PRTG Network Monitor: perfectly customizable hardware monitor


Hardware monitoring begins with a simple ping test: PRTG monitors your hardware and checks to make sure all servers work and computers are accessible. If the ping test fails, the device is either switched off or the problem lies with a cable that is damaged or not plugged in, or else with a faulty internet connection.

PRTG provides an alert as soon as a ping test fails, and lets you fix network and hardware problems on the spot.

Of course, PRTG monitors the status and properties of all your hardware of different producers like IBM, DellCisco, Synology or LinksysIt additionally gives you a system information overview for every device. 

 i Ping is a command-line utility, available on virtually any operating system with network connectivity, that acts as a test to see if a networked device is reachable. The ping command sends a request over the network to a specific device. A successful ping results in a response from the computer that was pinged back to the originating computer.

Hardware monitoring with PRTG

 i How PRTG defines sensors

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.

CPU and RAM Monitoring

CPU and RAM Monitoring

PRTG monitors your CPUs and memory capacities at a glance. The monitoring tool alerts you ahead of time if there are any issues with loads, the hardware's temperature, or any other failures.

Hard drive monitoring

Hard drive monitoring

PRTG provides an alert if the amount of free disk space becomes too low, records changes in data, and can even determine if a certain file is available. Data losses are avoided. And hard drives can quickly be replaced or supplemented. Even NAS systems and storage area networks (SANs) can be monitored.

Printer monitoring

Printer monitoring

Our hardware monitor also monitors network printers. You not only obtain information regarding the printer's accessibility, but also information on the cartridge's ink level, the number of printed pages, and whether any specific error messages have appeared.

Router and switch monitoring

Router and switch monitoring

PRTG monitors network hardware (routers, switches), as well as everything else of interest to administrators, such as network traffic, software, and websites. You thereby learn which devices, programs, or users produce the most traffic in your network, or where in your network shortages occur.

All Other hardware and devices

All Other hardware and devices

PRTG can monitor any other computer and devices which support SNMP. Our API and custom sensors are available for your individual monitoring setup. In addition, PRTG performs the monitoring of environmental settings, such as temperature monitoring and humidity inside your server rooms.

3 good reasons to choose PRTG as your hardware monitor

More stable work processes with hardware monitoring

Hardware always seems to stop working when you need it the most. At critical moments, such as just before a deadline, productivity losses can be very costly and result in contractual penalties. Data plays an increasingly vital role in your business. This means that when losses in data occur, you feel it that much more.

PRTG lets you act
before problems occur

PRTG alerts administrators if the system is at risk: before the memory overloads, before the printer runs out of ink, and before the router fails. Nevertheless, IT professionals should not have to be concerned with the status of hardware any more than is necessary. Hard drives should function smoothly, printers must be ready, and all devices are to run reliably. PRTG takes care of all of this. Our hardware monitoring software makes life easy for administrators by running dependably in the background.

Thanks to PRTG, work process disruptions and sales losses can be avoided.

With PRTG, everyone in the office can rest assured

IT professionals are forced to resolve many issues within strict time constraints and an IT environment which is becoming more and more complex. PRTG automates routine tasks. After all, you already have enough on your plate. Hardware monitoring does not have to make things more difficult.
