Computer monitoring: FAQ


1. 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 monitored device.

2. Which computer manufacturers does PRTG support?

PRTG has no vendor lock-in. It can monitor all computers and devices that support SNMP or other standard protocols and technologies. For more convenience, it comes with preconfigured monitoring sensors for the most common manufacturers such as Dell, HPE, and more out-of-the-box.

3. How can I prevent my computers from crashing?

If computers or the network go down, company operations usually come to a standstill. Computer monitoring software with a customizable alerting system, like PRTG, 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.

4. How much does computer monitoring cost?

You can find everything from free computer monitoring software to tools that will cost 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.

5. How can I monitor all the computers in my network?

Monitoring your entire network of computers with PRTG is as easy as ensuring your target system supports SNMP and has it enabled. After allowing access to PRTG, the computers are shown in the central dashboard, providing a comprehensive overview of your system.

6. How can I monitor the temperature on my computer?

Computers heat up quickly. At extremely high temperatures, they can even crash. PRTG computer monitoring software lets you keep a constant eye on the temperature of your computers – even while on the go with the mobile app. This makes it easy to quickly take action when temperatures spike unexpectedly.

7. What is a sensor in PRTG?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive.

On average, you need about 5-10 sensors per device or one sensor per switch port.
