DataWorks:View and manage manually triggered node instances

Last Updated:Aug 15, 2023

Manually triggered node instances are generated when manually triggered nodes are run. You can view the details about and perform the related operations on an auto triggered node instance in the list of auto triggered node instances or in the directed acyclic graph (DAG) of the instance.

Important
  • Manually triggered node instances created in DataWorks V1.0 are listed as the Manually Triggered Node type, and those created in DataWorks V2.0 or later are listed as the Manually Triggered Workflow type.

  • You can configure alert rules for the status of only auto triggered node instances. You cannot configure alert rules for the status of manually triggered node instances, data backfill instances, and test instances.

  • You must purchase DataWorks Professional Edition or a more advanced edition to use the instance diagnostics feature for manually triggered node instances.

Go to the Manual Instance page

  1. Log on to the DataWorks console. In the left-side navigation pane, choose Data Modeling and Development > Operation Center. On the page that appears, select the desired workspace from the drop-down list and click Go to Operation Center.

  2. In the left-side navigation pane of the Operation Center page, choose Manual Task > Manual Instance. On the Manual Instance page, you can view the list and DAGs of manually triggered workflows that contain manually triggered node instances.

Manually triggered workflows

Operation

Description

Filter

Search for the required workflows by specifying the filter conditions in the area marked with 1 in the preceding figure.

You can search for workflows by workflow name or by specifying one or more of the following filter conditions:Type, Owner, Data Timestamp, and Run At.

View the status of manually triggered node instances

The Workflow column displays the status of normal instances (excluding dry-run instances and frozen instances) in the current workflow and the number of instances in each state by using the following icons:
  • Running: the number of running instances in the current workflow
  • Successful: the number of successful instances in the current workflow
  • Failed: the number of failed instances in the current workflow
  • More features: the number of instances that are not in the preceding states in the current workflow

DAG

Open the DAG of the workflow by click DAG in the Actions column in the area marked with 3 in the preceding figure. You can view the running results of the node instances that belong to the workflow. For more information, see View the DAG of a manually triggered workflow.

View the DAG of a manually triggered workflow

To view the DAG of a workflow, click the name of the workflow or click DAG in the Actions column. In the DAG, you can right-click a node instance to perform related operations. DAG

Note

In the list of manually triggered workflows, click the name of a manually triggered workflow. The DAG of the workflow appears on the right. The workflow may contain multiple nodes.

Operation

Description

View Runtime Log

View the run logs of the node instance in the Running, Successful, or Failed state.

Note
  • You cannot manually delete a node instance. DataWorks automatically deletes the node instance about 30 days after the node instance expires.

  • The instances of a node that runs on the shared resource group for scheduling can be retained for a month after they expire. The logs of the node instances can be retained for a week. If the size of the logs generated for a node instance exceeds 3 MB, the system clears the logs every day.

  • The instances of a node that runs on an exclusive resource group for scheduling can be retained for a month after they expire. The logs of the node instances can also be retained for a month.

Instance Diagnose

Track the status of the node instance and identify problems. For more information, see Intelligent diagnosis.

View Code

View the code of the node instance.

Edit Node

Go to the DataStudio page to modify the node instance of the workflow.

View Lineage

View the lineage of the node instance.

Stop

Stop the node instance.

Rerun

Rerun the node instance if the node instance fails or is not run as scheduled.

Note

You can rerun only node instances in the Successful or Failed state.
