Viewing Node Information

Last updated: 2024-04-02 16:14:18

    Overview

    TencentDB for MongoDB allows you to view the instance node information, including node ID, role, running status, and used capacity. In addition, it supports node management operations, such as adjusting node specification, promoting secondary node to primary node, enabling read-only replica, and configuring primary/secondary failover. You can use node management to efficiently manage instance nodes and locate node exceptions.
