Summary:
The documentation is heavily focused on Windows environments, specifically Windows DNS servers. All examples, prerequisites, and configuration steps are tailored exclusively to Windows Server, with no mention of Linux-based DNS servers or how to achieve similar functionality on Linux. Windows tools, logs, and event types are referenced throughout, and there are no Linux equivalents or cross-platform guidance provided.
Recommendations:
- Add equivalent instructions and examples for collecting and filtering DNS logs from Linux-based DNS servers (e.g., BIND, Unbound, dnsmasq).
- Include prerequisites and setup steps for Linux environments, such as supported distributions, required packages, and log file locations.
- Provide API and portal configuration examples that reference Linux data sources and illustrate how to normalize and ingest Linux DNS logs.
- Reference Linux tools and logging patterns (e.g., systemd-journald, syslog, logrotate) alongside Windows event logs.
- 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.
