Viewing Instance Information

Last updated: 2022-07-11 15:57:31

    Overview

    After purchasing a TencentDB for Redis instance, you can quickly view its details in the console, such as the status, capacity usage, master/replica nodes in the cluster, and network status. You can also perform Ops and management operations efficiently.

    Prerequisites

    Viewing the Instance List

    1. Log in to the TencentDB for Redis console.
    2. Above the instance list on the right, select the region.
    3. In the instance list, find the target instance.
    • In the search box in the top-right corner, you can search for the target instance by instance ID, instance name, private IP, or tag key.
    • If you can't find the target instance in the instance list, select Recycle Bin on the left sidebar to check whether it is isolated there due to overdue payments. For more information, see Recycle Bin.
    1. View the target instance information, such as the status, specification, and storage engine.
