When a node in a baseline, one of its ancestor nodes, or a node on the key path fails or slows down, a corresponding event is generated. You can view event details on the event management page.
Background information
The smart baseline feature captures exceptions that might prevent nodes from completing on time and sends early warnings to ensure that critical data is generated within the expected timeframe in scenarios with complex dependencies. For more information, see Overview of smart baselines.
Limitations
The event management feature is available only in DataWorks Standard Edition or higher. If you are using a lower edition, upgrade your DataWorks instance to use this feature. For more information, see Feature comparison among DataWorks editions.
Key concepts
-
Error: A node fails to run.
-
Slowdown: The runtime of a node is significantly longer than its recent average.
If a node first slows down and then fails, two separate events are generated.

Filters |
Use the filter area on the event list page to filter events by specific criteria. You can search by Owner, Detected At, Event Status, Event Type, Priority, Node, or Node Instance. Each row in the search results corresponds to an event for an anomalous node. |
|
Event list |
The list displays detailed information for each event, such as Event ID, Event Status, Workspace, Node Instance, Priority, Type, Time, and Worst Baseline. In the Actions column, you can View View Details, Handle event, and Ignored event.

View event details
Click View Details in the Actions column of an event to view its occurrence time, alert time, recovery time, the node's run history, and the detailed node log.
-
General: Displays basic information about the event, such as the name of the node instance that generated the event, the event type, and the event owner.
-
Worst Baseline: If the node associated with the current event has multiple descendant nodes that are part of enabled baselines, the baseline with the least alert margin is considered the worst baseline.
-
Time Information: A timeline of the event, including its occurrence time, detection time, first alert time, last handling time, and recovery time. Click View Alert Content to navigate to the corresponding alert details page.
-
Affected Baselines: A list of baselines whose data output is affected by the current event.
-
History: A trend chart that shows the daily data output time of the node associated with the current event.
-
Node Logs: The run log of the scheduled node instance that is associated with the current event for the current day.
