1---2name: azure-network-watcher3description: Expert knowledge for Azure Network Watcher development including troubleshooting, decision making, limits & quotas, security, configuration, and integrations & coding patterns. Use when configuring Connection Monitor, NSG/VNet flow logs, packet capture, Traffic Analytics/KQL, or Sentinel integrations, and other Azure Network Watcher related development tasks. Not for Azure Monitor (use azure-monitor), Azure Virtual Network (use azure-virtual-network), Azure Networking (use azure-networking), Azure Virtual Network Manager (use azure-virtual-network-manager).4---5# Azure Network Watcher Skill67This skill provides expert guidance for Azure Network Watcher. Covers troubleshooting, decision making, limits & quotas, security, configuration, and integrations & coding patterns. 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 file1213This skill requires **network access** to fetch documentation content:14- **Preferred**: Use `mcp_microsoftdocs:microsoft_docs_fetch`. Returns Markdown.15- **Fallback**: Use `WebFetch`. Returns Markdown.1617## Category Index1819| Category | Lines | Description |20|----------|-------|-------------|21| Troubleshooting | L30-L40 | Diagnosing and fixing Azure network issues: outbound
