Keep your data usage under control with PRTG 

Measuring, analyzing, and monitoring the usage of data is part of standard monitoring tools. However, all of the advantages that are associated with comprehensive data usage monitoring cannot be exploited when using such monitoring tools. This is because certain things can possibly be done incorrectly or, alternatively, with the help of a sophisticated monitoring solution.

The ideal data usage monitoring for you should:

  • continuously monitor internet usage
  • always keep an eye on bandwidth
  • monitor routers and switches
  • use SNMP, WMI, packet sniffing, or xFlow
  • save you a lot of time, nerves, and money



3 considerations to always keep your data usage under control


Observe bandwidth

Particularly in expanding companies, bandwidth is gradually used to a greater extent. With reliable SNMP sensors, you get an overview of the used bandwidth. With xFlow and packet sniffing sensors, you can see which devices and applications are using your bandwidth and to what extent. With a good monitoring solution, you can perform long-term analyses and generate reports with a single click.

Customizing sensors

Make sure you have internet access

Often, problems occur because individual routers or switches fail. The reason for this can be missing updates or material damage. With certain sensor types, you can monitor hardware elements such as CPU, memory usage, and hard disks from many manufacturers.

Network performance analysis

Eliminate bottlenecks

While looking at typical data usage, you will discover bottlenecks in every network. They mostly occur temporarily or locally. With a good monitoring solution, you can monitor your network 24 hours a day, 7 days a week. This allows you to detect when bottlenecks in internet usage occur, for example, during backups or when using certain applications. This is how you make your network fit.


Wait, what?

Bandwidth is measured as the amount of data that can be transferred from one point to another within a network in a given period of time. Typically, bandwidth is expressed as bit rate and measured in bits per second (bps). It refers to the transmission capacity of a connection and is an important factor in determining the quality and speed of a network. Learn more about bandwidth on this IT Explained page.

Data usage: What makes for good monitoring?

We believe that PRTG is the best solution for reliable data usage monitoring as well as for many other applications.
It has been in the market for over 20 years and it is based on the feedback of 300,000 users.


Fast root cause

Looking for the root cause of slow applications or other problems can be very tedious and costly if you do not have a monitoring tool. PRTG offers you comprehensive monitoring. For monitoring your bandwidth alone, you can choose from around 20 sensors that can be set up automatically. These range from the IPFIX sensor, to the sFlow sensor, and on to the Windows Network Card sensor.

Detect capacity utilization at an early stage

Bandwidth cannot be monitored extensively enough. With PRTG, you are able to detect early when a full utilization of your bandwidth is reached. And you are able to monitor the whole way up to full utilization as well. This way, you can plan new resources in time and your company can grow without having to worry about capacity issues.

Detect bottlenecks

With PRTG, you can monitor bandwidth over a longer period of time and also identify when bandwidth is being used to its fullest. This allows you to plan early on to increase bandwidth at certain times, for example, when your website is under a heavy amount of load, when users are heavily accessing applications, or in other data usage scenarios.

Reduce costs

By detecting and fixing bandwidth hogs, you increase the efficiency of your network. With our bandwidth calculator, you will permanently save costs. These measures alone usually pay for the purchase of PRTG within a short time.

Increase satisfaction

With PRTG, you ensure stable bandwidth, you increase the reliability of your network, and you simply have better control of your IT infrastructure. This is an important part of making your employees work more efficiently and of making your customers more satisfied.

How to set up bandwidth monitoring in PRTG in 4 steps

Let's get concrete and have a look at the data usage monitoring topic to see what questions you need to ask yourself so that you can implement bandwidth monitoring as efficiently as possible:

  1. What's the difference between WMI, SNMP, xFlow, and packet sniffer-based monitoring?
  2. What are the prerequisites for bandwidth monitoring?
  3. How to set up bandwidth monitoring in 4 steps?
  4. How to visualize your bandwidth monitoring data?
  5. Why should you create a report about your bandwidth monitoring?

The detailed answers to these questions can be found on this how-to page on bandwidth monitoring.


Hey Mathias, what advice would you give an administrator who wants to monitor his bandwidth?

“Instead of additionally trying to measure bandwidth via artificial load, you should look for actions that do it anyway – and then monitor those. For example, when you're doing backups, you often have heavy bandwidth usage and can easily spot bottlenecks.”

Mathias Hengl, PRTG developer at Paessler AG
