　　Disk Statistics
　　The snmpd.conf needs to be edited. Add the following (assuming a machine with a single ‘/’ partition):
　　disk / 100000 (or)
　　includeAllDisks 10% for all partitions and disks
　　The OIDs are as follows
　　Path where the disk is mounted: .1.3.6.1.4.1.2021.9.1.2.1
　　Path of the device for the partition: .1.3.6.1.4.1.2021.9.1.3.1

　　Total>　　Available space on the disk: .1.3.6.1.4.1.2021.9.1.7.1
　　Used space on the disk: .1.3.6.1.4.1.2021.9.1.8.1
　　Percentage of space used on disk: .1.3.6.1.4.1.2021.9.1.9.1
　　Percentage of inodes used on disk: .1.3.6.1.4.1.2021.9.1.10.1
　　System Uptime: .1.3.6.1.2.1.1.3.0
　　python snmp 从OID获取对应的值
　　先安装模块 netsnmp
import netsnmp　　
session = netsnmp.Session( DestHost='your.host.com', Version=2, Community='public' )
　　
vars = netsnmp.VarList( netsnmp.Varbind(oid) )
　　
print( session.get(vars) )
