The drift detection scan runs periodically, according to the interval set in the definition. (The default is 1800 seconds, or 30 minutes.) There can be times when you know that files in the directory have changed and you need a snapshot to be created immediately, but you do not want to change the interval permanently. Simply run a detection scan manually.
Click the Inventory tab in the top menu.
Search for the resource.
Click the Drift tab.
Select the drift definition to run the scan for.
Click the Detect Now button.
