[Dragoljub Spasojevic]

It seems that in 6.3.3 are new OID for CPU/MEM usage.

Same OID on 6.2.3 these OID's works perfect.

hi Dragoljub,

it may be that reading from sysdb failed. There were some similar issues in the past. It would be the best to investigate this further through a TAC SR.

In general we recommend moving to Model Based Telemetry as opposed to polling via SNMP. Streaming telemetry not only performs better but also allows for monitoring of more parameters than supported by SNMP. If you didn't have a chance to see this Cisco Live talk, please try to find some time for it:

Hi Aleksandar,

I have upgraded to 6.4.2 and everything works fine. There is a problem with 6.3.3 definitely.
