View the basic information about an ApsaraDB MyBase dedicated cluster

  1. Log on to the ApsaraDB MyBase console.
  2. In the upper-left corner of the page, select the region where you want to create a dedicated cluster.
  3. On the Clusters page, you can view information about the dedicated cluster. You can also download the information to an on-premises machine.
    • By default, the Dedicated Cluster ID, VPC, and Hosts columns are displayed on the Dedicated Clusters page. You can click Custom Columns icon in the upper-right corner to select the columns that you want to view. Specify the columns that you want to view
    • In the upper-right corner of the Dedicated Clusters page, you can click the Export Resources icon icon to download the information about a dedicated cluster to an on-premises machine.

  5. On the Basic Information tab, you can view the configurations of the dedicated cluster.
    View the details about a dedicated clusterThe following table describes the parameters.
    Parameter Description
    Dedicated Cluster ID The ID of the dedicated cluster.
    Dedicated Cluster Name The name of the dedicated cluster.
    VPC The virtual private cloud (VPC) in which the dedicated cluster is deployed.
    Hosts The number of hosts in the dedicated cluster.
    Instances The number of instances in the dedicated cluster.
    Host Troubleshooting Policy The policy that is used to handle host failures in the dedicated cluster. Valid values:
    Resource Allocation Policy The default policy that is used to schedule resources in the dedicated cluster. Valid values:
    CPU Overcommit Ratio The CPU overcommit ratio of the dedicated cluster. For example, if the CPU overcommit ratio is 200%, the amount of CPU resources that can be allocated to the instances in the cluster is twice the amount of CPU resources that is provided. This maximizes CPU utilization.
    Storage Overcommit Ratio The storage overcommit ratio of the dedicated cluster. For example, if the storage overcommit ratio is 200%, the amount of storage resources that can be allocated to the instances in the cluster is twice the amount of storage resources that is provided. This maximizes storage usage.
    Maximum Memory Usage The maximum memory utilization of each host in the dedicated cluster.
    Creation Time The time when the dedicated cluster was created.

    Resource Allocation Policy The default policy that is used to schedule resources in the dedicated cluster. Valid values:
    Host Troubleshooting Policy The policy that is used to handle host failures in the dedicated cluster. Valid values:
    Grant OS Permissions If you enable this feature for a dedicated cluster that runs the MySQL, SQL Server, or PostgreSQL database engine, you can log on to the hosts in the dedicated cluster to perform operations such as uploads, downloads, and software installation.
    Notice After you grant OS permissions on your dedicated cluster, you cannot change the permissions.
  5. Click OK.
