I am trying to add a monitor to a device template.  The MIB for the monitor in question references an index value.  There are multiple sensors of the same type, in this case temperature sensors for an APC UPS.  To get data for a specific sensor, I need to reference the index value of the probe in the OID.  How do I change the SNMP OID value for the monitor to add an index?

 

Thanks in advance for your assistance.
