------------------------------------------------------------
Query Summary - QPS: Different SQL types of QPS reflect the load level and request type of the database at a macro level, such as the time of day when the QPS is at its peak, whether the request type is read-more-write-less or write-dominated.

- Query Summary - CPS By Instance: Whether the CPS of the different tidb instances is balanced or not reflects the policy and balance of traffic distributed by the LB load balancer.
    - Tips: CPS is Command Per Second, the number of commands executed per second. A command may contain multiple SQL, such as a multi-query request like select 1; select 1; select 1, which contains three SQL statement.

- Query Detail - Internal SQL QPS: Usually unconcerned, it may be high in the pressure test scenario, consider turning off feedback to reduce the impact on pressure measurement.
