What is computer monitoring?

Computer monitoring is used to check the status of PCs and the programs that run on computers. Computer monitoring software consolidates all monitoring data into one central location. PRTG is a computer monitoring tool for sysadmins who monitor their network.

What is computer monitoring software?

A computer monitoring software like PRTG keeps track of all the computers of your network and prevents outages by sending early notifications in the event of errors or failures.










Manage your computer
with PRTG and prevent crashes

Damaged hard disks, connection failures, malware – hardware and software problems occur all the time in companies of all sizes.

There seems to always be a problem with at least one computer – much to the frustration of workers. IT support departments are responsible for tackling these issues and quickly limiting damage. But work interruptions ultimately lead to higher costs.

It is therefore a good idea to take precautionary measures instead of chasing problems as they arise. Central monitoring spots problems before they can happen and is quick to send alerts. PRTG is the all-in-one solution for your computer monitoring. Proactive administration leads to less lost data, minimal work stoppages, and happier workers.

With PRTG, you get full control of your computers of different producers like IBM, Dell, or HP. And that’s a great feeling.

Thanks to PRTG, the entire staff can work with peace of mind.


This is what our software for computer monitoring looks like



PRTG features a built-in system information overview for every computer in your network so you can keep abreast of all the important information concerning your devices. Besides, PRTG monitors your printers, data center, server rooms, or humidity and temperature. That's more than a standard monitoring tool can deliver. Along with other monitoring features which are already incorporated into PRTG, a comprehensive overview of your IT infrastructure and your network activity is yours to enjoy with just one single tool.

Computer monitoring even in distributed networks


Network and computer monitoring for businesses: 3 examples


Remote computer monitoring

The Student Hotel Group has over a dozen locations in Europe. All its monitoring data is sent to one IT location, including data on computers, servers, switches, bandwidth, and more. A separate remote probe was created in each location. “We tried other monitoring software but PRTG is the most user-friendly,” declares the IT manager. To the case study.  


Server room monitoring

The Concertgebouw is a famous concert hall in Amsterdam. Its IT managers monitor the temperature in the server room, as well as the website with its ticket system and many other devices. This monitoring saves the IT team lots of precious time. Discover the full case study here.


Tracking critical infrastructures

Jena University Hospital treats more than 300,000 patients per year in 26 different clinics. As a result, its network must always be up and running. This includes numerous computers and devices that are used for medical purposes. Thanks to PRTG sensors, the IT managers can keep a close eye on all the devices. To the case study.


PRTG PC hardware monitoring software features


Monitor PC temperature

Want to check the system temperature or the temperature of the CPU? You can monitor these values with our System Health sensors. Along with the CPU load, PRTG monitors the temperature and airflow of the devices in your network, making it the perfect tool for your server room.

Monitor PC capacity

How much of your memory and hard disks are being used? PRTG monitors RAM capacity and hard disk space. Thanks to its preconfigured sensors, your monitoring is set up in no time. And if memory is low, you’ll be alerted immediately so you can quickly redistribute your resources and prevent disruptions. 

Monitor bandwidth

Bandwidth bottlenecks make working on PCs nearly impossible. Most monitoring tools only check the Internet traffic on a single PC. But to uncover a bottleneck, you have to monitor the traffic in your entire network. 

More on bandwidth monitoring

Monitor PC traffic

What kind of traffic flows through your network? How much is web traffic and how much is mail traffic? What kind of files come from which IP addresses? PRTG provides for comprehensive traffic monitoring. Learn more about SNMP monitoring, flow monitoring and packet sniffing with PRTG.

And much more

PRTG comes with 250 preconfigured sensors for monitoring your hardware, applications, traffic, and more.

Practical tip: “Hey Stephan, what would you tell administrators looking to set up CPU monitoring with PRTG?”

“The SNMP CPU Load Sensor is a great way to get a handy overview of the load on all of a host’s CPU cores with just one sensor. Of course, this sensor also displays the total CPU load, which means you can always tell right away if one of your server’s processors is about to reach its load limit!”

Stephan Linke, technical support at Paessler AG
