PRODUCT OVERVIEW

“PRTG helps us to keep control of our IT by making issues visible immediately – and everywhere. We always have an eye on the performance and availability of our IT and can react in time if any failures occur. On a long-term perspective, the monitoring data helps us with capacity planning so that we can deliver the required resources for our own systems as well as for our customers, without wasting money on unwarranted redundancies.”

Stein Erik Høybakk, Senior Network Engineer
TAFJORD

“All our production and business processes depend on SAP. But, of course, IT and production systems also play a crucial role in securing these processes. By incorporating SAP, production, and IT into one centralized monitoring system, we can quickly detect critical drops in performance and identify the causes of these issues. In fact, thanks to PRTG and itesys, this couldn’t be any easier.”

Andreas Schmidt, Senior Systems Engineer
Truma

internet traffic monitoring: FAQ

 

What is an internet traffic monitor?

An internet traffic monitor is a tool that tracks and analyzes data flowing through your network. It provides insights into bandwidth usage, network performance, and real-time traffic patterns. By monitoring network activity, admins can detect bottlenecks, optimize data flow, and troubleshoot issues with network devices like routers and firewalls.

How does Paessler PRTG monitor internet traffic?

Paessler PRTG monitors internet traffic using technologies like NetFlow, sFlow, and deep packet inspection. It collects data from routers, switches, and other network devices to visualize bandwidth usage, latency, and network activity. With customizable graphs and real-time alerts, PRTG helps admins identify network performance issues and optimize network connections.

Can PRTG help identify bandwidth hogs?

Yes, PRTG can identify bandwidth hogs by analyzing network traffic data in real time. It helps detect which endpoints or applications are consuming excessive bandwidth and allows you to optimize traffic flow and prevent slowdowns. PRTG provides detailed reports and notifications to ensure efficient use of network resources.

What types of traffic can PRTG monitor?

PRTG can monitor a wide range of traffic, including TCP/IP, VPN traffic, Wi-Fi connections, and traffic from various network devices like firewalls and switches. With its support for protocols such as NetFlow, SNMP, and sFlow, PRTG provides detailed network traffic analysis for both real-time and historical data.

Is Paessler PRTG compatible with Cisco routers?

Yes, Paessler PRTG is fully compatible with Cisco routers and other Cisco network devices. It can monitor traffic through Cisco devices using technologies like NetFlow and SNMP, providing real-time metrics on bandwidth usage, latency, and network performance. This makes PRTG an ideal solution for admins managing Cisco-powered infrastructures.

What is NetFlow?

NetFlow is a protocol developed by Cisco that collects and analyzes IP traffic as it enters or exits an interface. Paessler PRTG uses NetFlow to provide detailed insights into network traffic patterns, bandwidth usage, and network performance metrics. By monitoring NetFlow data, you can identify traffic trends, troubleshoot issues, and optimize bandwidth usage across your network.

What technologies are used for network traffic analysis?

Network traffic analysis relies on technologies such as NetFlow, sFlow, IPFIX, and deep packet inspection (DPI). Paessler PRTG supports these protocols to capture detailed data on traffic, bandwidth, and latency. By leveraging these technologies, PRTG helps you to monitor network activity, diagnose performance issues, and optimize bandwidth utilization across various endpoints, routers, and network connections.

What is a sensor in PRTG?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive. On average, you need about 5-10 sensors per device or one sensor per switch port.

We asked: would you recommend PRTG? Over 95% of our customers say yes!

Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
