Explanation

Azure Monitor can collect many data types natively, but some sources require explicitly enabling diagnostics settings before data flows into the platform.

Common mistakes.

A. Windows Event Logs are collected automatically by Azure Monitor through the Log Analytics agent or Azure Monitor Agent without needing to separately enable diagnostics on the resource.
B. Linux Virtual Machine health metrics are collected by default through the Azure Monitor Agent or the dependency agent without requiring additional diagnostic enablement steps.
C. Container workload performance is collected automatically via Azure Monitor for Containers (Container Insights), which is enabled at the AKS cluster level and does not require individual resource diagnostic settings.
