetry-net
+
+# ZeaVis Edu apps deploy automatically via GitHub Actions
+```
+
+#### 2. Telemetry VPS (orange — 100.96.248.86)
+
+Deploy via GitHub Actions workflow `.github/workflows/telemetry-ci-cd.yml`.
+
+Atau manual:
+```bash
+ssh mytheclipse@100.96.248.86
+mkdir -p /opt/telemetry
+# ... sync files from telemetry/ directory ...
+cd /opt/telemetry
+docker compose up -d
+bash clickhouse/init.sh
+```
+
+## Port yang dibuka
+
+### App VPS (imrnes)
+| Port | Service | Akses |
+|------|---------|-------|
+| 80/443 | Web (via Traefik/Coolify) | Public |
+| 3000 | API metrics | Tailscale-only |
+| 8000 | ML service metrics | Tailscale-only |
+| 9100 | Node Exporter | Tailscale-only |
+
+### Telemetry VPS (orange)
+| Port | Service | Akses |
+|------|---------|-------|
+| 80/443 | Telemetry UI (via Coolify Traefik) | Public |
+| 8181 | Telemetry UI (direct) | Tailscale-only |
+| 9090 | Prometheus | Tailscale-only |
+| 9091 | Metric Ingester | Tailscale-only |
+| 9001 | Vector HTTP source | Tailscale-only |
+| 8123 | ClickHouse HTTP | Tailscale-only |
+| 9000 | ClickHouse Native | Tailscale-only |
+
+## Metrics Flow
+
+1. **App services** expose `/metrics` pada port masing-masing
+2. **Prometheus** di orange VPS scrape via Tailscale IP (`100.108.1.124:PORT`)
+3. **Prometheus** forward ke **Metric Ingester** via `remote_write`
+4. **Metric Ingester** enrich → filter → forward ke **Vector**
+5. **Vector** buffer → write ke **ClickHouse**
+6. **Telemetry UI** query via **Query Proxy** → **ClickHouse**
+
+## Useful Commands
+
+```bash
+# Telemetry stack status
+make telemetry-status
+
+# View telemetry logs
+make telemetry-logs s=prometheus
+
+# Send test metric
+make telemetry-test-metric
+
+# Restart a service
+make telemetry-restart s=vector
+```
