# 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
