Hi everyone,
I'm currently monitoring a Cisco Catalyst 9200 switch running IOS XE 17.12.x using PRTG via SNMPv2.
SNMPv3 is also configured and used for other monitoring purposes.
Basic sensors like ping, uptime, CPU, and memory are working fine. However, system health-related sensors such as temperature, voltage, current, etc. are returning errors like "No data" or "No such object (SNMP error #222)".
The SNMPv2 community string is correctly configured and working.
Older Catalyst 9200 switches running IOS XE 17.09.04a are being monitored successfully with the exact same SNMP configuration.
Please help me find a solution to make SNMPv2 monitoring of system health sensors work properly on the newer switch.
Thank you in advance.

I think OID is change
Check
snmpget -v2c -c public <switch-IP> <OID>
To see if it available or not

- @TrangLeHuynhThien7790 You should indeed verify the SNMP OID used by using a a 'manual snmpget' and try them out; in case PRTG is using the wrong ones ; sometimes they change between versions too (a little bit)

Once you know which MIBs your PRTG is trying to query, this might also help you to look up what exactly is supposed to be behind this MIB and navigate through the OID tree:
