The Overview page displays the overall O&M information, including the metrics that require your special attention, overall execution information about nodes, and trends on scheduling resource changes. It also displays information about Data Integration, including the distribution of batch synchronization nodes and real-time synchronization nodes in different states and the data synchronization progress of batch synchronization nodes and real-time synchronization nodes. This helps improve O&M efficiency.

Go to the Overview page

  1. Log on to the DataWorks console.
  2. In the left-side navigation pane, click Workspaces.
  3. In the top navigation bar, select the region in which the workspace that you want to manage resides. Find the workspace and click Data Development in the Actions column.
  4. Click the Icon icon in the upper-left corner and choose All Products > Task Operation > Operation Center. The Workbench Overview tab of the Overview page appears.

View the statistics on the Workbench Overview tab

The Workbench Overview tab displays the statistics only on auto triggered nodes and auto triggered node instances. You can view the following information on the Workbench Overview tab:
  • The Focus on section displays the following information:
    • The numbers of auto triggered node instances that require your special attention, including failed instances, slow running instances, and instances waiting for resources. A node instance is considered a slow running instance if it meets the following conditions:
      • The node instance is running.
      • The execution time of the node instance exceeds 30 minutes.
      • The execution time of the node instance is at least 15 minutes longer than the average execution time of the node instance during the last 10 days.
    • The numbers of isolated nodes, paused nodes, and expired nodes.
      • The Isolated Nodes metric indicates the number of auto triggered nodes that do not have parent nodes. If an auto triggered node does not have a parent node, it becomes an isolated node. In this case, the node cannot be run. For example, if you change the output name for the parent node of a node, the dependency becomes invalid. For more information about the causes and impacts of isolated nodes and how to fix them, see What is an isolated node? and How can I fix an isolated node?.
      • The Paused Nodes metric indicates the number of auto triggered nodes that are in paused or frozen state. If an auto triggered node is paused, the instances that are generated are also frozen. A frozen instance cannot be run and blocks descendant nodes. For more information about the freeze operation, see Node freezing and unfreezing.
      • The Expired Nodes metric indicates the number of auto triggered nodes of which the effective period of scheduling expires. An auto triggered node automatically generates and runs auto triggered node instances within the effective period of scheduling. If the effective period of scheduling expires, the node cannot generate instances or be automatically scheduled.
    Focus on

    The Focus on section displays statistical data of yesterday, the day before yesterday, the previous week, or a time range of no longer than seven days. You can click a type of node or node instance to go to the details page and view the specific nodes or node instances. We recommend that you fix these nodes and node instances at the earliest opportunity to avoid impacts on your business.

  • The Running Status Distribution section displays the distribution of auto triggered node instances in different states. You can specify to view statistical data of yesterday, the day before yesterday, the previous week, or a time range of no longer than seven days. The statistics in this section are updated when you load the page. You can click a sector in the pie chart to view the auto triggered node instances in the corresponding state. Running Status Distribution
  • The Node Completion section displays the completion status of auto triggered node instances between 00:00 and 23:00 of the current day. You can view the number of auto triggered node instances that are successfully run or not run today and yesterday. You can also view the historical average number of auto triggered node instances that are successfully run or not run. In addition, you can select a node type to view the status of specific auto triggered node instances. Node type
    The line chart displays the number of auto triggered node instances that are run today, the number of auto triggered node instances that were run yesterday, and the historical average number of auto triggered node instances that are run. If the deviations among the three numbers are large, an exception occurred during a specified time range. You must perform a further check and analysis.
    Note The statistical aggregation method used by Operation Center has been changed. Only auto triggered node instances in the production environment are counted. Therefore, the line that represents the number of auto triggered node instances that are run today shows obvious fluctuations.
  • The Scheduling Resource Allocation section displays the resource usage and the trend on the number of instances that are run on the resource group over a time range of no longer than seven days. You can select a resource group from the drop-down list in the upper-right corner of this section to view the resource usage and the trend on the number of instances that are run on the resource group in the current workspace over time. Scheduling Resource Allocation
    The Number of Instances line shows the number of node instances that are run on the current resource group. The Resource Usage line shows the percentage of the resources used by the node instances that are run on the specified resource group.
    Note
    • The resources that are used by Data Integration nodes are not counted.
    • The Resource Usage and Number of Instances metrics apply to resource groups. For example, if multiple workspaces share the exclusive resource group that you use, this section displays the resource usage and the trend on the number of instances that are run on the resource group in all workspaces.
  • The Runtime Ranking section ranks nodes based on their execution time, time spent in waiting for resources, and slow execution time. The statistics in this section are updated every day. Nodes that are successfully run on the day before the current day are ranked in this section. Runtime Ranking
  • The Error Ranking in Recent Month section ranks nodes on which errors occurred within the last month and displays the top 10 nodes. The statistics in this section are updated every day. You can view the Node ID, Node Name, and Errors for each node. Error Ranking in Recent Month
  • The Number of Auto Triggered Nodes section displays the trends on the numbers of auto triggered nodes and auto triggered node instances in a specified time range in the production environment. The statistics in this section are updated every day. You can view the trends on the numbers of auto triggered nodes and auto triggered node instances in a time range as wide as one year. Number of Auto Triggered Nodes
  • The Node Types section displays the distribution of nodes in a pie chart. The statistics in this section are updated when you load the page. The pie chart displays a maximum of eight node types. If you have created more than eight types of nodes, specific node types are merged for display. Node Types
