The following pseudocode shows how the Seconds_Behind_Master value is calculated. if (SQL thread is running) //If the SQL thread is started { if (SQL thread processed all the available relay log) //If the binlog pulled by the I/O thread from the master node is the same
Master Node AZs You can check how many master nodes are supported in a cluster. To check data such as the resource usage of the master nodes, click View Monitoring in the upper right corner to go to the Monitoring (Monitoring Center) page.
