SNMP CPU memory OID

Here is a sample structure of an OID

Iso (1).org(3).dod(6).internet(1).private(4).transition(868).products(2).chassis(4).card(1).slotCps(2)

.cpsSlotSummary(1).cpsModuleTable(1).cpsModuleEntry(1).cpsModuleModel(3).3562.3

Most of the people may be looking for OID’s for Linux OID’s for CPU,Memory and Disk Statistics for this first you need to install SNMP server and clients. If you want to install SNMP server and client installation in linux check here

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
