PRTG monitors your company’s
network usage in real time

  • PRTG monitors devices, applications, and bandwidth
  • PRTG sounds the alarm when network loads get too high
  • PRTG comes with a dashboard so you can quickly check the status of your network



Network usage: Less is better?
Two case scenarios

Increasing network usage

A medium-sized company has a great deal of bandwidth. Nevertheless, its download speeds are slow. Its network load is too low, and its available bandwidth is not being put to optimal use. The sysadmin hopes to find the bottleneck. He uses PRTG SNMP sensors to monitor the hardware in his firm. The result: he discovers an old switch that is malfunctioning because of several missed updates. After the updates, network usage rises considerably.

Reducing network usage

The network in a large organization has been at full capacity for several months. Overloads are now everyday occurrences. The network is distributed across several locations throughout the city. The IT team goes about finding ways to reduce the network load. They use the PRTG Packet Sniffer Sensor and Flow sensors to determine the amount of bandwidth being used by the network’s devices and applications. Their conclusion: new software in one of the firm’s departments was configured incorrectly and causing the overload. 

 

Sensors for measuring network activity

Measuring bandwidth

Measuring bandwidth

The SNMP Traffic Sensor lets you see the speed at which data is flowing through your network. This includes both incoming and outgoing traffic. Your dashboard provides you with a constant overview of the amount of bandwidth being consumed. In the event of problems, PRTG notifies you at once.

Protocols, data types, IP addresses

Protocols, data types, IP addresses

You can use the Packet Sniffer Sensor and NetFlow sensors to filter your data traffic. As a result, you'll get an in-depth look at the load values of your network. Protocols, data types, and IP addresses are displayed on easy-to-read dashboards. You therefore get a clear overview of your network’s top talkers, as well as other important values. PRTG also comes with sensors for Flow technologies such as 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.

Three good reasons to go with PRTG

PRTG lets you leave your work at the office

PRTG lets you leave your work at the office

With PRTG running in the background, you can sit back and relax knowing all is OK. Otherwise the PRTG alarm - which you configured yourself - would have already notified you that something is wrong. Go home relaxed, enjoy the weekend, and unplug completely while on vacation. PRTG gives you real peace of mind. And that’s priceless.

PRTG allows for swift troubleshooting

Thanks to the PRTG dashboard, you can immediately recognize even the smallest of problems. You’ll be like an eagle who sees a mouse from hundreds of feet away – and already on the floor tightening the screws on the server before your coworkers have a chance to put down their coffee and call the support line.

With PRTG, your network stays fit as a fiddle

With PRTG, your network stays fit as a fiddle

Everything ages – including your network. But unfortunately, your network doesn’t always look its age. Luckily, you have PRTG. PRTG lets you run long-term analyses. It will show you which routers and switches are ailing and in need of rejuvenation. Your network thus stays fit and trim well into the future – and you can save yourself some wrinkles.

A sneak peek into network usage monitoring with PRTG

Network utilization tools: An overview

Free Windows monitoring tools

Free Windows monitoring tools

Open source software (such as Nagios) is easy to find. At first glance, these free tools appear to be cost-effective. But that’s not taking into account the extra time required for their configuration. Post-installation modifications are also extremely time-consuming. We’ve put Nagios to the test. See our comparison of Nagios vs. PRTG. Windows itself also comes with free monitoring tools. But these tools are rather limited in scope. They will allow you as a sysadmin to check individual aspects of your network, but are unable to provide easy-to-understand monitoring data for the other employees in your company.

Professional tools like PRTG

Professional tools like PRTG

Hardware, software, applications: PRTG monitors each and every part of your network. PRTG is a professional tool used by more than 200,000 administrators worldwide. No wonder: PRTG takes just minutes to set up. The alarm feature is included, and our technical support department provides quick answers to nearly every question you might have. This of course comes with a price – one that is easy to justify when you consider all the time you will save.

Dealing with network load problems?
Monitoring vs. analysis

Network load monitoring

PRTG is a network monitoring tool that provides you with a quick overview. It therefore enables you to promptly and conveniently eliminate potential sources of error – e.g. by analyzing individual data packets. Thanks to PRTG toplists, you can spot top talkers and top connections. You cannot, however, analyze the content of individual files.

Analysis of individual files

Tools such as Wireshark and other software allow you to perform detailed and extensive network analyses. In the event of more serious network usage problems, you’ll probably need a combination of several tools to get to the root of the problem. Read how PRTG can help with network analyses, and where its limits lie.

 

Backups – a common source of network problems


Backup

 

Network problems seem to always crop up during backups. PRTG helps you determine the network load during backups, and identify the causes of any problems which may arise. Example: Many companies and organizations use a variety of different backup tools. But when all these tools are launched at the same time, the network tends to overload.

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 AG

Three tips for optimizing network performance

Regularly eliminate bottlenecks

Regularly eliminate bottlenecks

Bottlenecks are present in all large networks. Most of the time, the IT department even knows that they are there. But usually there is not enough time in the workday to go about eliminating them. That’s where PRTG comes in. Its built-in alarm system immediately notifies you in the event of a bottleneck, thus allowing you to quickly proceed with its elimination. The time you save can be used for fixing other bugs and problems. 

Load up on bandwidth

Load up on bandwidth

The most effective method for optimizing network performance is to increase your bandwidth. This of course costs money, but also results in considerably fewer crashes. During downtime, employees are unproductive. Customer inquiries cannot be answered, and the company risks losses in sales. Don’t underestimate the cost of downtime. We at Paessler have increased the capacities of our data lines to ensure our processes are always up and running.

Get rid of outdated hardware

Get rid of outdated hardware

Network problems may also be caused by outdated hardware. This hardware not only includes old routers and switches, but also poorly performing servers. PRTG lets you identify these obstacles. Its built-in reporting function generates easy-to-read charts and graphs which also allow department heads to ascertain where improvements must be made. PRTG therefore helps you to optimize the performance of your network.

Quality of service

Does your network suffer from packet loss? Your coworkers complain because the VoIP is down and their video calls keep failing? PRTG is the perfect tool for monitoring quality of service. It keeps a constant eye on jitter, latency, and your MOS.

Windows performance counters

There are a number of different possibilities for monitoring Window systems. The most common one is Windows Management Instrumentation (WMI). Compared to other technologies, however, WMI requires a great deal of the network’s load. Windows performance counters can be used as an alternative to WMI. Find out more about Windows performance counters.

CDN monitoring

The websites of international companies are accessed by users from all over the world – not just customers but also suppliers and employees. Many IT teams set up content delivery networks (CDNs) to ensure their network performance does not drop. PRTG lets you monitor these CDNs. Learn more about CDN monitoring.
