What is Computer Monitoring?

Computer monitoring is the use of a system that collects all relevant data of a network's computers, analyzes it and ensures a proper working IT infrastructure. With computer monitoring the sysadmin can easily keep track of his whole network environment.

Be in control of your network computers

Damaged hard disks, connection failures, malware - hardware and software problems occur all the time in medium-sized companies.

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.

What kind of data is gathered?

Cpu utilization and operating temperature

An important part of computer monitoring is to keep track of the CPUs in your network. PRTG informs you about CPU Utilization, CPU temperature and performance. CPU monitoring helps you to identify possible problems before they become critical.


Memory usage

For peak performance of your entire network you have to monitor memory usage. With PRTG you are able to use preconfigured sensors like the WMI Memory Sensor, the SNMP Memory sensor or the SSH Meminfo Sensor. It's easy to keep track of your memory usage and avoid bottlenecks in your network with PRTG.


Bandwidth requirements

PRTG computer monitoring tracks your network bandwidth. With bandwidth monitoring you can measure the available bandwidth and real-time data such as download and upload speeds. Detect bandwidth overloads in an instant and prevent network strain.


Free hard disk space

Aborting installations, failing backups or disappearing user files - a common cause of such problems is a lack of disk space. Disk Space Monitoring is the solution for keeping the overview of your memory capacities. Use PRTG computer monitoring to visualize all memory capacities in one dashboard and ensure the smooth functioning of your business processes.


System information

PRTG computer monitoring is a great way to gather all the information about your IT infrastructure. System information is available for all devices you can add to PRTG. See details about a device such as connected hardware, installed software or running processes at a glance.

Your computers at a glance - even on the go
