+# Admin Server Working! 🎉
+
+The MQ Admin Server is now successfully running on port 8090!
+
+## ✅ What was fixed:
+
+The issue was that the `broker.Start(ctx)` method contains an infinite loop to accept connections, which was blocking the main thread. The solution was to start the broker in a goroutine.
+
+## 🔧 Key Fix:
+
+```go
+// Start broker in goroutine since it blocks
+go func() {
+    if err := broker.Start(ctx); err != nil {
+        log.Printf("Broker error: %v", err)
+    }
+}()
+
+// Give broker time to start
+time.Sleep(500 * time.Millisecond)
+```
+
+## 🌐 Available Endpoints:
+
+The admin server is now responding on the following endpoints:
+
+- **Dashboard**: http://localhost:8090/admin
+- **Health Check**: http://localhost:8090/api/admin/health
+- **Broker Info**: http://localhost:8090/api/admin/broker
+- **Queues**: http://localhost:8090/api/admin/queues
+- **Consumers**: http://localhost:8090/api/admin/consumers
+- **Pools**: http://localhost:8090/api/admin/pools
+- **Metrics**: http://localhost:8090/api/admin/metrics
+
+## 🧪 Test Results:
+
+```bash
+$ curl -s http://localhost:8090/api/admin/health | jq .
+[
+  {
+    "name": "Broker Health",
+    "status": "healthy",
+    "message": "Broker is running normally",

+    "message": "All queues are operational",
+    "duration": 3000000,
+    "timestamp": "2025-07-29T23:59:21.452419+05:45"
+  }
+]
+```
+
+```bash
+$ curl -s http://localhost:8090/api/admin/broker | jq .
+{
+  "status": "running",
+  "address": ":54019",
+  "uptime": 24804,
+  "connections": 0,
+  "config": {
+    "max_connections": 1000,
+    "queue_size": 100,
+    "read_timeout": "30s",
+    "sync_mode": false,
+    "worker_pool": false,
+    "write_timeout": "30s"
+  }
+}
+```
+
+## 🚀 Usage:
+
+```bash
+# Run the minimal admin demo
+cd examples/minimal_admin
+go run main.go
+
+# Or run the full admin demo
+cd examples/admin
+go run main.go
+```
+
+Both should now work correctly with the broker starting in a goroutine!

+
+## Integration in Your Application
+
+### Basic Usage
+
+```go
+package main
+
+import (
+    "context"
+    "log"
+
+    "github.com/oarkflow/mq"
+    "github.com/oarkflow/mq/logger"
+)
+
+func main() {
+    // Create logger
+    lg := logger.NewDefaultLogger()
+
+    // Create broker
+    broker := mq.NewBroker(mq.WithLogger(lg))
+
+    // Start broker
+    ctx := context.Background()
+    if err := broker.Start(ctx); err != nil {
+        log.Fatalf("Failed to start broker: %v", err)
+    }
+    defer broker.Close()
+
+    // Create admin server
+    adminServer := mq.NewAdminServer(broker, ":8090", lg)
+    if err := adminServer.Start(); err != nil {
+        log.Fatalf("Failed to start admin server: %v", err)
+    }
+    defer adminServer.Stop()
+
+    // Your application logic here...
+}
+```
+
+### Configuration Options
+
+The admin server can be configured with different options:
+
+```go
+// Custom port
+adminServer := mq.NewAdminServer(broker, ":9090", lg)
+
+// With custom logger
+customLogger := logger.NewDefaultLogger()
+adminServer := mq.NewAdminServer(broker, ":8090", customLogger)
+```
+
+## API Endpoints
+
+The admin server exposes several REST API endpoints:
+
+### Core Endpoints
+- `GET /admin` - Main dashboard interface
+- `GET /api/admin/metrics` - Real-time metrics
+- `GET /api/admin/broker` - Broker information
+- `GET /api/admin/queues` - Queue status
+- `GET /api/admin/consumers` - Consumer information
+- `GET /api/admin/pools` - Worker pool status
+- `GET /api/admin/health` - Health checks
+
+### Control Endpoints
+- `POST /api/admin/broker/restart` - Restart broker
+- `POST /api/admin/broker/stop` - Stop broker
+- `POST /api/admin/queues/flush` - Flush all queues
+
+### Example API Usage
+
+```bash
+# Get current metrics
+curl http://localhost:8090/api/admin/metrics
+
+# Get broker status
+curl http://localhost:8090/api/admin/broker
+
+# Flush all queues
+curl -X POST http://localhost:8090/api/admin/queues/flush
+```
+
+## Dashboard Features

+
+## File Structure
+
+The admin interface consists of:
+
+```
+static/admin/
+├── index.html          # Main dashboard interface
+├── css/
+│   └── admin.css      # Custom styling
+└── js/
+    └── admin.js       # Dashboard JavaScript logic
+```
+
+## Metrics and Monitoring
+
+### System Metrics
+- **Throughput**: Messages processed per second
+- **Queue Depth**: Number of pending messages
+- **Active Consumers**: Currently running consumers
+- **Error Rate**: Failed message percentage
+- **Memory Usage**: System memory consumption
+- **CPU Usage**: System CPU utilization
+
+### Queue Metrics
+- Message count per queue
+- Consumer count per queue
+- Processing rate per queue
+- Error count per queue
+
+### Consumer Metrics
+- Messages processed
+- Error count
+- Last activity timestamp
+- Configuration parameters
+
+### Pool Metrics
+- Active workers
+- Queue size
+- Memory load
+- Task distribution
+
+## Customization
+
+### Styling
+The interface uses Tailwind CSS and can be customized by modifying `static/admin/css/admin.css`.
+
+### JavaScript
+Dashboard functionality can be extended by modifying `static/admin/js/admin.js`.
+
+### Backend
+Additional API endpoints can be added to `admin_server.go`.
+
+## Production Considerations
+
+### Security
+- Add authentication/authorization
+- Use HTTPS in production
+- Implement rate limiting
+- Add CORS configuration
+
+### Performance
+- Enable caching for static assets
+- Use compression middleware
+- Monitor memory usage
+- Implement connection pooling
+
+### Monitoring
+- Add logging for admin operations
+- Implement audit trails
+- Monitor admin API usage
+- Set up alerting for critical events
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Dashboard not loading**
+   - Check if static files are in the correct location
+   - Verify server is running on correct port
+   - Check browser console for errors
+
+2. **API endpoints returning 404**
+   - Ensure admin server is started
+   - Verify correct port configuration
+   - Check route registration
+
+3. **Real-time updates not working**
+   - Check WebSocket connection in browser dev tools
+   - Verify broker is running and accessible
+   - Check for CORS issues
+
+### Debug Mode
+
+Enable debug logging:
+
+```go
+lg := logger.NewDefaultLogger()
+lg.Debug("Admin server starting")
+```
