I´m trying to set the SNMP Memory for Linux (Ubuntu) but when I finish to setting I got that error.
I followed this step: 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. For a general introduction to the technology behind SNMP, please see the manual section Monitoring via SNMP.
But anything happen.
Could you give me somo hints?
