This field is automatically included in all reports. It is not an option that can be selected from Reported fields during template creation. This field displays the timestamp of the last time the server received counters and consumables information from the device. This field is affected only by counters and consumables updates, and by settings entered in group management. Updates can be as frequent as four times a day depending on the settings.
The “filtered“ counter takes into account any counter drops which may have occurred and removes them (in case counter is reset).
The ”unfiltered” counter will keep data regardless of whether it has dropped.
