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.

Can you explain what you mean with

There's CPU Load & Memory usage, but is there a particular sensor 
that can report back "Device at X% utilization" ?

...in a more detailed way? Do you mean like a health state that combines the state of ram, cpu and storage usage?

Hello,

I'm trying to establish a baseline for the device, and need bandwidth (which I monitor using the SNMP Traffic sensor) and a sensor for "health" (CPU/Memory/Disk). Basically I need to see if our devices are overloaded, either from network utilization or from hardware utilization.

We don't have health sensors for all devices. When you filter the "Add sensor" page (where all the sensors are shown) for "health", it lists quite a lot of health sensors for various devices. Maybe the right one for you is among them?

If not, you basically want all data within one graph and then see what it looks like when the device is under average load so you can determine at what point you need to interfere? The sensor factory sensor might be just the thing for you. You can add the various channels from those sensors into one sensor, giving you a complete graph :)
