```

## What it does

- Cubre Azure Event Hubs y Azure Service Bus a través de las herramientas MCP `mcp_azure_mcp_eventhubs` y `mcp_azure_mcp_servicebus`.
- Está orientado a diagnosticar problemas de conexión del SDK, de autenticación y de procesamiento de mensajes.

## Use it when

- Hay que diagnosticar errores del SDK de mensajería, fallos de conexión AMQP, pérdida del lock de un mensaje o mensajes en dead letter.

## What triggers it

- "falla la conexión AMQP a Service Bus"
- "mensajes atascados en dead letter"
- "error del SDK de Event Hubs"

## Before you install

- Depende de las herramientas MCP de Azure para Event Hubs y Service Bus.

# Azure Messaging SDK Troubleshooting

## Quick Reference

| Property | Value |
|----------|-------|
| **Services** | Azure Event Hubs, Azure Service Bus |
| **MCP Tools** | `mcp_azure_mcp_eventhubs`, `mcp_azure_mcp_servicebus` |
| **Best For** | Diagnosing SDK connection, auth, and message processing issues |

## When to Use This Skill

- SDK connection failures, auth errors, or AMQP link errors
- Idle timeout, connection inactivity, or slow reconnection after disconnect
- AMQP link detach or detach-forced errors
- Message lock lost, message lock expired, lock renewal failures, or batch lock timeouts
- Session lock lost, session lock expired, or session receiver errors
- Event processor or message handler stops processing
- Duplicate events or checkpoint offset resets
- SDK configuration questions (retry, prefetch, batch size, receive batch behavior)

## MCP Tools

| Tool | Command | Use |
|------|---------|-----|
| `mcp_azure_mcp_eventhubs` | Namespace/hub ops | List namespaces, hubs, consumer groups |
| `mcp_azure_mcp_servicebus` | Queue/topic ops | List namespaces, queues, topics, subscriptions |
| `mcp_azure_mcp_monitor` | `logs_query` | Query diagnostic logs with KQL |
| `mcp_azure_mcp_resourcehealth` | `get` | Check service health status |
| `mcp_azure_mcp_documentation` | Doc search | Search Microsoft Learn for troubleshooting docs |

## Diagnosis Workflow

1. **Identify the SDK and version** — Check the prompt for SDK and version clues; if not stated, proceed with diagnosis and ask later if needed
2. **Check resource health** — Use `mcp_azure_mcp_resourcehealth` to verify the namespace is healthy
3. **Review the error message** — Match against language-specific troubleshooting guide
4. **Look up documentation** — Use `mcp_azure_mcp_documentation` to search Microsoft Learn for the error or topic
5. **Check configuration** — Verify connection string, entity name, consumer group
6. **Recommend fix** — Apply remediation, citing documentation found


## Troubleshooting Guides

Connectivity, SDK, and auth troubleshooting guides are located in the azure-diagnostics skill under `troubleshooting/messaging/`.
