Viewing Details of a DCS Instance

On the DCS console, you can view DCS instance details.


  1. Log in to the DCS console.

  2. Click image1 in the upper left corner and select a region and a project.

  3. In the navigation pane, choose Cache Manager.

  4. Search for DCS instances using any of the following methods:

    • Search by keyword.

      If you do not select an attribute and enter a keyword in the search box, the system searches for instances by instance name by default.

    • Select attributes and enter their keywords to search.

      Click the search box, select an instance attribute, and enter a keyword to search. You can select multiple attributes at a time.

      For example, choose Status > Running, Type > Master/Standby, and Cache Engine > Redis 5.0.

    For more information on how to search, click the question mark to the right of the search box.

  5. On the DCS instance list, click the name of a DCS instance to display more details about it. The following table describes the parameters.

    Table 1 Parameter description




    Instance Details


    Name of the DCS instance. To modify the instance name, click image2.


    State of the chosen instance.


    ID of the chosen instance.

    Cache Engine

    Cache engine and cache engine version used by the DCS instance. For example, Redis 4.0.

    Instance Type

    Type of the selected instance. Currently, supported types include single-node, master/standby, Proxy Cluster, and Redis Cluster.

    Cache Size

    Specification of the chosen instance.

    Used/Available Memory (MB)

    The used memory space and maximum available memory space of the chosen instance.

    The used memory space includes:

    • Size of data stored on the DCS instance

    • Size of Redis-server buffers (including client buffer and repl-backlog) and internal data structures


    CPU of the DCS instance.


    Time at which the chosen instance started to be created.


    Time at which the instance was created.


    Description of the DCS instance. To modify the description, click image3.


    Time when maintenance takes place. To modify the time window, click the image4 icon.


    Password Protected

    Currently, password-protected access and password-free access are supported.

    Connection Address

    Domain name and port number of the instance. You can click image5 to change the port.


    • The instance has a domain name address if it was created after DCS has been interconnected with DNS. Instances created before the interconnection only have IP addresses and cannot be changed to domain name access.

    • For a master/standby DCS Redis 4.0 and later instance, Connection Address indicates the domain name and port number of the master node, and Read-only Address indicates the domain name and port number of the standby node. When connecting to such an instance, you can use the domain name and port number of the master node or the standby node. For details, see Architecture of Master/Standby DCS Redis 4.0/5.0/6.0 Instances.

    • You can change the port only for a DCS Redis 4.0 and later instance, but not for a DCS Redis 3.0 instance.

    IP Address

    IP address and port number of the chosen instance.



    Availability zone in which the cache node running the selected DCS instance resides.


    VPC in which the chosen instance resides.


    Subnet in which the chosen instance resides.

    Security Group

    Security group that controls access to the DCS instance. To modify the security group, click image6.

    This parameter is displayed only for DCS Redis 3.0 instances. DCS for Redis 4.0/5.0/6.0 are based on VPC Endpoint and do not support security groups. You can click configure to configure the whitelist.
