# Crypto Admin Dashboard - Deployment Guide

## Overview

This is a **REAL-DATA-ONLY** Gradio admin dashboard for the Crypto Data Aggregator platform. It provides comprehensive monitoring and management capabilities through a clean web interface.

## Features

### 7 Main Tabs

1. **📊 Status** - System health overview, database stats, quick diagnostics
2. **🔌 Providers** - API provider management with filtering and reload
3. **📈 Market Data** - Live cryptocurrency prices, charts, and market data
4. **🔍 APL Scanner** - Auto Provider Loader for discovering and validating providers
5. **🤖 HF Models** - HuggingFace model status and testing interface
6. **🔧 Diagnostics** - Full system diagnostics with auto-repair capabilities
7. **📋 Logs** - System logs viewer with filtering

### Key Principles

- **NO MOCK DATA**: All data comes from real sources (database, APIs, files)
- **Real-time**: Live updates from actual collectors and services
- **Error Handling**: Graceful degradation with clear error messages
- **HuggingFace Ready**: Designed to run as a Gradio Space

## Installation

### Local Setup

```bash

# 1. Install dependencies

pip install -r requirements.txt



# 2. Ensure database is initialized

python -c "import database; db = database.get_database()"



# 3. Run the app

python app.py

```

The dashboard will be available at: `http://localhost:7860`

### HuggingFace Space Deployment

1. Create a new Space on HuggingFace
2. Choose **Space SDK**: Gradio
3. Upload all necessary files:
   - `app.py` (main entrypoint)
   - `config.py`
   - `database.py`
   - `collectors.py`
   - `ai_models.py`
   - `auto_provider_loader.py`
   - `provider_validator.py`
   - `requirements.txt`
   - `providers_config_extended.json`
   - Backend services (if needed)

4. HuggingFace will automatically detect `app.py` and launch the Gradio app

## Data Sources

### Tab 1: Status
- **Database**: `db.get_database_stats()` - real-time DB metrics
- **Providers**: `providers_config_extended.json` - actual provider count
- **Market**: `db.get_latest_prices(3)` - live top 3 coins

### Tab 2: Providers
- **Source**: `providers_config_extended.json`
- **Categories**: Dynamically extracted from provider configs
- **Operations**: Real file reload, category filtering

### Tab 3: Market Data
- **Prices**: `db.get_latest_prices(100)` - real database records
- **Refresh**: `collectors.collect_price_data()` - live API calls to CoinGecko/CoinCap
- **Charts**: `db.get_price_history(symbol, hours)` - historical data from DB
- **Plotly**: Interactive charts with real price data

### Tab 4: APL Scanner
- **Scan**: `auto_provider_loader.AutoProviderLoader().run()` - actual APL execution
- **Results**: Real validation results from HTTP providers and HF models
- **Report**: Reads actual `PROVIDER_AUTO_DISCOVERY_REPORT.md`

### Tab 5: HF Models
- **Status**: `ai_models.get_model_info()` - real model loading status
- **Test**: `ai_models.analyze_sentiment()`, `ai_models.summarize_text()` - actual HF inference
- **Initialize**: `ai_models.initialize_models()` - loads real transformers models

### Tab 6: Diagnostics
- **Run**: `backend.services.diagnostics_service.DiagnosticsService().run_full_diagnostics()`
- **Checks**: Real dependency checks, network tests, file system validation
- **Auto-fix**: Actually installs packages, creates directories

### Tab 7: Logs
- **Source**: `config.LOG_FILE` - actual log file
- **Filters**: Real-time filtering of ERROR/WARNING/INFO
- **Clear**: Actually clears log file (with backup)

## Testing Checklist

### ✅ Pre-Flight Checks

```bash

# 1. Verify Python version

python --version  # Should be 3.10+



# 2. Install dependencies

pip install -r requirements.txt



# 3. Check database exists

ls -lh data/database/crypto_aggregator.db



# 4. Check config files

ls -lh providers_config_extended.json

ls -lh config.py

```

### ✅ Tab-by-Tab Testing

### ✅ Error Handling Tests

```python

# Test with no data

# 1. Empty database

python -c "import database; db = database.get_database(); import os; os.remove(str(db.db_path))"



# 2. Run app - should show "No data available" messages, not crash



# Test with missing config

# 1. Rename providers config

mv providers_config_extended.json providers_config_extended.json.bak



# 2. Run app - should show error messages, not crash



# Test with no internet

# 1. Disconnect network

# 2. Click "Refresh Prices" - should show connection errors, not crash

```

## Configuration

### Environment Variables

Optional environment variables for enhanced functionality:

```bash

# HuggingFace API token (for model access)

export HF_TOKEN="your_hf_token_here"



# API keys (optional)

export CMC_API_KEY="your_coinmarketcap_key"

export ETHERSCAN_KEY="your_etherscan_key"

```

### Config.py Settings

Key settings in `config.py`:

```python

LOG_LEVEL = "INFO"  # DEBUG, INFO, WARNING, ERROR

AUTO_REFRESH_INTERVAL = 30  # seconds

GRADIO_SERVER_NAME = "0.0.0.0"

GRADIO_SERVER_PORT = 7860

```

## Troubleshooting

### Issue: "gradio not installed"
```bash

pip install gradio

```

### Issue: "No market data available"
```bash

# Collect initial data

python -c "import collectors; collectors.collect_price_data()"

```

### Issue: "Plotly not available"
```bash

pip install plotly

# Charts will work after restart

```

### Issue: "Transformers not available"
```bash

pip install transformers torch

# HF model features will work after restart

```

### Issue: "Log file not found"
```bash

# Ensure logs directory exists

mkdir -p logs

# Run any collector to create log

python -c "import collectors; collectors.collect_price_data()"

```

## Performance Notes

- **Initial Load**: First load may be slow as models initialize
- **APL Scan**: Can take 30-60 seconds to validate all providers
- **Diagnostics**: Full scan takes ~5-10 seconds
- **Charts**: Rendering large datasets may take a few seconds

## Security Notes

- **Database Queries**: Only SELECT queries allowed in DB Explorer
- **Log Clearing**: Creates backup before clearing
- **Auto-Fix**: Only installs packages and creates directories
- **No Shell Access**: No direct shell command execution

## Development

### Adding New Tabs

```python

with gr.Tab("🆕 New Tab"):

    gr.Markdown("### New Feature")

    

    # Your components here

    output = gr.Markdown()

    

    def new_function():

        # MUST use real data only

        return "Real data result"

    

    demo.load(

        fn=new_function,

        outputs=output

    )

```

### Adding New Data Sources

1. Add function to fetch real data (no mock data!)
2. Wire function to Gradio component
3. Add error handling
4. Test with missing/unavailable data
