Paessler Router Traffic Grapher (PRTG) is a network monitoring and bandwidth use software for Microsoft Windows by Paessler AG.
Overview
With PRTG bandwidth usage of a network can be monitored and classified using the three most common bandwidth data acquisition methods:
- SNMP: Reads traffic counters of network devices like switches, routers and servers
- Packet Sniffer: Looks at all data packets travelling through a network using the promiscuous mode and analyzes the network packets to find out the IP addresses, protocols, etc. of the source and target machine
- Netflow: Analyses Netflow protocol packets used mostly by Cisco routers
The usage data is constantly recorded and the historic data can be analyzed e.g. with data tables for usage billing and graphs for trend analysis via a web server interface and in a Windows GUI.
PRTG was originally developed by Dirk Paessler when he discovered how much effort it is to install and configure MRTG on Microsoft Windows systems. A freeware version is available.
