Summary
The documentation is heavily focused on Windows DNS servers, with all instructions, examples, and prerequisites exclusively referencing Windows Server environments. There are no examples, guidance, or mentions of Linux-based DNS servers or their log collection. Windows tools and patterns (such as enabling Windows DNS analytical logs, using Windows-specific event fields, and configuring Windows-specific connectors) are referenced throughout, with no Linux parity or alternatives provided.
Recommendations
- Add equivalent instructions and examples for collecting and filtering DNS logs from Linux-based DNS servers (e.g., BIND, Unbound, dnsmasq).
- Document how to use the AMA connector (or other Azure Monitor mechanisms) with Linux DNS servers, including prerequisites, configuration steps, and supported log formats.
- Provide API and portal configuration examples for Linux DNS log sources, ensuring field mappings and normalization guidance are included.
- Clarify in the introduction and prerequisites whether Linux DNS servers are supported, and if not, provide guidance or links to alternative solutions for Linux environments.
- Include references to Linux tools and patterns (such as syslog, journald, or native DNS log files) and how they can be integrated into Microsoft Sentinel.
