Cluster operation

This topic introduces the cluster operation of Dashboard, including cluster node, cluster service, cluster scaling, service configuration, and member management.


On this page, the information of all nodes will be shown, including the cluster name, Host(SSH_User), CPU (Core), etc.

  • To add a node quickly, click Add node and enter the following information, the Host, SSH port, SSH user, SSH password, and select a NebulaGraph package.
  • Click the plus button to view the process name, service type, status, runtime directory of the corresponding node.

    • Click Node monitoring to jump to the detailed node monitoring page. For more information, see Cluster monitoring.
    • Click Edit node to modify the SSH port, SSH user, and SSH password.
    • If a node has no service, you can delete the node.


  • On this page, you can select the service type, service status, and Host to filter the shown data, quickly select one or multiple services, and start/stop/restart the service with one click.


If you click Stop/Restart, the running task will be stopped instantly, which may cause data inconsistency. It is recommended to perform this operation during the low peak period of the business.

Update config

On this page, you can modify configuration files of Storage and Graph services. For more information, see Storage service configuration and Graph service configuration. Updating configuration files is a batch operation, and each Storage/Graph configuration file will be modified.

  • After clicking Save, the configuration will take effect after the next service restart.
  • Click Save and restart to directly restart the service to make the configuration take effect immediately.


    If you click Save and Restart, the running task will be stopped and the cluster will be restarted instantly, which may cause data inconsistency. It is recommended to perform this operation during the low peak period of the business.
