All of the datums for the most recent reading of the sensor device, separated by commas, in textual format. For example, a report for a temperature and humidity sensor might read '20.3, 35' indicating 20.3 degrees at 35 percent humidity. If only one datum is reported by a sensor device, e.g. for a simple temperature sensor, it will be reported singly with no commas. The use of this OID is recommended for most users, rather than the single value ones, because all values can be retrieved atomically from a sensor in one SNMP request.
