 ## Monitor TopSQL
 
-TiDB Cloud Clinic provides TopSQL information, enabling you to monitor and visually explore the CPU overhead of each SQL statement in your database in real time. This helps you optimize and resolve database performance issues.
+TiDB Cloud Clinic provides TopSQL information to help you visually analyze the most resource-intensive queries on a specific TiDB or TiKV instance over a period of time. By default, TopSQL continuously collects CPU load data. For TiKV instances, if TiKV network IO collection is enabled, you can also inspect `Network Bytes` and `Logical IO Bytes`, and analyze hotspots by `Query`, `Table`, `DB`, or `Region`. This helps you identify and troubleshoot performance issues from multiple resource dimensions instead of CPU alone.
