Covers troubleshooting, best practices, decision making, architecture & design patterns, limits & quotas, security, configuration, integrations & coding patterns, and deployment. It combines local quick-reference content with remote documentation fetching capabilities.89## How to Use This Skill1011> **IMPORTANT for Agent**: Use the **Category Index** below to locate relevant sections. For categories with line ranges (e.g., `L35-L120`), use `read_file` with the specified lines. For categories with file links (e.g., `[security.md](security.md)`), use `read_file` on the linked reference file1213> **IMPORTANT for Agent**: If `metadata.generated_at` is more than 3 months old, suggest the user pull the latest version from the repository. If `mcp_microsoftdocs` tools are not available, suggest the user install it: [Installation Guide](https://github.com/MicrosoftDocs/mcp/blob/main/README.md)1415This skill requires **network access** to fetch documentation content:16- **Preferred**: Use `mcp_microsoftdocs:microsoft_docs_fetch` with query string `from=learn-agent-skill`. Returns Markdown.17- **Fallback**: Use `fetch_webpage` with query string `from=learn-agent-skill&accept=text/markdown`. Returns Markdown.1819## Category Index2021| Category | Lines | Description |22|----------|-------|-------------|23| Troubleshooting | L37-L49 | Diagnosing and fixing Event Hubs runtime issues: Kafka/AMQP errors, .NET/legacy exceptions, ARM failures, auth problems, checkpoint store, and connectivity (transient/permanent). |24| Best Practices | L50-L55 | Guidance on routing events between AMQP, Kafka, and HTTPS, and on designing/scaling Event Hubs with partitions and throughput units for performance and capacity. |25| Decision Making | L56-L61 | Guidance on choosing the right Event Hubs tier and planning migrations from Apache Kafka, including feature, cost, and compatibility considerations. |26| Architecture & Design Patterns | L62-L69 | Patterns and guidance for Event Hubs reliability: availability/consistency design, geo-disaster recovery, and building/operating replication tasks (often with Azure Functions). |27| Limits & Quotas | L70-L78 | Event Hubs capacity, quotas, and throughput limits, plus auto-inflate, geo-disaster recovery, and governance via application groups and FAQs on behavior and scaling. |28| Security | L79-L105 | Security, auth, and compliance for Event Hubs: Entra ID, SAS, RBAC, managed identities, encryption, TLS, network isolation (VNet, Private Link, NSP, firewalls), and Azure Policy governance. |29| Configuration | L106-L118 | Configuring Event Hubs behavior: partitions, retention, compaction, scaling, replication, metrics/logs, governance (application groups), and Premium processing units. |30| Integrations & Coding Patterns | L119-L136 | Patterns and code for integrating Event Hubs with .NET, Kafka (clients, Streams, Connect, Debezium), Flink, Spark, Akka, schema/JSON registry, and adding metadata or managing hubs programmatically |31| Deployment | L137-L143 | Guides for deploying Event Hubs with Kafka mirroring (MirrorMaker 1/2), setting up geo-replication, and running/local-testing Event Hubs apps using the emulator. |3233### Troubleshooting34| Topic | URL |35|-------|-----|36| Resolve common Kafka compatibility issues in Event Hubs |
