• PRTG Network Monitor is an agentless network monitoring software.
  • This network monitor tool consists of two main system parts: Core server and Probe.


These days, one of the most important aspects of cyber security is network monitoring. We have already published a detailed post on the importance and how to monitor the network. We suggest you read it. And but PRTG Network Monitor (Paessler Router Traffic Grapher) is an agentless network monitoring software from Paessler AG. It can monitor and classify system conditions like bandwidth usage or uptime and collect statistics from miscellaneous hosts as switches, routers, servers and other devices and applications.

We can say that PRTG is a great network monitoring tool for professionals. Why do we make such a claim? Because:

  • This software automatically discovers entire network. PRTG scans predefined areas of an enterprise network and then creates a device list from this data.
  • You be able create Groups within the Windows (or Browser-based) Desktop. Within those Groups you can create Devices and Sensors (Ping, HTTP, FTP, NTP, SIP, SMTP, SNMP and Switch Traffic)
  • This software is based on sensors that are configured for a specific purpose. PRTG Network Monitor has over 200 different predefined sensors For example, there are HTTP, FTP application sensors and hardware-specific sensors for switches, routers and servers. These sensors retrieve statistics from the monitored instances (like processor, memory, database information, temperature)
  • This software has free network monitoring software with 100 sensors.
  • Another advantage of this software is that it is very simple and fast to install.
  • This software alerts to network administrators about uptimes and downtimes or slow servers.
  • In this network monitor tool, the database system stores raw monitoring results as well as logs, Toplists, and tickets. This outperforms Structured Query Language (SQL) servers for monitoring data. Even you can also access the database through the PRTG.
  • System health monitoring of various hardware devices
  • This software has a SSL-secured web server with HTTP and HTTPS support for the web interface
  • Service level agreement (SLA) monitoring
  • Graphics engine for user-friendly live graphs and historic data graphs
  • Network device monitoring and bandwidth accounting and also application monitoring
  • This software has an email relay server for automatic email delivery
  • Data publishing with real-time dashboards (private and public maps) including live performance and status information
  • Classifying network traffic by source or destination, as well as content
  • And a lot of other features

This network monitor tool consists of two main system parts:

  • Core server: For using on premises
  • Probe: For using hosted by Paessler
