Use SNMP version 2c For NetApp Monitoring
To our experience, a NetApp does not provide all counters via SNMP v1. This results in the error message quoted above.
In order to receive all counters in your NetApp sensors, please change the SNMP version from v1 to v2c. You can do this in the PRTG web interface in the Settings tab of the device which represents your NetApp.
Monitoring my NetApp with the provided SNMP Sensors i got the problem that only the SNMP I/O Sensor reports a failure: No such object (SNMP-Fehler # 222). All other SNMP Sensors are working right with the v2c Version.
