Viewing and Modifying Basic Settings of a DCS Instance

Viewing and Modifying Basic Information of a DCS Instance

1. Log in to the management console, and choose Application > Distributed Cache Service in the service list.
2. Click in the upper left corner of the management console and select the region where your instance is located.
3. In the navigation pane, choose Cache Manager.
4. Search for DCS instances using any of the following methods:
   • Search by keyword.

     Enter a keyword to search.

   • Select attributes and enter their keywords to search.

     Currently, you can search by name, specification, ID, IP address, AZ, status, instance type, and cache engine.

     For example, click the search box, choose Cache Engine, and then choose Redis 4.0, Redis 5.0, or Redis 6.0.

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

5. Click the name of the DCS instance to display more details about the DCS instance. Table 1 describes the parameters.

   Table 1 Parameters on the Basic Information page of a DCS instance

   Section	Parameter	Description
   Instance Details	Name	Name of the chosen instance. To modify the instance name, click the icon.
   	Status	State of the chosen instance.
   	ID	ID of the chosen instance.
   	Cache Engine	Cache version of DCS. For example, Redis 4.0. The cache version is fixed once the instance is created. To use another version, create an instance again and migrate the data.
   	Instance Type	Type of the selected instance. Currently, supported types include single-node, master/standby, Proxy Cluster, read/write splitting, and Redis Cluster. To change the instance type, see Modifying DCS Instance Specifications about the supported instance types, changing notes and procedure.
   	Cache Size	Specification of the chosen instance. To change the instance specification, see Modifying DCS Instance Specifications about the changing notes and procedure.
   	Bandwidth	Bandwidth of the DCS 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 architecture of the chosen instance.
   	Enterprise Project	Enterprise project to which the new instance belongs. Click to modify the enterprise project of the instance.
   	Maintenance	Time range for any scheduled maintenance activities on cache nodes of this DCS instance. To modify the window, click the icon. Select a new window from the drop-down list and click to save, or to cancel. The modification takes effect immediately.
   	Description	Description of the chosen DCS instance. To modify the description, click the icon.
   Connection	Password Protected	Yes: password-protected access; No: password-free access. To change the password access mode, see Configuring a Redis Password.
   	Connection Address	The domain name and port of the Redis instance to be accessed on a client within the VPC. You can click next to Connection Address to change the port. The connection address is fixed once the instance is created. NOTE: For a master/standby DCS Redis 4.0/5.0/6.0 instance, Connection Address indicates the domain name and port number of the master node, and Read-only Address indicates those 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 the architecture of a master/standby instance. You can change the port only for a DCS Redis 4.0, 5.0, or 6.0 basic instance, but not for a DCS Redis 3.0, 6.0 professional, or Memcached instance.
   	IP Address	The IP address and port of the DCS instance to be accessed on a client within the VPC. To change the instance port, click . The IP address is fixed once the instance is created. The domain name address is recommended.
   	Public Access	Currently, public access cannot be enabled for Redis instances.
   Network	AZ	Availability zone in which the instance nodes running the selected DCS instance reside.
   	VPC	VPC in which the chosen instance resides. The VPC is fixed once the instance is created.
   	Subnet	Subnet in which the chosen instance resides. The subnet is fixed once the instance is created.
   	Security Group	To control access to DCS Redis instances, configure a whitelist
   Instance Topology	-	Hover over a node to view its metrics, or click the icon of a node to view its historical metrics. Single-node instances do not display the instance topology.
   Billing	Billing Mode	Billing mode of the instance.
   	Created	Time at which the chosen instance started to be created.
   	Run	Time at which the instance was created.
