Your company has a Microsoft SQL Server database hosted on a Microsoft Azure virtual machine. You create several reports that display data from the database. Users report that the reports are slow…

SQL Server Profiler captures a trace of database events for detailed analysis over time, but it does not provide a real-time, visual execution plan or immediate insight into the impact of a specific index on a running query.

Query Store collects historical query execution plans and runtime statistics, which is excellent for identifying regressions and long-term performance trends, but it's not designed for real-time, immediate visual feedback on a currently executing query.

Database Engine Tuning Advisor analyzes workloads to recommend indexing strategies and other physical design structures, but it does not provide tools to monitor or verify the performance improvement of an index after it has been created.

Live Query Statistics provides real-time insights into the execution plan of a running query, visually displaying the progress and actual runtime statistics for each operator. This allows you to immediately see how the query is performing, identify bottlenecks, and directly observe if the newly created index has changed the execution plan or significantly improved performance.
