Just for know:

 HOST-RESOURCES-MIB::hrProcessorLoad == .1.3.6.1.2.1.25.3.3.1.2
 UCD-SNMP-MIB::laLoad                == .1.3.6.1.4.1.2021.10.1.3

Load average is not CPU usage, this metric is old as UNIX:

Observium is polling the hrProcessorLoad, right?

If run that manually i'm getting exactly what is Observium graphing (when i'm interpreting that correctly) - 3 cores at 100

root@observium-ce:~# snmpwalk -v3 -l authPriv -u xxx -a SHA -A xxx -x AES -X xxx 127.0.0.1 HOST-RESOURCES-MIB::hrProcessorLoad
HOST-RESOURCES-MIB::hrProcessorLoad.196608 = INTEGER: 100
HOST-RESOURCES-MIB::hrProcessorLoad.196609 = INTEGER: 100
HOST-RESOURCES-MIB::hrProcessorLoad.196610 = INTEGER: 5
HOST-RESOURCES-MIB::hrProcessorLoad.196611 = INTEGER: 100
root@observium-ce:~#

versus:

root@observium-ce:~# snmpwalk -v3 -l authPriv -u xxx -a SHA -A xxx -x AES -X xxx 127.0.0.1 .1.3.6.1.4.1.2021.10.1.3
iso.3.6.1.4.1.2021.10.1.3.1 = STRING: "0.05"
iso.3.6.1.4.1.2021.10.1.3.2 = STRING: "0.07"
iso.3.6.1.4.1.2021.10.1.3.3 = STRING: "0.13"
root@observium-ce:~#

top - 22:42:48 up 1 day,  2:45,  2 users,  load average: 0.05, 0.07, 0.13

Still confused... the LXC Container im running Observium on and polls
itself via SNMP has 4 cores assigned where 3 cores are graphed at 100%
all the time since the container is turned on - and it's now
explicitly the only Container/VM running on this hardware.

But if i manually run following SNMP query on the LXC Container i get
the same values as TOP shows for 1/5/15 minutes:

root@observium-ce:~# snmpwalk -v3 -l authPriv -u xxx -a SHA -A xxx -x
AES -X xxx 127.0.0.1 .1.3.6.1.4.1.2021.10.1.3
iso.3.6.1.4.1.2021.10.1.3.1 = STRING: "0.09"
iso.3.6.1.4.1.2021.10.1.3.2 = STRING: "0.06"
iso.3.6.1.4.1.2021.10.1.3.3 = STRING: "0.07"
root@observium-ce:~#

top - 22:17:18 up 1 day,  2:09,  2 users,  load average: 0.09, 0.06, 0.07

This doesn't match what is graphed for the CPU cores in Observium

There's no difference to how the two versions operate when polling these
things.

We can only show the data that the SNMPd provides to us. If the number being
returned is an instantaneous value instead of a 5 minute average, the act of
polling itself will affect the value.

But if you don't poll it, is it even turned on?
