Background Tasks for Extracts
The Background Tasks for Extracts view displays extract-specific tasks that run on the server.
Understand this view
To better understand this pre-built admin view, make note of the following:
- The table, "What Extracts Ran on this Server," lists the extracts that ran in the time period specified in Timeline.
- You can click Success or Error to filter the table based on status.
- You can also click a specific task to update the "How Much Time did Extracts Take" graph for the selected task.
- The table, "How Many Extracts Succeeded or Failed," updates for the status (success or failure) of the task, but the count of extracts that succeeded or failed does not change.
Tasks can have a status of success or error.
|Error—Server was unable to complete the task.|
|Success—Server completed the task.|
