The OID represents either the object identifier to request on host, or to match in traps that are received. The Data type is the Mango representation of the value. Received data is automatically converted to the required data type. The Binary 0 value is the value to match for a binary point to be given the value 0. The Set type is the SNMP data type to use when setting values on the host. A value of "(not settable)" indicates that the point is read-only. The Polling field determines whether to include the value in GET requests with each polling cycle, or whether values are received only via traps.
