    Modifying Configuration Item

    Click Batch Modify to modify configuration items. Applicable restrictions are as described above.


    If the cluster health status is YELLOW or RED, or there is an index in the cluster that has no replicas, you will be prompted to force restart if you try to modify the configuration items. In this case, there will be a high risk if you update the configuration, and you are recommended to repair the cluster status first by adding replicas to all indices.

    If you are aware of the risk and still want to update the configuration, you can check the "Force Restart" box and click OK to restart. For more information, please see the figure below:
