The location of TiDB cluster hotspots can be diagnosed and located from the following dimensions. When using it, it is recommended to use the “TiDB Dashboard” related function menu first:


- TiDB Dashboard 
  - Visualize traffic pages, key ranges for read/write hotspots, and database objects.
  - The Slow Queries page allows you to retrieve and view all slow queries in the cluster.
  - SQL statement analysis, which allows you to view the execution of all SQL statements on the cluster, including analysis of SQL statements that take a long time to execute in aggregate or a single execution.
- Grafana 
  - Hot Write panel in TikV-Trouble-Shooting
  - TikV-Details —> Thread_CPU 
    - Is there any obvious TiKV that coprocessor cpu is particularly high (read hot spot)
    -...
  - PD metrics
    - Statistics - hot write
    - Statistics - hot read
