What is hardware scanning?


Hardware scanning is crucial to your infrastructure organization – it’s knowing what hardware you have and if it is functioning correctly. A hardware scanning tool will also tell you when your hardware has failed or is about to fail.

Why do we need hardware scanning?

Hardware is the first layer in an infrastructure organization – if that fails, then everything else from the servers, to the operating systems, to the applications and the processes fail. Your hardware has multiple possible points for failure and it is too important to reply on a human to check it. Having a monitoring system that scans your hardware at regular intervals is crucial to the survival of your organization. 

Pros to having a hardware scanner:


  • Real time status of your hardware
  • Ability review trends from historic data
  • Ability to react quickly in an emergency
  • Scan both health of the hardware and its performance

Keep a constant eye on your network
– even while on the go

PRTG monitors these vendors and applications, and more, in one view!


Different sensors


iWhat is a sensor?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.

PRTG uses sensors to scan or poll your devices through a specific protocol to gather the relevant data. PRTG has multiple vendor specific hardware sensors out of the box that covers monitoring of system health as well as individual components. In addition, we have generic SNMP and WMI sensors. PRTG also allows for the importing of MIB files to extend beyond our out of the box offerings so that additional hardware may be scanned by PRTG. 

System health sensors

PRTG includes system health sensors for

These sensors have multiple channels to give the hardware status of several components within your device or server. 



SNMP Hardware Status Sensor

There is also a generic SNMP Hardware Status that can scan and monitor individual components through SNMP if none of our vendor specific sensors match your hardware. 

Several disk sensors

PRTG also includes several vendor specific individual disk sensors such as

as well as several others. 

WMI Vital System Data (V2) Sensor

With the WMI Vital System Data (V2) Sensor PRTG can monitor the performance of your vital system parameters.  It can gather metrics such as CPU usage (processor, privileged, user time and queue length), memory (page faults, reads and writes per second as well as committed bytes), and physical disk (time in percent, reads/writes per second and queue length).

SNMP Printer Sensor

PRTG can also monitor your SNMP-enabled printer – it can even alert you when your toner is low!

Additional PRTG features


You can even get more detailed hardware scanner information by importing your MIB files into PRTG – you can select all or individual OIDs to get granular monitoring on your hardware!

You can see the full list of our Hardware Parameter Sensors here. 

PRTG offers real time notifications so when components are non-responsive or hit a defined threshold that you set you can be made aware of it as soon as possible. PRTG also has the ability for you to create custom maps/dashboards and reports on your hardware sensors so when your hardware is scanned you can view the data in a variety of ways.
