Im using net-snmp-5.2.1 with mrtg on a Alpha CPU.

I want to monitor my memorry usage. However when I add the following to 
the mrtg.cfg file I find that SNMPD shuts down and I get these errors in 
the logs.

I add this to mrtg.cfg

LoadMIBs: /usr/local/share/snmp/mibs/UCD-SNMP-MIB.txt

### Memmory

Target[freemem]:. at localhost
Options[freemem]: nopercent,growright,gauge,noinfo
Title[freemem]: Free Memory
PageTop[freemem]: <H1> Free Memory </H1>

YLegend[freemem]: bytes
ShortLegend[freemem]: bytes
LegendI[freemem]:  Free Memory:
Legend1[freemem]: Free memory, not including swap, in bytes

I get this in the snmpd.log file

kvm_openfiles: Permission denied
kvm_openfiles: /dev/mem: Permission denied

I do see the file in /dev/mem

ls -la mem
crw-r-----  1 root  kmem    2,   0 Jan  6 17:45 mem
