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

#snmpget -v 1 -c “community” target_name_or_ip .1.3.6.1.4.1.2021.10.1.3.1
Get the 5-minute system load on the target host
#snmpget -v 1 -c “community” target_name_or_ip .1.3.6.1.4.1.2021.10.1.3.2

Get the 15-minute system load on the target host

#snmpget -v 1 -c “community” target_name_or_ip .1.3.6.1.4.1.2021.10.1.3.3

Get amount of available swap space on the target host

#snmpget -v 1 -c “community” target_name_or_ip .1.3.6.1.4.1.2021.4.4.0
