 ERROR 1105 (HY000): The workload in selected time window is too low, with which TiDB is unable to reach a capacity estimation; please select another time window with higher workload, or calibrate resource by hardware instead
 ```
 
-The capacity estimation function requires monitoring metrics data according to the actual workload, including `resource_manager_resource_unit`, `process_cpu_usage`, `tikv_cpu_quota`, and `tidb_server_maxprocs`. If the corresponding monitor data is empty, an error is reported with the corresponding monitor item name, as shown in the following example. When there is no workload, `resource_manager_resource_unit` is empty, and this error is also reported.
