Problem 

User wants to Monitor Linux with SNMPD but HOST-RESOURCE-MIB is not loaded properly and cannot monitor disk / memory usage

Solution

replace the content of /etc/snmp/snmpd.conf

#agentAddress udp:161,udp6:[::1]:161

com2sec monitor 10.0.0.100 COMMUNITHY
com2sec notConfigUser default public

group notConfigGroup v1 notConfigUser
group notConfigGroup v2c notConfigUser

view systemview included .1.3.6.1.2.1.1
view systemview included .1.3.6.1.2.1.25.1.1

access notConfigGroup “” any noauth exact systemview none none

syslocation New York
syscontact Root <root@localhost> (configure /etc/snmp/snmp.local.conf)

dontLogTCPWrappersConnects yes
rwuser opmanager

mibdirs /usr/share/snmp/mibs/
mibs HOST-RESOURCES-MIB
