Outputs of the test : One set of results for each node in the target MySQL Cluster database server being monitored
The measures made by this test are as follows:
| 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. |
