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 your all-in-one computer monitoring solution. 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.
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.

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

Computer monitoring FAQ
How does computer monitoring work?
During computer monitoring, data packets are sent to the monitoring tool where they are processed and analyzed. The data is sent via WMI, Flow technologies, or SNMP, depending on the manufacturer of the device that is being monitored. Many manufacturers use SNMP.
How can I prevent my computers from crashing?
If computers or the network goes down, company operations usually come to a standstill. Computer monitoring software with an alarm function ensures IT managers are immediately notified in the event of a major malfunction or disruption. Such software helps you prevent your computers and network from crashing.
How much does computer monitoring cost?
You can find everything from free computer monitoring software to tools that will run you several thousand dollars or euros per year. It all depends on your monitoring needs and the size of your network. PRTG offers flexible licenses so you can upgrade your monitoring as you please.
How can I monitor all the computers in my network?
It’s always a good idea to monitor all the main computers and devices in your network. By doing so, you’ll make sure your network runs smoothly. If an error occurs, you can immediately identify the cause. Computer monitoring software consolidates all monitoring data so you can monitor your computers from one central location.
How can I monitor the temperature on my computer?
Computers heat up quickly. At extremely high temperatures, they can even crash. Computer monitoring software lets you keep a constant eye on the temperature of your computers – even while on the go. You can therefore quickly take action if the temperature becomes critical.
