Automatic probes are executed by the Asset Discovery background process, no matter if you are logged on at the hosting machine or not. That's the normal mode of operation for OT-BASE Asset Discovery in production use; you will use manual probing only when setting up a new Asset Discovery node.
Activating automatic probing
In order to configure automatic probing, select the Asset Discovery node object. In the details pane, check the box in the "Active" field. In the field below, you can specify a time for scheduled probing. Note that the time is specified in 24-hour-format, so for example 3:00 p.m. would be entered as 15:00. Probing/exporting will be done every 24 hours.
Check the "Export" box for every network that you want to probe
Automatic probing will only be done for networks that have their "Export" box checked. Therefore, select every network that you want to probe automatically and check the "Export" box in the network details pane. Networks that are checked for export (and therefore also for automatic probing) will be shown in green in the object table.
