This topic describes how to view the information about Data Transmission Service units (DUs) of a Data Transmission Service (DTS) dedicated cluster.

Scenarios

  • You can view the node specifications, total number of DUs, available DUs, DU usage, overcommit ratio, creation time, and expiration time of a DTS dedicated cluster.
  • If a data migration, data synchronization, or change tracking task fails to be configured in a DTS dedicated cluster, you can view the resource usage of the DTS dedicated cluster to find the solution.

Prerequisites

A DTS dedicated cluster is created. For more information, see Create a DTS dedicated cluster.

Procedure

  1. Go to the Dedicated Cluster page.
  2. In the top navigation bar, select the region in which you want to create a DTS dedicated cluster.
  3. On the Cluster Task page, click the name of the DTS dedicated cluster that you want to view.
  4. Optional:In the left-side navigation pane, click Cluster Management.
  5. In the Basic Information section, view the DU information such as Number of remaining available DUs in the cluster and Total number of DUs in the cluster. DTS dedicated cluster
    If a task fails to be configured in the DTS dedicated cluster, you can select a solution based on the resource usage or status of the DTS dedicated cluster.
    Resource usage or cluster statusSolutionReferences
    Insufficient number of available DUs
    • Raise the overcommit ratio to increase the total number of DUs in the cluster. This increases the number of available DUs.
    • Add more nodes to increase the total number of DUs in the cluster. This increases the number of available DUs.
    • Create another DTS dedicated cluster so that the total number of DUs of all clusters meets your requirements for configuring DTS tasks.
    Important Total number of DUs in a DTS dedicated cluster = 15 × Number of nodes in the DTS dedicated cluster.
    High disk usageIncrease the disk space of cluster nodes to reduce the disk usage. Increase the storage space of nodes in a DTS dedicated cluster
    Expired and not releasedManually renew the DTS dedicated cluster or enable auto-renewal for the DTS dedicated cluster. Manually renew a DTS dedicated cluster
