 Since the SQL Server backplane performs frequent polling operations, you may want to filter out successful, fast queries to reduce trace noise.

There are currently [4 different packages for SqlClient instrumentation](https://github.com/dotnet/aspire/issues/2427#issuecomment-3259572206), so your method of collecting or filtering the command details may vary if you're using Aspire's instrumentation or Azure Monitor's instrumentation.
