  ✅ Alert at 100% ($5)
  ✅ Auto-switch to free tier when exceeded

Monthly budget: $150

   Projected: $135 (within budget)
   
🚨 Daily budget exceeded
   $5.20 / $5.00 spent today
   Auto-switched to free tier
```

### Phát hiện Bất thường Chi phí

```
Dashboard → Settings → Anomaly Detection

✅ Detect unusual spending patterns
✅ Alert on cost spikes (>2× daily average)
✅ Warn on quota exhaustion patterns

Example alert:
⚠️ Cost spike detected
   Today: $12.50 (2.5× daily average)
   Reason: High GLM-4.7 usage (20M tokens)
   Suggestion: Check if primary models quota-exhausted
```

---

## Best Practices

### 1. Theo dõi Quota Hàng ngày

```
Daily routine:
1. Check dashboard quota overview (30 seconds)
2. Review reset times
3. Plan usage around quota availability
```

**Ví dụ:**
```
Morning check:
  ✅ Claude Code: 5h available (fresh reset)
  ✅ Gemini CLI: 1K requests available
  ⚠️ GLM-4.7: 2M tokens left (resets 10AM)
  
Action: Use Claude Code for morning work
```

### 2. Đặt Giới hạn Ngân sách

```
Dashboard → Settings → Budget:
  Daily: $5 (prevents overspending)
  Monthly: $150 (aligns with budget)
```

**Kết quả**: Auto-switch sang free tier khi đạt giới hạn.

### 3. Tối ưu Combo Usage

```
Dashboard → Analytics → Combos:
  Review which models are used most
  Adjust combo order to minimize costs
```

**Ví dụ:**
```
Current: cc/claude-opus → glm/glm-4.7
  80% via Claude (good)
  20% via GLM ($12/month)

Optimized: gc/gemini-3-flash → cc/claude-opus → glm/glm-4.7
  50% via Gemini (free)
  40% via Claude (subscription)
  10% via GLM ($6/month)
  
Savings: $6/month
```

### 4. Theo dõi Thời gian Reset

```
Dashboard → Quota → Reset Schedule:
  Claude Code: 5h rolling + Weekly Monday
  Gemini CLI: Daily 00:00 UTC + Monthly 1st
  GLM-4.7: Daily 10:00 AM Beijing Time
  MiniMax: Rolling 5h window
```

**Chiến lược**: Dùng provider khi quota mới reset.

### 5. Xem Báo cáo Hàng tháng

```
Dashboard → Analytics → Monthly Report:
  Total tokens: 1.5B
  Total cost: $120
  Savings: 97% vs ChatGPT API
  
Insights:
  - 60% usage via subscriptions ($0)
  - 30% via GLM ($90)
  - 10% via free tier ($0)
  
Optimization:
  - Increase Gemini CLI usage (free)
  - Reduce GLM usage (expensive)
```

## Troubleshooting

**Issue: Quota hiển thị 0% nhưng request thất bại**

**Giải pháp:**
1. Kiểm tra kết nối provider (Dashboard → Providers)
2. Xác minh API keys hợp lệ
3. Kiểm tra provider có down không (trang status)
4. Thử kết nối lại OAuth providers

**Issue: Ước tính chi phí sai**

**Giải pháp:**
1. Dashboard → Settings → Pricing
2. Xác minh giá mỗi provider khớp với mức hiện tại
3. Cập nhật giá nếu provider thay đổi
4. Liên hệ support nếu vẫn lệch

**Issue: Thời gian reset không cập nhật**

**Giải pháp:**
1. Refresh dashboard (F5)
2. Kiểm tra thời gian hệ thống đúng
3. Xác minh cài đặt timezone
4. Khởi động lại 9Router nếu vẫn lỗi

**Issue: Không nhận được cảnh báo**

**Giải pháp:**
1. Dashboard → Settings → Alerts
2. Xác minh địa chỉ email đúng
3. Kiểm tra folder spam
4. Test notification (nút Send Test)
