You will be using Azure Monitor to collect data about your Azure infrastructure. Can you identify the type of data collection that requires you to enable diagnostics?

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.

Linux Virtual Machine health metrics are collected by default through the Azure Monitor Agent or the dependency agent without requiring additional diagnostic enablement steps.

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.

Usage data for Web Applications (Azure App Service) requires enabling Application Insights or diagnostic settings on the App Service resource before Azure Monitor can collect metrics and logs such as request rates, failure rates, and response times. Without enabling diagnostics, this telemetry is not automatically forwarded to Azure Monitor.
