Overview
<TencentDB for MongoDB allows you to view the instance node information, including node ID, role, running status, used capacity, and other information. In addition, it supports node management operations, such as adjusting node specification, promoting replica node to primary node, enabling read-only replica, and configuring primary/replica failover. You can use node management to efficiently manage instance nodes and locate node-related exceptions during operation.
Operation Steps
1. Log in to the TencentDB for MongoDB console.
2. In the MongoDB drop-down list on the left sidebar, select Replica Set Instance or Sharded Instance. The operations for Replica Set Instance and Sharded Instance are similar.
3. On the right side, select a region at the top of the Instance List page.
4. In the Instance List, find the target instance whose node you want to view.
5. Click the instance ID to enter the Instance Details page, and click the Node Management tab.
6. View the mongod and mongos node information.
