I'm testing now PRTG. We have few firewalls (pfsense) sending Syslog to PRTG. I'm creating a syslog server sensor per device and is working well.
One of the requirements that we have is to see source country for each user connected to our OpenVPN server running on pfsense.
Do you have any filter, map or other ideas to visualise the source country for the OpenVPN users? We can do it via syslog or snmp.
