Configuration
Region
Region where a cluster is located
AZ
AZ where a cluster is located
VPC
VPC to which the cluster belongs
Subnet
Subnet to which the cluster belongs
Security Group
Security group to which a cluster belongs.
To change the security group of a cluster, click Change Security Group on the right.
NOTICE:Before changing the security group, ensure that the port 9200 required for service access has been enabled. Incorrect security group configuration may cause service access failures. Exercise caution when performing this operation.
Cluster Routing
Click Modify on the right of the parameter to modify the cluster route information. For details, see Modifying the Return Route.
Enterprise Project
Enterprise project to which a cluster belongs.
You can click the project name to view the basic information about the enterprise project.
Private Network Address
Private IP address and port number of a cluster, which can be used to access the cluster. If the cluster has only one node, the IP address and port number of only one node are displayed, for example, 10.62.179.32:9200. If the cluster has multiple nodes, the IP addresses and port numbers of all nodes are displayed, for example, 10.62.179.32:9200,10.62.179.33:9200.

Node Specifications
Specifications of nodes in a cluster
Node Storage Type
Storage capacity and storage type of nodes in a cluster
Nodes
Number of nodes in a cluster
Modifying the Return Route
The Logstash service is a hosting service. The subnet selected during cluster creation is not the primary NIC of the Logstash node. You need to add a return route pointing to the target IP address (server where public network data is stored) for each node in the cluster.
- Click the name of a cluster to view its details.
- Click Modify next to the Cluster Routing.

- IP Address: Enter the first 16 or 24 bits of the server IP address where the public network source data is stored. For example, if the source IP address is 192.168.1.1, enter 192.168.0.0 to the text box.
- Subnet Mask: If the IP Address contains 16 bits of the server IP address, set the subnet mask to 255.255.0.0. If the IP Address contains 24 bits of the server IP address, set the subnet mask to 255.255.255.0.
The subnet mask must cover the IP network segment. That is, after the subnet mask and IP address are converted into binary values, the number of 0 at the end of the IP address must be greater than the number of 0 at the end of the subnet mask.
- Modification Type: Select Add or Delete.
- Click OK.
