# Story 5.3: Admin - System Health Dashboard
Status: done
## Story
En tant qu'**Admin**,
Je veux **voir les métriques de santé système en temps réel**,
de sorte que **je puisse surveiller la plateforme et réagir rapidement aux problèmes**.
## Acceptance Criteria
1. **System Health Card**: Affiche le statut global du système (healthy/unhealthy) avec indicateur animé
2. **Disk Space Card**: Affiche l'utilisation disque en pourcentage avec barre de progression
3. **Temporary Files Card**: Affiche le nombre de fichiers orphelins avec bouton de purge
4. **Provider Status Panel**: Affiche le statut de chaque provider (Google, DeepL, Ollama, OpenAI) avec latence
5. **Auto Refresh**: Les métriques se rafraîchissent automatiquement toutes les 30 secondes
6. **Manual Refresh**: Bouton pour rafraîchir manuellement les données
7. **Purge Action**: Le bouton "Purge" déclenche `/api/v1/admin/cleanup/trigger` et affiche le résultat
8. **Loading States**: États de chargement pendant les appels API
9. **Error Handling**: Gestion gracieuse des erreurs API avec message utilisateur
10. **Responsive**: S'affiche correctement sur desktop et mobile

## Dev Notes
### 🏗️ Stack Technique
| Technologie | Version |
|-------------|---------|
| Next.js | 16.0.6 (App Router) |
| React | 19.2.0 |
| TanStack Query | v5 |
| Tailwind CSS | configuré |
| shadcn/ui | Card, Button, Progress, Badge, Tooltip |
| Lucide React | HeartPulse, HardDrive, FileWarning, Trash2, Loader2, RefreshCw |
### 📁 Structure Cible (Colocation Pattern)
```
frontend/src/app/admin/
├── layout.tsx # Layout existant avec sidebar/header
├── page.tsx # ⭐ Dashboard admin principal (modifier)
├── SystemHealthCards.tsx # ⭐ Nouveau: Cards santé système
├── ProviderStatus.tsx # ⭐ Nouveau: Panel statut providers
├── useAdminDashboard.ts # ⭐ Nouveau: Hook TanStack Query
├── useCleanup.ts # ⭐ Nouveau: Hook pour purge
├── types.ts # ⭐ Nouveau: TypeScript interfaces
├── AdminSidebar.tsx # Existant (Story 5.2)
├── AdminHeader.tsx # Existant (Story 5.2)
├── login/ # Existant
├── users/ # Placeholder (Story 5.4)
├── system/ # Placeholder (Story 5.6)
└── logs/ # Placeholder (Story 5.7)
```
**⚠️ Règle absolue (architecture.md):**
```
🚨 FICHIERS SPÉCIAUX: page.tsx, layout.tsx → TOUJOURS minuscules
🚨 COLOCATION: Components/hooks/types dans le dossier de leur page
```

### 🎨 Patterns UI à Réutiliser
**SystemHealthCards.tsx** - depuis `office-translator-landing-page/components/admin-system-health.tsx`:
```tsx
// Structure à adapter
<Card className="py-0">
<CardContent className="flex items-center gap-3 px-4 py-3">
<div className="flex size-9 shrink-0 items-center justify-center rounded-lg bg-[oklch(0.59_0.16_145/0.1)]">
<HeartPulse className="size-4 text-[oklch(0.59_0.16_145)]" />
</div>
<div className="flex flex-1 flex-col gap-0.5">
<span className="text-[10px] font-medium uppercase tracking-wider text-muted-foreground">
Server Health
</span>
<div className="flex items-center gap-1.5">
<span className="relative flex size-2">
<span className="absolute inline-flex size-full animate-ping rounded-full bg-[oklch(0.59_0.16_145)] opacity-75" />
<span className="relative inline-flex size-2 rounded-full bg-[oklch(0.59_0.16_145)]" />
</span>
<span className="text-sm font-semibold text-foreground">All Systems Operational</span>
</div>
</div>
</CardContent>
</Card>
```
**ProviderStatus.tsx** - depuis `office-translator-landing-page/components/admin-provider-status.tsx`:
```tsx
// Structure à adapter
<div className="flex flex-wrap items-center gap-2">
{providers.map((provider) => (
<Tooltip key={provider.name}>
<TooltipTrigger asChild>
<Badge variant="outline" className="gap-1.5 px-2.5 py-1">
<span className="size-1.5 rounded-full bg-green-500" />
{provider.name}
</Badge>
</TooltipTrigger>
<TooltipContent>
<span>Latency: {provider.latency}</span>
</TooltipContent>
</Tooltip>
))}
</div>
```
### 🔄 TanStack Query Pattern
```tsx
// useAdminDashboard.ts
import { useQuery } from '@tanstack/react-query'
export function useAdminDashboard() {
return useQuery({
queryKey: ['admin', 'dashboard'],
queryFn: async () => {
const token = localStorage.getItem('adminToken')
const res = await fetch(`${process.env.NEXT_PUBLIC_API_URL}/api/v1/admin/dashboard`, {
headers: { Authorization: `Bearer ${token}` }
})
if (!res.ok) throw new Error('Failed to fetch dashboard')
return res.json()
},
refetchInterval: 30000, // 30 seconds
staleTime: 10000,
})
}
```
### ⚠️ Points d'Attention Critiques
1. **Authentification**: Tous les appels API doivent inclure le header `Authorization: Bearer {adminToken}`. Le token est stocké dans le Zustand store: `useTranslationStore().settings.adminToken`.
2. **Gestion du token admin**: Utiliser le même pattern que dans `useAdminLogin.ts` pour récupérer le token depuis le store.
3. **Provider Status Mapping**: Le backend retourne `available: true/false`. Mapper vers les états visuels:
- `available: true` → "online" (vert)
- `available: false` → "offline" (rouge)
- Pas de réponse → "degraded" (jaune)
4. **Zustand Store Access**: Le token est dans `useTranslationStore().settings.adminToken`. Vérifier que le store est accessible.
5. **Error Handling**: Utiliser `toast` de shadcn/ui pour afficher les erreurs de manière non-intrusive.
6. **Composants shadcn/ui**: Vérifier que Progress et Tooltip sont installés. Sinon:
```bash
npx shadcn@latest add progress tooltip
```
7. **Couleurs OKLCH**: Le design utilise des couleurs OKLCH modernes. Si le projet ne les supporte pas, utiliser des classes Tailwind standard.
### 📋 Checklist de Validation Avant Dev
- [x] `useAdminDashboard.ts` hook créé avec TanStack Query
- [x] `useCleanup.ts` hook créé pour la purge
- [x] `types.ts` créé avec interfaces TypeScript
- [x] Composants shadcn/ui disponibles (Card, Button, Progress, Badge, Tooltip)
- [x] Backend `/api/v1/admin/dashboard` retourne les données attendues
- [x] Backend `/api/v1/admin/cleanup/trigger` fonctionne
### 🚀 Integration Steps
1. **Créer types.ts** avec les interfaces TypeScript
2. **Créer useAdminDashboard.ts** avec TanStack Query
3. **Créer useCleanup.ts** pour la purge
4. **Créer SystemHealthCards.tsx** en adaptant le design
5. **Créer ProviderStatus.tsx** en adaptant le design
6. **Modifier page.tsx** pour intégrer les composants
7. **Tester** avec le backend actif
