Which Azure service should you use to collect events from multiple resources into a centralized repository?

Correlate events=Azure Log Analytics

Collect events= Azure Event Hubs

Log Analytics ingests a wide range of event logs, which are available for review and analysis. The specific logs and data ingested depend on your design and requirements, allowing for flexible and tailored monitoring based on your operational needs.

Azure Event Hubs is Microsoft's platform designed for collecting and managing large volumes of events in real time. In practice, it acts as an entry point for all data coming from applications, services, or IoT devices, allowing it to be conveyed in a single, centralized stream. Event Hubs can handle millions of events per second, making it the ideal choice when you need to acquire and distribute data quickly and scalably. Once collected, the information can be processed in real time with tools such as Azure Stream Analytics or sent to destinations such as Azure Storage, Data Lake, or Azure Monitor Logs for further analysis.

Azure Monitor tathu use Log Analytica has a different purpose. It is designed for operational monitoring: it collects logs and metrics from Azure resources, analyzes them, and displays them to help identify problems, trends, or situations that require attention. Although it can receive diagnostic data, it is not designed to handle high-speed event streams from external sources, as Event Hubs does.
