According to the Microsoft documentation, Azure Monitor collects and analyzes monitoring data from Azure resources, including Azure SQL databases. You can use Azure Monitor to monitor the performance of DB1 and run queries to analyze log data.
To use Azure Monitor, you need to configure the diagnostic settings of DB1, which define the sources and destinations of the monitoring data. The sources are the types of metric and log data to send to the destinations, such as SQLInsights, Errors, Blocks, Deadlocks, etc. The destinations are one or more locations where you want to send the monitoring data, such as a Log Analytics workspace, a storage account, or an event hub.
A Log Analytics workspace is a unique environment for Azure Monitor log data. Each workspace has its own data repository and configuration, and data sources and solutions are configured to store their data in a particular workspace. You can use a Log Analytics workspace to run queries on the log data collected from DB1 and other resources using the Kusto query language. You can also create alerts, dashboards, and workbooks based on the log data in the workspace.
A storage account is a place where you can store large amounts of unstructured data, such as files, blobs, queues, tables, and disks. You can use a storage account to archive the monitoring data from DB1 for long-term retention or backup purposes. However, you cannot run queries on the log data in a storage account directly. You would need to use another tool or service to analyze the log data in a storage account.
An event hub is a service that enables you to ingest and process large volumes of streaming data from multiple sources. You can use an event hub to stream the monitoring data from DB1 to other applications or services that can consume and analyze the data in real time. However, you cannot run queries on the log data in an event hub directly. You would need to use another tool or service to analyze the log data in an event hub.
