Hello,
On all of my Debian Bullseye devices SNMP data concerning Processor usage, Memory usage etc are missing.
I have installed SNMP (as it is not installed by default), is active and works but LibreNMS only gets very succint results. 90% of the data are missing.
The Poller has plenty of SNMP-FRAMEWORK-MIB::snmpEngineTime.0 = No Such Object available on this agent at this OID
See here : Untitled - LibreNMS
./validate.php

Devices equipped with Debian Buster are generating all the data LibeNMS needs in order to generate the correct graphs and data.
Can anybody help, please. I’m running in circles 
Thank you for your help.
