Viewing Details of a DCS Instance

Procedure

1. Log in to the DCS console.
2. Click in the upper left corner of the console 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 Parameters on the Basic Information page of a DCS instance

   Section	Parameter	Description
   Instance Details	Name	Name of the DCS instance. To modify the instance name, click .
   	Status	State of the chosen instance.
   	ID	ID of the chosen instance.
   	Cache Engine	Cache engine and cache engine version used by the DCS instance. For example, Redis 5.0.
   	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	CPU of the DCS instance.
   	Created	Time at which the chosen instance started to be created.
   	Run	Time at which the instance was created.
   	Maintenance	Time range for any scheduled maintenance activities on cache nodes of this DCS instance. To modify the time window, click the icon.
   	Description	Description of the DCS instance. To modify the description, click .
   Connection	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 next to Connection Address to change the port. NOTE: 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. 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.
   Network	AZ	Availability zone in which the cache node running the selected DCS instance resides.
   	VPC	VPC in which the chosen instance resides.
   	Subnet	Subnet in which the chosen instance resides.
   	Security Group	Security group that controls access to the DCS instance. Only Redis 3.0 supports access control with security groups. To modify the security group, click . DCS Redis 4.0 and later are based on VPC Endpoint and do not support security groups. You can click configure the whitelist to configure the whitelist.
   Instance Topology	-	Hover the mouse pointer over an instance to view its metrics, or click the icon of an instance to view its historical metrics. Topologies are supported only for master/standby and cluster instances.
