What is bandwidth?

The term “bandwidth” is used to describe the maximum rate of data that can be transmitted in a network. It is measured in bits, kilobits (Kbit), megabits (Mbit), gigabits (Gbit), or terabits (Tbit) per second. Bandwidth problems can prevent data from “flowing.” Consequently, it is vital that IT managers test and monitor their bandwidth.

PRTG in practice: Test your bandwidth in 5 easy steps

 In order to test your maximum bandwidth, you’d have to put a maximum strain on your data line –
and therefore bring your entire network to a halt. For companies, this is not a viable option.  

Step 1:
Prepare your bandwidth test

Create three HTTP Advanced sensors to access files on servers operating at different speeds, such as one that houses a static website.

Step 2:
Perform your bandwidth test

Let the sensors run for a few hours at intervals of a few minutes each. The sensors will display the number of kilobits per second that were reached during the download.

Step 3:
Evaluate your data rate (KB/s)

For example, if you have a data line with a specified bandwidth of 4 Mbit/s, it should take 1,000 ms (1 second) to download a 500 KB file. 4 Mbit/s = 0.5 MB/s = 500 KB/s.

Step 4:
End your bandwidth test

If they run for too long, bandwidth tests can generate enormous amounts of data. You should therefore end the test quickly and disable the sensors. 

Step 5:
Expand your test to monitoring

This kind of test only checks your bandwidth at a specific moment in time. It does not, however, reveal the sources of the problems which may be affecting your bandwidth. In large networks, these may include a router or a switch. With PRTG, you can monitor your entire network.

 

 

Bandwidth at a glance – A case study

PRTG is used by more than 300,000 administrators worldwide – and nearly all of them use it to monitor their traffic and bandwidth. Take Aquafin, for example, where employees check the data transfer rate themselves and therefore rely much less on the IT department. “We wanted a scalable network monitoring tool,” explains the company’s IT manager.

So you tested your bandwidth...now what?
The advantages of
a professional monitoring tool

Take prompt action

PRTG comes with a built-in alarm that automatically notifies IT managers in the event of a bandwidth disruption or a malfunction affecting an important component in the network. As a result, you can quickly spring into action – usually before your coworkers even notice that something is wrong. What’s more, the alarm is entirely customizable, allowing you to define exactly how and when you wish to be notified.

Identify errors faster

File transfers, backups, slow applications...in both the LAN and the WLAN: there are many reasons why your bandwidth and data traffic may be disrupted. With PRTG, you’ll immediately see where the problem lies and can quickly get down to troubleshooting.

Work with more peace of mind

A quick glance at the customizable dashboard in PRTG is all it takes to make sure everything is running smoothly in the network. The dashboard displays the status of servers, routers, switches, firewalls, and much more. If something goes wrong, you’ll be notified at once. You can therefore work with total peace of mind and concentrate on other important IT issues.

Keep your system tidy

PRTG is compatible with all the biggest manufacturers, including Cisco, Dell, Juniper, and many more. Centralized monitoring software, it lets you do away with a mishmash of monitoring tools. 

Easy to get started

PRTG comes with 250 preconfigured sensors that are automatically created while installing the software. You can also configure its sensors to meet your own specific needs. 100 sensors are free of charge for as long as you like. If you need more, simply choose an appropriate license.

 

 

“The greatest advantage of PRTG? You get to rest easy.“

Steffen Ille, Bauhaus-University of Weimar, Germany

 

3 types of sensors that every
sysadmin needs

SNMP sensors

Our SNMP sensors are perfect for monitoring hardware such as servers, computers, routers, and switches. Preconfigured SNMP sensors are available for manufacturers such as Cisco, Dell, and HP. Learn more about SNMP monitoring and SNMP message types.

IP SLA sensors

Our software monitors the quality of service of your network in real time. Quality of service is vital, especially when it comes to video conferences and VoIP. PRTG comes with special sensors such as the Cisco IP SLA Sensor to monitor the quality of service in your network. More on IP SLA monitoring.

Traffic sensors

Our flow sensors and Packet Sniffer Sensor provide for in-depth monitoring of your traffic. Among other things, you’ll discover which connections and applications are consuming the most bandwidth. More on packet sniffing and flow monitoring

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.

Everyday bandwidth tests

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
