Viewing Information of a Historical Cluster

Choose Clusters > Cluster History and click the name of a target cluster. You can view the cluster configuration information, nodes, auto scaling information, component information, job information, bootstrap action, and tags.

The following table describes the parameters for the historical cluster information.

**Table 1** Basic cluster information
Parameter	Description
Cluster Name	Name of a cluster. The cluster name is set when the cluster is created.
Cluster Status	Status of a cluster.
Cluster Version	Cluster version
Cluster Type	Type of the cluster to be created.
Obtaining a 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.
Default Subnet	Subnet selected during cluster creation. 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.
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.
Creating a 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 OBSOperateAccess permission of OBS and the CESFullAccess (for users who have enabled fine-grained policies), CES Administrator, and KMS Administrator permissions in the region where the cluster is located.
Key Pair	Name of a key pair. Set this parameter when creating a cluster. If the login mode is set to password during cluster creation, this parameter is not displayed.
Kerberos Authentication	Whether to enable Kerberos authentication when logging in to Manager. NOTE: Kerberos authentication cannot be manually enabled or disabled after the cluster is created. Set this parameter with caution when creating a cluster. If you need to change the authentication status, you are advised to create a new cluster.
Security Group	Security group name of the cluster.
Data Disk Key Name	Name of the key used to encrypt data disks. To manage the used keys, log in to the key management console.
Data Disk Key ID	ID of the key used to encrypt data disks.
Component Version	Version of each component installed in the cluster.
Agency	Delegates ECSs or BMSs to manage some of your resources.
