View the dashboard

The Operation Center service of DataWorks displays the running information about nodes in a dashboard on the Overview page to help you improve the efficiency of node O&M. In the dashboard, you can view information such as metrics that require your special attention, the overall node running status, and trends on scheduling resources.

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 where the target workspace resides. Find the target workspace and click Data Analytics in the Actions column.
4. On the DataStudio page, click in the upper-right corner and choose All Products > Task Operation > Operation Center. The Overview page appears.
   

   Note The dashboard displays statistics on auto triggered nodes and auto triggered node instances. Other types of nodes or node instances are not included.

   The Overview page contains the following sections: Focus on, RUNNING state distribution, Task Completion, Scheduling resource allocation, Runtime ranking, Error ranking in recent month, Instances Run in the Last Month, and Node Types.

   • The Focus on section displays the following information:
     • The numbers of node instances that require your special attention, including failed node instances, slow node instances, and node instances pending for resources. The statistics are collected on node instances whose data timestamp is the day before the current date. A node instance is considered a slow node instance when it meets the following conditions:
       • The node instance is running.
       • The running time of the node instance exceeds 30 minutes.
       • The node instance recurred for more than 10 days, and the average running time is not less than 15 minutes.
     • The numbers of isolated nodes, paused nodes, and expired nodes.
       • An isolated node is a node that does not have an ancestor node. In this case, the node cannot be run. For example, if you rename the parent node of a node, the dependency becomes invalid and the node becomes an isolated node.
       • After a node is paused, the node no longer generates node instances and cannot be scheduled.
       • If a node is not triggered at the specified time, the node becomes expired.

     The statistics in this section are updated when you load the page. 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 in a timely manner to avoid impacts on your business.

   • The RUNNING state distribution section displays the distribution of auto triggered node instances in different states whose data timestamp is the day before the current date. The statistics in this section are updated when you load the page. You can click a sector in the pie chart to go to the details page and view the specific node instances.
   • The Task Completion section shows three lines in different colors, representing the numbers of node instances that are completed or not run between 00:00 and 23:00 of today and yesterday, as well as the historical average, on the Run successfully and Not running tabs. You can also select a node type from the Node Type drop-down list to view the status of specific node instances.
     The line chart displays the numbers of auto triggered node instances that were completed today and yesterday, as well as the historical average. If the deviations among the three numbers are large, an exception occurred during a certain period of time. Further check and analysis are required.

     Note The statistical method used by the Operation Center service has been changed. Only node instances in the production environment are counted. Therefore, the line representing the number of node instances completed today will show obvious fluctuations.
   • The Scheduling resource allocation section displays the usage of a specific resource group and the number of node instances that were running at different time points in the last 24 hours. You can select a resource group from the Resource Group selection drop-down list in the upper-right corner.
   • The Runtime ranking section ranks nodes based on their running time, time pending for resources, or excess running time compared with nodes that are properly run. The statistics in this section are updated every day. Nodes that were completed on the day before the current date are ranked in this section.
   • The Error ranking in recent month section ranks nodes with the most errors in the last month and displays the top ten nodes. The statistics in this section are updated every day. You can view the name, ID, number of occurred errors of each node.
   • The Instances Run in the Last Month section displays the trends on the numbers of nodes and node instances that are scheduled in the specified time range in the production environment. The statistics in this section are updated every day. The widest time range that this section supports is one year.
   • 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, certain node types are merged for display.
