Both Azure Application Insights and Azure SQL Database Intelligent Insights send their diagnostic and telemetry data to Azure Monitor Logs. The service used to query this data is Azure Log Analytics. The query language used within Azure Log Analytics is the Kusto Query Language (KQL). Although KQL is the specific language, "Azure Log Analytics" is the correct option as it represents the platform and its associated query capability for analyzing this monitoring data. The other options are query languages for different database systems and are not used for querying Azure Monitor telemetry.

A. PL/pgSQL: This is a procedural programming language for the PostgreSQL database system, not for querying logs in Azure Monitor.

B. Transact-SQL: This is used to query the data within an Azure SQL Database, not the monitoring and diagnostic logs stored in Azure Monitor Logs.

D. PL/SQL: This is Oracle Database's procedural extension for SQL and is irrelevant to querying Azure monitoring services.

1. Microsoft Docs | Azure Monitor | Log queries in Azure Monitor: "Azure Monitor Logs is based on Azure Data Explorer

and log queries are written by using the same Kusto Query Language (KQL). KQL is a rich language designed to be easy to read and author

so you should be able to start writing queries with some basic guidance."

2. Microsoft Docs | Azure Application Insights | Application Insights data model: "All telemetry in Application Insights is represented as a data model of typed telemetry items... All telemetry is ultimately stored in an Azure Monitor Logs workspace as traces

exceptions

requests

etc."

3. Microsoft Docs | Azure SQL Database | Use the Intelligent Insights diagnostics log: "You can use Azure Monitor logs with Log Analytics to write queries on the log data and to create alerts... To access

query

and analyze the Intelligent Insights log streamed to Azure Monitor logs

you need to go to the Log Analytics workspace."
