Setting up PRTG from scratch and have most everything working, but trying to set up SNMP trap collection on PRTG. Installed the SNMP Trap Receiver on the probe device, no modifications to it at all (using default settings). Using snmptrapgen to send the trap to the PRTG system (same subnet - starting small) and I see the traps coming into the OS where PRTG is installed (windows 10) . Using SNMP v2c, trap comes in that way with a valid OID. The sensor sees teh messages (i see it in the live data as the counts are non-zero for the time intervals I send test traps) and I can see them come in via Wireshark on the PRTG box. So why are there no messages?? The filter is set to "any" (the default) so I assume I would have processed it. Nothing in the logs tab to give me any clues.
