Measurements made by the test
Measurement	Description	Measurement Unit	Interpretation
Opened tables	Indicates the number of tables that were opened on this node during the last measurement period.	Number	If this value is high, then it indicates that the “table_cache” value is probably too small.
Created tmp disk tables	Indicates the number of implicit temporary tables that were created on the disk of this node, while executing statements during the last measurement period.	Number	If the value for this measure is high, consider increasing the ‘tmp_table_size’ configuration setting for the server.
Created tmp tables	Indicates the number of implicit temporary tables that were created in the memory created while executing statements during the last measurement period.	Number
