Event Log
The primary audit trail for all order operations in Omnium, covering status changes, workflows, payments, notifications, and errors.
Event Log
The Event Log is the primary audit trail for all order operations. Every significant action on an order — status changes, workflow executions, payment operations, notifications, errors, and more — produces an event log entry stored in Elasticsearch.
The Event Log is always active and cannot be disabled.
What Gets Logged
Events are categorized using the category field:
| Category | Description |
|---|---|
Created | Order was created |
Updated | Order was modified |
Canceled | Order was canceled |
Workflow | Workflow started or completed |
WorkflowStep | Individual workflow step executed (see Verbose Logging) |
Notification | Notification sent (email, SMS) |
Comment | Comment added to the order |
Error | An error occurred during processing |
Exported | Order exported to an external system |
Imported | Order imported from an external system |
Deleted | Order or related entity deleted |
Information | General informational event |
Published | Entity published |
Added | Item added to an entity |
BatchUpdate | Batch update operation |
BatchAdd | Batch add operation |
Each event includes contextual information such as the user who triggered it, the order status, shipment ID, market, store, and the origin of the action (API path, scheduled task, etc.).
