While you can always perform individual device rediscoveries on demand (see the Rediscover option in Assets Reports Actions), you can also schedule rediscoveries that occur:
Scheduled rediscoveries provide critical asset change information that you can report upon, then present to your customers as validation of your asset management services. That information can also suggest further, revenue-generating services that you can sell.
From the Assets category page click on the Schedule Rediscovery (One Time) link to display the Schedule One Time Rediscovery form.
Select the Schedule Once radio button, then select the desired month, day, year and AM/PM from the drop-downs.
Enter the desired time of day into the at field.
To limit the collected information to just newly-discovered systems information, leave the Asset Inventory Only checkbox selected.
If you make a mistake and wish to start again, click on the Reset button.
Click on the Save button to schedule the rediscovery.
Or, click on the Cancel button to abandon the operation.
To cancel a scheduled rediscovery, click on the Don't Schedule checkbox.
