I'm having a heck of a time trying to get an SNMP Library sensor to install for a specific device. I've used the Paessler SNMP Tester (version 20.2.4) and adjusted the device's SNMP and security settings to allow the tester to pull basic data like Device Uptime as well as walking through part of the OID hierarchy from the device's MIB/OIDLIB file, but when I attempt to install the Library sensor using the PRTG Desktop and selecting the OIDLIB file created from the Paessler MIB Importer (version 3.5.8) the sensor creation fails with "Error connecting device. Check IP, Port, Community!"
Not sure how to further troubleshoot this. One thing I notice is there's nowhere to input the device's community string, so I set it to generic "public" on the device with READ ONLY rights and use the public community name when using the tester.
Thanks for any suggestions.
