Our apologies for the late reply. We have gone ahead and added a new query parameter alarmsinfo_required in current_status api. By passing "alarmsinfo_required=true", you will get a new attribute in response called "technician", which is the ZUID of the User who has acknowledged the alarm. If the alarm is not acknowledged, "technician" attribute will not be present for that monitor. Based on that you identify the monitors which are acknowledged and which are not.
