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

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) )
