Turns off snapshots taken by the Global Status History.

Syntax

CALL mysql.rds_disable_gsh_collector;

mysql.rds_disable_gsh_rotation

Turns off rotation of the mysql.global_status_history table.

Syntax

CALL mysql.rds_disable_gsh_rotation;

mysql.rds_enable_gsh_collector

Turns on the Global Status History to take default snapshots at intervals specified by rds_set_gsh_collector.
