The idea of this item prototype template is to create item that preforms check once per month., but the discovery item cannot create items by such prototype with flexible intervals where interval time = 0. Instead it reports `Cannot update item: Invalid flexible interval "0".` when according to docs it should able to do so: "If the flexible interval is set to '0', the item is not polled during the flexible interval period and resumes polling according to the default Update interval once the period is over."
