- Current task description
- Progress bar (0-100%)
Pattern 5 - Approval Requests:
- Approval type
- Requesting agent
- Context information
- Approve/Reject buttons
Pattern 6 - Quality Metrics:
- Workflow/stage/tier breakdown
- Quality score (0-100%)
- Sample count
- Trend indicator (📈📉➡️)
Pattern 2 - Recent Signals:
- Signal type
- Source → Target route
- Relative timestamp
Pattern 4 - Event Stream:
- Event type
- Source agent
- Timestamp
- Scrollable feed
Pattern 6 - Underperforming Stages:
- Workflow/stage identification
- Average quality
- Quality range

Backend:
- Simple Server: Python http.server (stdlib)
- FastAPI Server: FastAPI + uvicorn (optional)
Frontend:
- Vanilla JavaScript (no frameworks)
- CSS Grid & Flexbox
- Auto-refresh via polling
Data Source:
- Redis 5.0+ (optional - graceful degradation)
- Empathy telemetry modules
Required:
- Python 3.10+
- Empathy Framework telemetry modules
Optional:
- Redis 5.0+ (for data persistence)
- FastAPI + uvicorn (for advanced features)
Simple Server:
- Page load: <2s
- API response: <50ms per endpoint
- Memory: ~30MB
- CPU: <5% idle, <10% during refresh
Auto-Refresh:
- Interval: 5 seconds
- Overhead: <100ms
- Network: ~10KB per refresh
- ✅ Chrome/Edge (latest)
- ✅ Firefox (latest)
- ✅ Safari (latest)
- ✅ Mobile browsers (responsive design)
For Production:
- Add HTTP Basic Auth or OAuth
- Deploy behind HTTPS proxy
- Restrict network access (VPN/firewall)
- Rate limit approval endpoints
Example Basic Auth:
from functools import wraps
def require_auth(handler):
@wraps(handler)
def wrapper(self):
auth = self.headers.get('Authorization')
if not auth or auth != 'Bearer secret-token':
self.send_error(401, "Unauthorized")
return
return handler(self)

}Planned features (not yet implemented):
- Full WebSocket real-time push (currently polling)
- Authentication & user management
- Historical charts/graphs
- Email/Slack notifications
- Export reports (PDF/CSV)
- Custom dashboards
- Dark/light theme toggle
- Multi-workspace support
- Agent logs viewer
The dashboard can be tested with the demo script:
# 1. Start Redis
redis-server
# 2. Run demo
python examples/dashboard_demo.py
# 3. Open browser
# http://localhost:8000
# 4. Verify all panels show dataExpected Results:
- 5 active agents in "Active Agents" panel
- 10 signals in "Recent Signals" panel
- 15 events in "Event Stream" panel
- 2 pending approvals in "Approval Requests" panel
- Quality metrics in "Quality Metrics" panel
- Some underperforming stages (if quality < 70%)
Issue: Dashboard shows empty panels
Solution: Generate test data with dashboard_demo.py or create real agents
Issue: "System Degraded" status
Solution: Start Redis: redis-server
Issue: Approval buttons don't work
Solution: Check browser console (F12) for errors, verify Redis connection
Issue: "Connection Failed"
Solution: Ensure dashboard server is running on port 8000
