Dataphin:Manage collection instances

Permissions

Super administrators, system administrators, and custom global roles with the Collection Task And Collection Instance-Management permission can manage collection instances.

Procedure

1. In the top menu bar of the Dataphin homepage, select Administration > Metadata.

2. In the left-side navigation pane, select Metadata Collection > Collection Instance to go to the Collection Instance page.

   This page shows instances from the last 7 days, including instance name, execution status, data source, data source encoding, data source type, runtime, execution method, executor, and task owner.

   • Data Source: Click a data source name to go to Management Hub > Data Source Management and view its details.

   • Execution Status: Each instance has one of the following statuses: Success, Failed, Running, Waiting, or Not Running/Paused. The status applies only to a single operation. Available operations vary by status, as listed in the following table.

     Execution Status	Operations
     Success	Collection Change Overview, View Run Log, View Collection Task.
     Failed	Rerun, View Run Log, View Collection Task.
     Running	Stop, View Run Log, View Collection Task.
     Waiting	Stop, View Collection Task.
     Not Running/Paused	View Collection Task.

3. (Optional) Search for instances by name, or use quick filters to view instances you own, instances you executed, or failed instances. You can also filter by execution status, data source type, data source environment, data source, task owner, executor, or execution method.

4. The following operations are available in the Actions column.

   Operation	Description
   Collection Change Overview	Click the icon to view metadata changes compared to the previous successful collection, including data source, collection scope, collection policy, object statistics (new, updated, deleted), table details, view details, and field details. Object Statistics: Displays object counts from the data source after a successful collection. Change Overview List: Shows metadata additions, updates, and deletions compared to the previous successful collection.
   Rerun	Rerun a single instance: Click the icon in the Actions column to rerun a failed instance. Batch rerun: Select multiple instances or click Select All at the bottom, then click the icon at the bottom to rerun failed instances. Note Rerunning may take a long time.
   Stop	You can stop instances in the Running or Waiting state. Stop a single instance: Click the icon in the Actions column. Batch stop: Select multiple instances or click Select All at the bottom, then click the icon at the bottom. Note After being stopped, the instance status changes to Failed. Stop a task when the collection source is unreachable, the task configuration is incorrect, or a system exception prevents normal execution. Check the run log to troubleshoot.
   View Run Log	Click the icon to view the run log. Each collection task maps to a workflow. Search by node ID or name, filter by run status, or use the quick filter for Failed logs. Switch between task types in the left-side node list: Dlink nodes support log information, exception details, performance diagnostics, and run code. Other task types show log information only. For failed nodes, you can click the Rerun button to rerun the instance. When a task's collection frequency is Monthly, the system generates a dry-run instance by default, marks it with a dry-run identifier, and sets it to successful. Failed nodes are automatically rerun based on the configured retry count and marked with an automatic retry identifier.
   View Collection Task	Click the instance name or the icon to go to the collection task list, filtered to the task for this instance.
