Why choose PRTG for bandwidth monitoring?

Troubleshoot "bandwidth hogs" faster

Paessler PRTG helps you troubleshoot bandwidth issues faster with a comprehensive network bandwidth monitor. You can choose from around 20 preconfigured sensors for bandwidth monitoring that are set up with just a few clicks. This way, you can more quickly find out which devices or applications are hogging your bandwidth.

Measure all traffic in your network

Most bandwidth analysis solutions only check traffic on a single device. The bandwidth monitoring software PRTG measures all network traffic by monitoring data directly on your routers using protocols like SNMP, WMI, flow (NetFlow, jFlow, sFlow, IPFIX), or packet sniffing. Monitor all ingoing and outgoing traffic and see which applications or servers are using the most bandwidth.

Monitor over a longer period

PRTG lets you keep an eye on your bandwidth over a longer period of time and recognizes when utilization spikes. This helps you plan for more bandwidth at key times, like when your website is in high demand, when users draw heavily upon applications, or when an update is pending.

Diagnose capacity & plan more efficiently

When your bandwidth is slowly reaching its limit, PRTG bandwidth monitor notifies you even before maximum capacity has been reached. This lets you plan for new resources in a timely manner, ensures a high QoS and helps prevent performance issues.

Reduce costs & improve satisfaction

By removing bandwidth hogs, you'll increase the efficiency of your network. These savings quickly compensate for the cost of PRTG. You'll also boost the reliability of your network and enjoy greater control of your IT infrastructure. This way, you'll improve employee performance and boost customer satisfaction.

What is bandwidth monitoring?

Bandwidth monitoring is a method to measure the actual bandwidth that is available on a local system (LAN or WiFi). Bandwidth monitoring tools display real-time data such as download and upload speed, or latency and thus help prevent network strain and aid in troubleshooting.

Private individuals and professionals alike use bandwidth monitoring with PRTG to check for available bandwidth.

 

What bandwidth monitoring looks like in PRTG

 

With PRTG, it is easy to track and check bandwidth usage in your network. The bandwidth tool reads the traffic data directly from your routers and visualizes the results, for example, in so-called toplist graphs. This way, you will quickly and easily be able to check bandwidth usage and the amount of data transferred.

 i How PRTG defines sensors

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.

Get a comprehensive overview of your bandwidth usage with PRTG

Monitoring bandwidth usage is key to better network management

 

Find the source of bottlenecks

PRTG reads the complete traffic data directly from your routers and provides detailed statistics about which services and applications use your bandwidth and where potential bottlenecks could be.

  • Monitor users
  • Monitor devices
  • Monitor services

Monitor bandwidth by any parameter

PRTG displays your bandwidth usage in graphs and toplists and shows net bandwidth consumption based on various parameters using, for example, packet sniffing or flow sensors (NetFlow, sFlow, jFlow, or IPFIX).

Configure custom alerts & notifications

Customizable alerts notify you about bandwidth shortages. This ensures that you can react proactively to all bandwidth issues and troubleshoot problems before they become critical.

  • SMS alerts
  • Push notifications
  • Email alerts (and more)
 

 

 

 

 

 

 

 

 

 

Bandwidth monitoring for professionals

 

In professional business settings, it has severe consequences if only limited bandwidth is available. Disruptions lead to idleness on the part of employees and customers – and a corresponding loss of sales and revenue. This is why administrators must be able to immediately determine and eliminate bandwidth hogs.

PRTG solves bandwidth issues by helping you to...

  • Easily detect & measure heavy bandwidth overloads
  • Quickly recognize potential disruptions
  • Clearly see which user, service, or device is using the most bandwidth

3 use cases for PRTG bandwidth monitoring

One single network component that overloads can bring your network to its knees. PRTG quickly identifies potential bandwidth bottlenecks and pinpoints the root causes of crashes in likely scenarios.

 

Problems with large file transfers

Every company sends large files, which consumes a lot of bandwidth. PRTG helps you avoid the bottlenecks lurking in your network that slow down or disrupt large file transfers and cost you dearly in time and money.

Slow applications and services

Your coworkers complain that internal programs are running slowly. Your customers complain that your website seems bogged down. PRTG solves this by showing you the cause of overloads and keeping your network at maximum efficiency.

Backup malfunctions and disruptions

No IT can do without backups. But database synchronizations and backups require a lot of bandwidth – one overload or bottleneck can disrupt everything. PRTG alerts you of bandwidth shortages so you can prevent overloads before they occur.

Case study: Austria's rail traffic relies on PRTG

 

oebb-logo.png

Due to business-critical applications, it is of the utmost importance that the ÖBB Infrastruktur AG data network runs flawlessly at all times. To make this a reality, the management installed PRTG Network Monitor. PRTG is used for monitoring the bandwidth of central routers and switches in the network so administrators can determine the most important key parameters for utilization and availability. In total, monitoring the ÖBB data network consists of several thousand PRTG sensors that query relevant metrics at regular intervals.

The challenge: How to test bandwidth

Would you like to know if your Internet service provider actually provides the bandwidth they've promised? Like many administrators, you probably perform many SLA checks – but how do you test your bandwidth?

 

Two primary challenges of testing bandwidth

 

1. Paralyzing your network

To test the maximum throughput, you must use your line to maximum capacity. This means that there will be no more resources for other data during the network test. In other words, you'll paralyze your network.

 

2. Isolating the test track

For a 100% measurement, you'll essentially need two computers which are directly located on the ends of the line whose bandwidth you want to test. Otherwise, you will simultaneously test all network devices found on the "test track".

Test connection speed

For these reasons, you cannot measure the bandwidth directly during the entire test, but must test the speed of the connection by generating short load peaks. You can do this, for example, by downloading a small file (a few KB) every few minutes and measuring the time it takes for the download to finish.

 

The solution: PRTG makes it easier to test bandwidth

 

 flexible

Create three HTTP Advanced sensors that access several files of about 500 KB each from various "fast servers" (for example, the static websites of your Internet service provider).

 flexible

Let the sensors run for a few hours with a 5-minute scanning interval. The sensors have a channel that specifies the bandwidth achieved during the file download in Kbps.

 flexible

If you have a data line with a specified bandwidth of 4 Mbps, for example, the network test of downloading a 500 KB file should last 1 second: 4 Megabits per second = 0.5 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 because your test did not always run with the full amount of available bandwidth. If during the test 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 closely and detect potential bottlenecks before they can cause real harm.

   Attention!

If you download a 500 KB file every 60 seconds, you'll generate a data volume of
720 MB per day!

mathias hengl

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
