I have setup a new Probe server. On the probe server I am monitoring 10 Windows 2016 servers, each server has 5 sensors. I have installed the syslog receiver onto the Probe Device. When I go into the probe device and click on syslog server I see no messages coming through. I then removed the syslog receiver from the Probe Device and installed it on one of the servers in PRTG, I went into syslog and still see nothing. I watched the PRTG video on installing and configuring a syslog server but am not sure what else to check. Do I need something installed on the windows servers like an agent?
