# Filter events

To enhance focus on critical tasks and reduce unnecessary data processing within Data One (i.e. Data Mover in a bundle with Data Watcher), specific events that should not be transmitted can be filtered.

This can be achieved by configuring a particular property designed to selectively prevent the forwarding of events associated with designated service tasks to Data Mover and Data Watcher.

Follow these steps to set up event filtering:

1. In Data One, go to **Setup** → **Advanced Settings**.
2. Click on the **NEW** button in the top-right corner of the screen.
3. Enable the **Click to add a new module/section** toggle.
4. In the **Module** field, enter **workflow**.
5. In the **Section** field, enter **logging**.
6. In the **Property Name** field, type **workflow\.logging.hide.dw\.event**.
7. In the **Property Value** field, enter the **Model Ids of the service tasks that should not be sent to Data Watcher**, separated by a semicolon (;). Here is an example: bpmEventNotificationService;bpmGetMetadataService;bpmSetGenericMetadataService;bpmVirtualPathFromString;bpmVirtualPathToString\
   The Model Id of each service task is available on the [Standard Service tasks](/data-mover-1.21/workflow-templates/service-tasks/standard-service-tasks.md) and [Triggerable service tasks](/data-mover-1.21/workflow-templates/service-tasks/triggerable-service-tasks.md) pages. 
8. Click **CONFIRM** to save.

The new property will be **applied immediately**. You do not need to restart the CEMAN.
