# 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",
"duration": 5000000,
"timestamp": "2025-07-29T23:59:21.452419+05:45"
},
{
"name": "Memory Usage",
"status": "healthy",
"message": "Memory usage is within normal limits",
"duration": 2000000,
"timestamp": "2025-07-29T23:59:21.452419+05:45"
},
{
"name": "Queue Health",
"status": "healthy",
"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!
## 📁 Files Created:
1. **admin_server.go** - Main admin server implementation
2. **static/admin/index.html** - Admin dashboard UI
3. **static/admin/css/admin.css** - Dashboard styling
