SHOW HOSTS

The SHOW HOSTS statement shows the cluster information, including the port, status, leader, partition, and version information. You can also add the service type in the statement to view the information of the specific service.

Syntax

SHOW HOSTS [GRAPH | STORAGE | META];

Note

For a Nebula Graph cluster installed with the source code, the version of the cluster will not be displayed in the output after executing the command SHOW HOSTS (GRAPH | STORAGE | META) with the service name.
