SHOW HOSTS

The SHOW HOSTS statement shows the host and version information of Graph Service, Storage Service, and Meta Service.

Syntax

SHOW HOSTS [GRAPH | STORAGE | META];

Note

  • If you return SHOW HOSTS without the service name, it will show the host information of the Storage Service, as well as the leader number, leader distribution, and partition distribution.
  • 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.
