Cisco CPU/MEM monitoring

Running NagiosXI 2024R2.1 in Azure cloud. Having issues with getting cpu/mem data from my switches. Router/Switch wizard gives me ping and Interface status/utilization but does not provide CPU or Mem utilization the I can see. i have tried several plugins for snmpv3 (and just to test I also configured a snmpv2c test which completely failed :shock: ) including:

check_snmp_load.pl
check_cisco_status.pl
check_snmp_load_wizard.pl

For check_snmp_load.pl this was my config:

-H x.x.x.x -l snmpuser -x <authpass> -X <privpass> -l md5,aes -w 75 -c 90 -T cata -t 30

I have configured the command against each of these plugins and I run the check on the command all I get back is "3 warnings and a critical" as a response. At this point I am not sure what I can do next. Is anyone currently monitoring CPU/MEM usage on Cisco switches using NagiosXI and would you care to share your process.
TIA
Bill

Is there an OID for those metrics?

If there is an OID for this you could try SNMP walk wizard.

SNMP Walk would work, or if you do find just those OIDs and maybe the SNMP Walk wizard returns a ton of stuff, you could also try just the SNMP wizard.
