解决办法：
1. Install snmpd :apt-get install snmpd
2. Ensure the multiverse repository is enabled :
apt-get install python-software-propertiesadd-apt-repository 'deb http://archive.ubuntu.com/ubuntu precise multiverse'apt-get update3. Install the snmp-mibs-downloader :apt-get install snmp-mibs-downloader
4. Edit/etc/default/snmpdand setMIBS=UCD-SNMP-MIB(this is the key fix)
5. Restart snmpd :/etc/init.d/snmpd restart
