What is a network analyzer?

In IT, a network analyzer is a tool that records and analyzes the traffic on your network. A network analyzer breaks down traffic by different parameters and presents data flows in form of diagrams or tables. PRTG as a network analyzer helps you to break down traffic by connection, by protocol, and by IP address to identify the top talkers in your network. This facilitates the identification and solution of problems in your IT environment.




Network analysis with PRTG offers 4 advantages

Break down network traffic

Which applications monopolize your bandwidth? Which servers are regularly overloaded?  PRTG Network Monitor monitors all network devices and applications and presents a clear overview. SNMP, Packet Sniffing, Flow and WMI technologies are used by PRTG for analysis. With over 250 preconfigured sensors, your network elements can be quickly populated into PRTG.

Statistics and reports

PRTG collects all data on your network and visualizes it in tables, diagrams, and so-called toplists. For example, you can see changes in network performance over the last few months at a glance. The statistical information is a perfect basis for determining the need for an upgrade.

Moreover, PRTG contains a reporting system that automatically sends individual reports. This function is also ideal to inform colleagues outside IT about the network status.

Avoid bottlenecks


Bottlenecks reduce the performance on your entire network. Single applications could monopolize bandwidth just as overloaded WiFi networks or major online backups. With the network analysis of PRTG, you can quickly identify these bottlenecks and eliminate them in a focused manner.

Intelligent network updates

With PRTG, you always know about the capacities in your network. This helps you plan your IT infrastructure and enables you to update it in a focused and cost-efficient manner. Even savings in certain areas are possible with the help of PRTG.

PRTG offers long-term recording of your network data. This way, you can immediately identify unusual developments in your network and take proactive action, often eliminating errors even before they occur. Immediate notifications by e-mail, text message or push notifications in case user-defined or preset thresholds are exceeded allow fast intervention.
