What is Bandwidth Monitoring?
Bandwidth monitoring tools display real-time data such as download and upload speeds and help prevent network strain.
Private individuals and professionals alike use bandwidth monitoring to check for available bandwidth.
Find out who is hogging your bandwidth
"Who is hogging my bandwidth?" - maybe you hear that frustrating question over and over again from your users. They are complaining about a slow network and you need to identify the root of the problem.
PRTG Network Monitor helps you determine how much bandwidth your devices and applications are using. Depending on your network and hardware, you can use different protocols like SNMP, flow or packet sniffing.
How to check bandwidth usage
Most bandwidth analysis solutions are only able to check internet traffic on a single device. For measuring all the traffic in your network, you need to monitor the data directly on your routers. Protocols like SNMP, NetFlow or WMI allow you to monitor bandwidth usage of your entire network. By using the Network Bandwidth Analyzer PRTG you get informed about all ingoing and outgoing traffic and see what application or what servers are using up the most bandwidth.
PRTG makes bandwidth monitoring easy
With PRTG Network Monitor, it is easy to track and check bandwidth usage in your network. The bandwidth tool reads the traffic data from your router and displays the results in three graphs. This way, you will quickly and easily be able to check bandwidth usage and the amount of data transferred.
Bandwidth monitoring for professionals and consumers alike
iBandwidth 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. Read more ...
Private users: Many private users are interested in determining the amount of bandwidth they have at their disposal. Or more precisely: if the bandwidth guaranteed by their internet service provider is indeed the amount that is available. In this context, many consumers investigate speed tests, DSL bandwidth, or whether their cell phones or tablets are able to access the respective bandwidth.
- In addition to PRTG, which of course can help in this area, you may opt for a simple cable speed test which can be found online on a variety of different sites and often times also measures the ping. Start using our bandwidth manager for your network.
Professional settings: In professional settings (businesses or large organizations), reduced bandwidth has significantly graver consequences. Disruptions lead to idleness on the part of employees and customers and a corresponding loss of sales. Administrators must promptly expose and eliminate bandwidth hogs.
- In this instance, our PRTG bandwidth monitoring tool will help you to monitor bandwidth, detect and measure heavy bandwidth overloads, quickly recognize potential disruptions - and get down to the root of the problem.
3 situations where PRTG comes in handy
Your co-workers complain that the programs used internally are too slow? Your customers are unhappy because your website constantly seems bogged down? Then the problem probably lies with your bandwidth.
Malfunctions when backing up
No IT can do without backups. In general, backups or database synchronizations require a great deal of bandwidth. Without the proper amount of bandwidth your network can be brought to its knees.
Problems with large file transfers
Practically every company sends large files. These files consume a correspondingly high amount of bandwidth. But bottlenecks lurking in every network slow down transfers.
With PRTG, you'll be able to promptly identify potential bandwidth overloads and quickly pinpoint the causes of crashes. One single network component overloading can swiftly result in a significant loss of bandwidth.
Obtain a comprehensive overview of your bandwidth usage
PRTG Network Monitor reads the complete traffic data from your router and provides detailed statistics about which services and programs use your bandwidth, and where potential bottlenecks could be.
PRTG displays your bandwidth usage in graphs and toplists and shows net bandwidth consumption based on various parameters such as port numbers, IP addresses, protocols, etc., using either Packet Sniffing or xFlow sensors (NetFlow, sFlow, jFlow, and IPFIX).
iWhat is a sensor?
In PRTG, “Sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.
Custom alerts notify you about bandwidth shortages via SMS, email, or push notifications. This ensures you can react proactively to all bandwidth issues and troubleshoot problems before they become severe.
Monitoring bandwidth usage is key to better network management.
“We can all work with greater peace of mind knowing that our systems are constantly being monitored.”

Test bandwidth: use PRTG to test with success!
You’d like to know if your ISP actually provides the bandwidth they’ve promised? Then just like many administrators, you probably perform frequent SLA checks. But how do you test bandwidth? Two challenges arise:
Challenge 1: In order to test the maximum throughput of your bandwidth, you must use your line to maximum capacity. This means there will be no more resources for other data during the network test. In other words, you'll paralyze your network.
Challenge 2: For a 100% measurement, you’ll essentially need two computers which are directly located on the ends of the line whose bandwidth you would like to test. Otherwise you will also simultaneously test all network devices found on the “test track.”
For these reasons, you cannot measure the bandwidth directly over the course of the entire test, but must test the speed of the line by generating short load peaks, e.g. by downloading a small file (a few kB) every few minutes and measuring the time it takes for the download.
The solution: This is how to test your bandwidth with PRTG:
- Create three HTTP Advanced sensors, which access several files of circa 500 kB from a variety of "fast servers" (e.g. your ISP's static websites).
- Let the sensors run for a few hours with a 5-minute interval. The sensors have a channel which specify the bandwidths achieved during the file download in Kbps.
- If, for example, you have a data line with a specified bandwidth of 4 Mbps, the network test of a 500 kB file should last 1,000 ms (1 second): 4 Megabits per second = .5 MB per second = 500 kB per second.
If your line is used by others during the network test, you will see jitter (unwanted fluctuations) on the curve, for your test did not always run with the full amount of available bandwidth. If there was no other traffic on the line, your curve should closely resemble a straight line. Bandwidth checks with PRTG will allow you to monitor your network and potential bottlenecks.
Attention! If you download a 500 kB file every 60 seconds, you'll generate a data volume of 720 MB per day!

Practical tip: “Hey Mathias, what would you tell administrators who wish to monitor their bandwidth?”
“Instead of trying to measure bandwidth by way of an extra, simulated load, you should have a look around for actions which do that anyway – and then monitor them. For example, when you perform backups, you often put great strain on the bandwidth and can thus easily recognize shortages or bottlenecks.”
Mathias Hengl, PRTG Developer at PAESSLER AG
