Check replication status

Это содержимое пока не доступно на вашем языке.

On a switch with a hot stand-by server, the database is replicated from the leader host to the follower host. These methods tell you whether replication is on, which hosts take part and how far the follower lags behind. Use them in your monitoring. Only the root customer may call them.

The methods support trusted mode with i_customer.
