Sensors in the Dagster UI

Now that the sensor is built, let's take a look around the Dagster UI.

Step one

Navigate to the Global Asset Lineage page, where you should see the new asset, adhoc_request.

Note: If you don’t see the asset, click Reload definitions first.

Step two

Click Overview > Sensors. In this tab, you’ll see the adhoc_request_sensor.

Notice that the Running toggle button has the sensor marked as turned off. By default, all sensors and schedules are off when first loaded.
