I'm new to PRTG and have taken on an existing setup. Our equipment has been discovered ok but PRTG only seems to be a PING Sensor being used with each router. How easy is it to add a Bandwidth monitoring sensor for a specific port, to see how much usage the link has? I tried to right click, add sensor. I clicked Monitor Traffic/Bandwidth, but it then says Target System Type. I can't see any option for Router/Switches. Only says Windows, File server etc.. I guess I'm doing this wrong. Basically all I want to do is check link usage on a specific port on a router.
