wsrep_connected

DETAILS

When a cluster node starts, it attempts to establish network connectivity with the other nodes specified by the wsrep_cluster_address system variable. As nodes connect, they form components. Once they establish connectivity with the Primary Component and synchronize databases, they become operational.

This status variable indicates whether the node has established a connection with a component. To determine whether it has established a connection with the Primary Component, see the wsrep_cluster_status status variable.

EXAMPLES

Use the SHOW STATUS statement to view the current status:
