-------------------------------------------------------------
Observe the Top 5 charts and tables presented in Top SQL.

The size of the color blocks in the column chart represents how much CPU resources the SQL statement consumes at that moment, and different colors distinguish different types of SQL statements. In most cases, you should pay attention to the SQL statements with larger CPU resource overhead in the corresponding time range of the chart.
