# 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
|
||||

|
||||
]
|
||||
```
|
||||
|
||||
```bash

|
||||
"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!

## Recommended Implementation Priority
|
||||
|
||||
1. **High Priority** (Immediate)
|
||||
- Enhanced monitoring and metrics
|
||||
- Persistent storage integration
|
||||
- Security hardening
|
||||
- API management interface
|
||||
|
||||
2. **Medium Priority** (Next Sprint)
|
||||
- Distributed processing capabilities
|
||||
- Advanced retry and error handling
|
||||
- Performance optimization features
|
||||
- Comprehensive testing suite
|
||||
|
||||
3. **Lower Priority** (Future Releases)
|
||||
- Advanced analytics and ML integration
|
||||
- Multi-tenancy support
|
||||
- Plugin ecosystem
|
||||
- Advanced clustering features
|
||||
|
||||
## Performance Benchmarks to Establish
|
||||
|
||||
- Tasks processed per second under various loads
|
||||
- Memory usage patterns and efficiency
|
||||
- Latency percentiles (P50, P95, P99)
|
||||
- Worker scaling responsiveness
|
||||
- Error recovery time
|
||||
- Circuit breaker effectiveness
|
||||
|
||||
The enhanced worker pool is now production-ready with robust error handling, proper resource management, and comprehensive monitoring capabilities. The suggested features will further enhance its capabilities for enterprise-scale deployments.

# MQ Admin Dashboard
|
||||
|
||||
The MQ Admin Dashboard provides a comprehensive web-based interface for managing and monitoring your MQ broker, queues, consumers, and worker pools. It offers real-time metrics, control capabilities, and health monitoring similar to RabbitMQ's management interface.
|
||||
|
||||

|
||||
|
||||
### 🌟 **Comprehensive Dashboard**
|
||||
- **Real-time Monitoring**: Live charts showing throughput, queue depth, and system metrics
|
||||
- **Broker Management**: Monitor broker status, uptime, and configuration
|
||||
- **Queue Management**: View queue depths, consumer counts, and flush capabilities
|
||||
- **Consumer Control**: Monitor consumer status, pause/resume operations, and performance metrics
|
||||
- **Worker Pool Management**: Track pool status, worker counts, and memory usage
|
||||
- **Health Checks**: System health monitoring with detailed status reports
|
||||
|
||||
### 📊 **Real-time Visualizations**
|
||||
- Interactive charts powered by Chart.js
|
||||
- Live WebSocket updates for real-time data
|
||||
- Throughput history and trend analysis
|
||||
- System resource monitoring (CPU, Memory, Goroutines)
|
||||
|
||||
### 🎛️ **Management Controls**
|
||||
- Pause/Resume consumers
|
||||
- Adjust worker pool settings
|
||||
- Flush queues
|
||||

|
||||
|
||||
## 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)
|
||||
```
|
||||
|
||||

## 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")
|
||||
```
