Hello Team,
We would like to monitor the linux machine system load using nagios SNMP, please let us know if there are any plugins to monitor the same.
Note : We already using SNMP monitoring for linux machine monitoring which includes CPU load, disk and services monitoring.

Are you looking for the load average then? Can you show us the full output of a snmpwalk against the machine? snmpwalk -v 2c -c <communitystring> <iphere>

I can't seem to pin point the specific MIB that would resolve to the OID here, and from what I can tell - nothing seems to look like one resembling to load avg. Do these OID's provide the information you're after?
Code: Select all
1 minute Load: .1.3.6.1.4.1.2021.10.1.3.1
5 minute Load: .1.3.6.1.4.1.2021.10.1.3.2
15 minute Load: .1.3.6.1.4.1.2021.10.1.3.3

[root@swnagios tmp]# snmpwalk -v 2c -c public 10.7.1.183 .1.3.6.1.4.1.2021.10.1.3.1
UCD-SNMP-MIB::laLoad.1 = STRING: 0.47
[root@swnagios tmp]# snmpwalk -v 2c -c public 10.7.1.183 .1.3.6.1.4.1.2021.10.1.3.2
UCD-SNMP-MIB::laLoad.2 = STRING: 0.49

Awesome - what you'll want to do now is run through the SNMP walk wizard.
When it asks for the base OID / MIB on the first page to use, enter .1.3.6.1.4.1.2021.10.1.3 - on the second page, you should see at least the 3 OID/MIB's populated with the data. This wizard will allow you to specify your thresholds as well so that you can have the state change should a spike occur.
