对应字符串是hrProcessorLoad

UCD-SNMP-MIB::memAvailSwap.0 = INTEGER: 284752 kB


Total RAM in machine snmpwalk -v 1 -c public localhost .1.3.6.1.4.1.2021.4.5.0
UCD-SNMP-MIB::memTotalReal.0 = INTEGER: 255672 kB


The available real memory snmpwalk -v 1 -c public localhost .1.3.6.1.4.1.2021.4.6.0
UCD-SNMP-MIB::memAvailReal.0 = INTEGER: 14456 kB


the Total free memory in the machine (free Swap memory free RAM memory)

snmpwalk -v 1 -c public localhost .1.3.6.1.4.1.2021.4.11.0
UCD-SNMP-MIB::memTotalFree.0 = INTEGER: 298804 kB

UCD-SNMP-MIB::memCached.0 = INTEGER: 47816 kB

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
