I'm trying out PRTG's 1-month trial and so far I have been very happy with it. I'm still figuring it out the UI and everything, but so far I've set up sensors on the switch ports I'm interested in and have been getting some good results.
My question now is, is there any one sensor that can monitor switch (or device, like firewall for example) utilization ? There's CPU Load & Memory usage, but is there a particular sensor that can report back "Device at X% utilization" ?
Afterwards, is there a way to report that in the graph ? I only see Alarms, Response time index, CPU Load and Traffic - and I'm currently only using traffic sensors, so nothing else is showing up.
