Redhat 7.1 & mrtg reporting free memory...

[jeremyfo]

I'm having a problem getting mrtg in RedHat 7.1 to report freemem. Here is my configuration

Target[freemem]:.1.3.6.1.4.1.2021.4.11.0&.1.3.6.1.4.1.2021.4.11.0ublic@xxx.xxx.xxx.xxx
Options[freemem]: nopercent,growright,gauge,noinfo
RouterUptime[freemem]: public@xxx.xxx.xxx.xxx
Title[freemem]: Free Memory
PageTop[freemem]: <H1>Free Memory</H1>
MaxBytes[freemem]: 512904
kMG[freemem]: k,M,G,T,P,X
YLegend[freemem]: bytes
ShortLegend[freemem]: bytes
LegendI[freemem]: Free Memory:
LegendO[freemem]:
Legend1[freemem]: Free memory, not including swap, in bytes

However, when i run

$ snmpwalk localhost public .1.3.6.1.4.1.2021.4.11.0
enterprises.ucdavis.memory.memTotalFree.0 = 1100148

I get the correct response, However, mrtg will not graph it and it records 0 in the logs?

Any help would be appreciated. Everything else I'm logging seems to be working correctly.

Thanks
Jeremy
