How to set up PRTG free bandwidth monitoring with 100 sensors

3 tips for setting up PRTG monitoring

test

Start big

The PRTG Auto-Discovery function is launched upon installation. It searches for available devices within a certain range of IP addresses and sets up an initial monitoring environment. This facilitates the configuration and maintenance of your monitoring.

test

Narrow down

With the 100-sensor edition of PRTG, you’ll have to delete most of the sensors created by the automatic network discovery. For basic monitoring, use most of your sensors for essential servers, routers, and switches.

Free Bandwidth Monitor: FAQ

 

What is bandwidth?

Bandwidth is measured as the amount of data that can be transferred from one point to another within a network in a specific amount of time. Typically, bandwidth is expressed as a bitrate and measured in bits per second (bps). It refers to the transmission capacity of a connection and is an important factor when determining the quality and speed of a network.

What is bandwidth monitoring?

Bandwidth monitoring is the process of tracking and analyzing the amount of data transmitted over a network connection within a specific period. It helps administrators understand the usage patterns, identify potential bottlenecks, and optimize network performance. By monitoring bandwidth usage, organizations can allocate resources effectively, detect unusual activity or unauthorized usage, and plan for capacity upgrades as needed.

Is PRTG for free?

No, PRTG is proprietary network monitoring software by Paessler GmbH for which you need to own a commercial license if you want to monitor your business network. However, for small networks, PRTG offers a Freeware edition that comes with 100 sensors free of charge and includes important features like alerting, reporting, and network mapping.

Can PRTG only monitor bandwidth?

No, PRTG can monitor your entire IT infrastructure, including:

  • CPU and memory monitoring: It’s a good idea to monitor your hardware’s CPU usage, memory, and storage, since bottlenecks can creep up and cause devices to overload. With PRTG, you’ll be alerted before your devices crash so you can quickly see if their capacity limits have been exceeded.
  • Website monitoring: How stable is your website? Does it load quickly? Is it accessible by users all over the world? Do errors occur during the order process? PRTG comes with sensors that will answer these questions and more. If your website has a high volume of customer traffic, then monitoring is a must.
  • Cloud monitoring: You definitely need PRTG if you use worldwide cloud services, including email, virtual machines, and SaaS solutions. PRTG monitors the availability of each of these services.
  • QoS monitoring: Interrupted video calls? VoIP down yet again? Monitor your quality of service with PRTG to quickly identify loopholes and prevent emergencies before they occur.
  • File monitoring: Log files, event logs, file servers—PRTG monitors each and every file in your network. It even lets you monitor individual files, as well as folders and file contents.
  • And much more
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.

We asked: would you recommend PRTG? Over 95% of our customers say yes!

Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
