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 size of the disk/partion (kBytes): .1.3.6.1.4.1.2021.9.1.6.1
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
Examples
These Commands you need to run on the SNMP server
Get available disk space for / on the target host
#snmpget -v 1 -c “community” target_name_or_ip .1.3.6.1.4.1.2021.9.1.7.1
this will return available disk space for the first entry in the ‘disk’ section of snmpd.conf; replace 1 with n for the nth entry
Get the 1-minute system load on the target host
