[rrd-users] All NaN - what am I doing wrong

I am trying to collect memory stats for the MRTG server that is running
Net-SNMP. The following is my configuration. All I get returned is NaN on
the .rrd file. I can get the correct value doing snmpget for the OIDs. The
value returned is of type Integer so I added gauge to the Options line.

I tried experimenting with rateup to see if it is an issue with RRDTool but
all I got in the .log file is the first value and the rest are zeros.

Can someone let me know what am I doing wrong?

Collection of stats works fine for CPU (totcpu).
