something is not quite right with the autodiscover process.
I just installed 2 HP proliant dl 360 G7 machines with windos 2008 r2 and for some reason the autodiscover process thinks it should add a sensor of type ciscoswitch, reporting free memory of 5 kb ?
I have no clue where the 5kb comes from, or even why it thinks it should add a cisco type sensor. We don't even run cisco devices on the lan to which PRTG is installed.
Anyway, version I'm running it 184.108.40.2066 but I have found no mention of these issues in the release notes that have come out and are available on the paessler website (https://www.paessler.com/prtg/prtg9history)
