Azure Network Watcher Skill

This 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.

How to Use This Skill

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 file

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

This skill requires network access to fetch documentation content:

• Preferred: Use mcp_microsoftdocs:microsoft_docs_fetch with query string from=learn-agent-skill. Returns Markdown.
• Fallback: Use fetch_webpage with query string from=learn-agent-skill&accept=text/markdown. Returns Markdown.

Category Index

Category	Lines	Description
Troubleshooting	L34-L44	Diagnosing and fixing Azure network issues: outbound connectivity, NSG/admin rules, and VPN gateway/on-premises connectivity, including automation and CLI/PowerShell-based troubleshooting.
Decision Making	L45-L51	Guidance for migrating network monitoring: moving from classic Connection Monitor and Network Performance Monitor tests, and switching NSG flow logs to VNet flow logs.
Limits & Quotas	L52-L56	How to configure and run Network Watcher packet capture, storage and filtering options, and the key limits/quotas (size, duration, concurrency) that apply to captures
Security	L57-L64	Securing Network Watcher: RBAC setup, hardening deployments and data access, Zero Trust segmentation with Traffic Analytics, and protecting VNet flow logs using managed identities.
Configuration	L65-L79	Configuring and governing Network Watcher logging: AMA for Connection Monitor, NSG/VNet flow logs setup, schemas, filtering, templates (Bicep/ARM), and Azure Policy enforcement.
Integrations & Coding Patterns	L80-L85	Using Network Watcher data in tools and code: parsing NSG flow logs with PowerShell, visualizing in Power BI, triggering packet capture from Functions, querying Traffic Analytics with KQL, and integrating with Sentinel.
