You can add the primary probe column in the ADT tables, and the probe with its polling frequency can be executed periodically. The probe will trigger the configured intents in the same row when it creates any alert. Configuring the primary probe involves the following steps:

1. Go to preventive automation via ADT tab and install an automation item as detailed in Preventive Automation via ADT.
2. Select the installed automation item and its primary probe configuration pane will appear at the bottom of half of the Preventive Automation via ADT tab. 
3. Click on Select Probe and select the Probe column defined in the ADT as the trigger source. For instance, select Probe.




4. Select the XX/XX probes enabled and select the check box of all the required probes.

The probe in the ADT may be in disable status, and the screen here shows number of probes in enabled status out of the total probe count. You can enable some or all probes based on your use case.

For example: 43 out of 61 probes enabled as shown in figure.

5. You can adjust the frequency individually for each probe or apply same frequency for all probes at once. And then click Save.




6. The intent execution rules for Primary probe are same as the Looking Glass Probe except the primary probe do not have the option to select secondary probes.

Refer to Configure Intent to be Triggered  and Last Resort Timer for more detailed information.
