Data Integration Instance

Feature overview

Functional positioning

Data Integration Instance is used to centrally view runtime records generated by data integration tasks, and provides category retrieval, combined query, instance details, task flow, task logs, and log download capabilities.

In short: this is the runtime record center for data integration tasks. You can quickly confirm whether a task succeeded, then further view its flow and logs.

Usage suggestions

First confirm the current project, then narrow the scope by data integration category. After finding the target instance, verify execution status and time first, then enter Details or download logs when troubleshooting is needed.

Main features

• Combination positioning: Supports finding instances by data integration category, task instance name, execution status and execution date.
• Running Overview: Centrally displays instance number, execution type, status, start and end time, and responsibility information.
• Process View: View the task summary, process nodes and node status on the details page.
• Log acquisition: View read-only task logs, or download the .log file of the current instance.
• List Assist: Supports displaying and hiding the query area, refreshing, displaying and hiding columns, and paged browsing.

Scope

This page is suitable for querying and troubleshooting already generated data integration instances. It is not used for creating, editing, deleting, rerunning, stopping or scheduling tasks.

3. View the read-only log content of the current instance.
4. When the log is empty, the content area remains blank; this behavior does not mean that the page has failed to load.
5. When the instance is in the running state, the log and process node status will be refreshed regularly; the refresh will stop after the instance enters the end state.

Data integration instance task log tab

Download instance logs

1. Return the list of data integration instances.
2. Click [Download Log] in the target instance row.
3. The page displays a download waiting prompt.
4. After the download is successful, the browser saves the .log file named with the task instance name.

FAQ

• Why is there no target instance in the query results?
  First confirm the current project and data integration category scope, and then check the task instance name, execution status and execution date conditions; click [Reset] when you need to restore the default list.

• **How ​​to name the log file?**The
  download file has the task instance name as the main body and uses the .log extension.
