getAssociatedMonitors request isMultiple field meaning
In the attached image there is an instance of a api/json/device/getAssociatedMonitors? request for one of the default monitors available in OpManager.
I need help identifying the "isMultiple" field meaning, why is this field varying its value from one monitor to the next? Is it related to the "data" field availability and why is it unavailable in some monitors?
Thank you in advance.
