I have a simple custom SNMP OID sensor setup that returns the error
- N SNMP_EXCEPTION_NOSUCHINSTANCE223
When I do an snmp walk for that OID it returns the proper value ( 1)
~ user1$ snmpwalk -v2c -c mypassword 192.168.2.3 188.8.131.52.4.1.254184.108.40.206.5.1.3 SNMPv2-SMI::enterprises.254220.127.116.11.18.104.22.168 = INTEGER: 1
The Sensor is added to an existing device that has many other sensors which work fine so the community and permissions are correct.
