Viewing Basic Cluster Information
You can monitor and manage the clusters you have created. On the
page. Click the name of a cluster to go to the cluster details page. On the displayed page, view the basic configuration and node information of the cluster.On the MRS console, operations performed on an ECS cluster are basically the same as those performed on a BMS cluster. This document describes operations on an ECS cluster. If operations on the two clusters differ, the operations will be described separately.
On the cluster details page, click Dashboard. Table 1, Table 2, Table 3, and Table 4 describe the parameters on the Dashboard tab page.
Parameter |
Description |
---|---|
Cluster Name |
The name of a cluster. Configure this parameter when creating a cluster. Click to change the cluster name. For versions earlier than MRS 3.x, only the cluster name displayed on the MRS management console is changed, while the cluster name on MRS Manager is not changed synchronously. |
Cluster Status |
The cluster status. For details, see Table 1. |
Cluster Version |
MRS version information. |
Cluster Type |
There are three types of clusters:
|
Cluster ID |
Unique identifier of a cluster, which is automatically assigned when a cluster is created. |
Created |
Time when a cluster is created. |
AZ |
Availability zone (AZ) in the region of a cluster, which is set when a cluster is created. |
Kerberos Authentication |
Whether to enable Kerberos authentication when logging in to Manager. |
Enterprise Project |
The enterprise project to which a cluster belongs. Only on the Active Clusters page, you can click the name of an enterprise project to go to its Enterprise Project Management page. |
Parameter |
Description |
---|---|
Default Subnet |
The subnet selected during cluster creation. If the subnet IP addresses are insufficient, click Change Subnet to switch to another subnet in the same VPC of the current cluster to obtain more available subnet IP addresses. Changing a subnet does not affect the IP addresses and subnets of existing nodes. A subnet provides dedicated network resources that are isolated from other networks, improving network security. |
VPC |
VPC selected during cluster creation. A VPC is a secure, isolated, and logical network environment. |
EIP |
After binding an EIP to an MRS cluster, you can use the EIP to access the Manager web UI of the cluster. If you do not need the EIP, click Unbind to unbind the EIP from the cluster. The Manager will not be accessible through the unbound EIP.
NOTE:
If you unbind the EIP from a cluster, other users may fail to access the Manager of that cluster. |
Security Group |
The security group name of the cluster. |
Parameter |
Description |
---|---|
MRS Manager |
Portal for the Manager page.
|
IAM User Sync |
IAM user information (including federated users) can be synchronized to an MRS cluster for cluster management. For details, see Synchronizing IAM Users to MRS.
NOTE:
The Components, Tenants, and Backups & Restorations tab pages on the cluster details page can be used only after users are synchronized. After an MRS 3.x cluster is synchronized, you can use the Components function. For a federated user, only information about the user that logged in the system can be synchronized. |
Data Connection |
Click Manage to view the data connection type associated with the cluster. For details, see Configuring Data Connections. |
Agency |
Click Manage Agency to bind or modify an agency for the cluster. An agency allows ECS or BMS to manage MRS resources. You can configure an agency of the ECS type to automatically obtain the AK/SK to access OBS. For details, see Configuring a Storage-Compute Decoupled Cluster (Agency). The MRS_ECS_DEFAULT_AGENCY agency has the OBS OperateAccess permission of OBS and the CES FullAccess (for users who have enabled fine-grained policies), CES Administrator, and KMS Administrator permissions in the region where the cluster is located. |
OBS Permission Control |
Click Manage and modify the mapping between MRS users and OBS permissions. For details, see Configuring Fine-Grained Permissions for MRS Multi-User Access to OBS. |
Logging |
Used to collect logs about cluster creation and scaling failures. |
Secure Communications |
Used to display the security authorization status. You can click to enable or disable security authorization. Disabling security authorization brings high risks. Exercise caution when performing this operation. For details, see Communication Security Authorization. |
Parameter |
Description |
---|---|
Billing Mode |
Billing mode of a cluster. Currently, Pay-per-use and Yearly/Monthly are supported. |
Last Transaction Order |
Order number for purchasing a cluster. This parameter is available only when Billing Mode is set to Yearly/Monthly. |
Created |
Time when the cluster is created. This parameter is available only when Billing Mode is set to Yearly/Monthly. |
Expired |
Cluster expiration time. This parameter is available only when Billing Mode is set to Yearly/Monthly. |
Upon Expiration |
The cluster will enter the grace period upon expiration. This parameter is available only when Billing Mode is set to Yearly/Monthly. |
On the cluster details page, click Nodes. For details about the node parameters, see Table 5.
Parameter |
Description |
---|---|
Configure Task Node |
Used to add a Task node. For details, see Adding a Task Node. For 3.x and later versions, this operation applies only to the analysis cluster, streaming cluster, and hybrid cluster. |
Add Node Group |
Used to add node groups. This method applies only to customized clusters of 3.x or later. For details, see Adding a Node Group. |
Node Group |
Node group name. |
Node Type |
Node type:
On the Nodes tab page, click next to a node group name to unfold the nodes contained in the node group. Click a node name to remotely log in to the ECS using the password or key pair configured during cluster creation. For details about the parameters, see Managing Components and Monitoring Hosts. |
Node Count |
Number of nodes in a node group. |
Billing Mode |
Billing mode of the cluster you purchased, including Pay-Per-Use and Yearly/Monthly. |
