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 從OID獲取對應的值
先安裝模塊 netsnmp
import netsnmp session = netsnmp.Session( DestHost='your.host.com', Version=2, Community='public' ) vars = netsnmp.VarList( netsnmp.Varbind(oid) ) print( session.get(vars) )
