Trying to monitor bandwidth on a external IP Sonicwall. SNMP has been enabled on the Sonicwall via the Interface and SNMP configuration under system.
Using SNMP Traffic Monitoring sensor. This device is outside of the local network. Using the PRTG testing tool failed as well.
Here is the error -
Sensor does not get response from device. SNMP credentials are wrong or device does not support the required uptime OID (188.8.131.52.184.108.40.206.0) for traffic sensors. This OID is mandatory by the SNMP RFC. Check SNMP access rights or contact device vendor. (code: PE244) Please check the following resources:
You can define the displayed sensor name with port name templates in the SNMP Compatibility Options of the parent device. We recommend that you choose SNMP v2c (most common) or SNMP v3 in the Credentials for SNMP Devices of the parent device (if supported by the device that you monitor). SNMP v1 does not support 64-bit counters which may result in invalid data. For details, please see the Knowledge Base: Querying 64-bit Counters with SNMP Traffic Sensors It might not work to query data from a probe device via SNMP (querying localhost, 127.0.0.1, or ::1). Add this device to PRTG with the IP address that it has in your network and create the SNMP sensor on this device instead. Knowledge Base: How do PRTG's automatic port name and number updates work for SNMP traffic sensors? Knowledge Base: Where is the volume line in graphs? For a general introduction to the technology behind SNMP, please see the manual section Monitoring via SNMP.
