Confuse about diagnostic setting, azure vm insight and data collection rules for azure vm.

Question

Hello everyone, I am currently preparing for AZ-104 and still unable to understand the difference between diagnostic setting, Data collection rule and azure VM insight . All of the above things are doing the same things(as per my R&D).
Thanks in advance.

Thanks for posting your question in the Microsoft Q&A forum.

Diagnostic settings allow you to configure where and how diagnostic data (metrics and logs) from Azure resources is sent. DCRs are part of Azure Monitor and allow you to collect additional data beyond what’s automatically captured. And VM Insights provides monitoring and diagnostics specifically for Azure VMs.

So, Diagnostic Settings: Configure where diagnostic data goes (metrics and logs). Data Collection Rules: Customize data collection beyond defaults. VM Insights: Provides VM-specific monitoring and dashboards.
