PRTG Traffic Grapher 4.3 Supports Packet Sniffing and Cisco Netflow

FUERTH, Germany – July 20, 2005 - Paessler today announced the immediate availability of PRTG Traffic Grapher version 4.3, a Windows software solution that combines the most popular bandwidth monitoring requirements with new packet sniffing and Cisco Netflow capabilities.

PRTG Traffic Grapher monitors network and bandwidth usage, as well as other network parameters such as memory and CPU utilization. This information provides system administrators with live readings and periodical usage trends to optimize the efficiency, layout and setup of leased lines, routers, firewalls and servers as well as other network components.

Using the new packet sniffer, PRTG can inspect and account for all data packets travelling into, out of, and across a network. With the new Netflow support, the bandwidth usage on Cisco routers can be monitored right down to the finest details, even for high volume networks.

"PRTG helps customers maximize the utilisation of their network bandwidth," said Dirk Paessler, CEO of Paessler AG. "By adding a packet sniffer and Cisco router support, customers now have a complete set of data acquisition options to fully monitor their network’s usage."

American City Business Journals (ACBJ), one of the country’s largest publishers of metropolitan business newspapers, is one of the many companies to have successfully migrated to PRTG Traffic Grapher.

Bryan Hart, network administrator for ACBJ, said that after experiencing significant problems with another product, his company began using the PRTG network traffic monitor to monitor its remote-market routers and core network equipment at corporate headquarters. PRTG allows ACBJ to monitor all aspects of their network’s bandwidth activities. The team can now be more proactive than reactive. "It allows us to gather information that we simply didn’t have access to before," said Hart. "Without PRTG Traffic Grapher, we would have no history to help troubleshoot."

PRTG Traffic Grapher’s monitoring results may be viewed either via a Windows interface or Web pages delivered by the internal web server. Sample reports and screenshots may be found at

The software is available in both a Freeware edition (limited to monitoring only one network device and suitable for home users and SOHOs) and several different commercial editions, offering monitoring for multiple network devices and advanced features as required for larger businesses.

The fully functional freeware version of PRTG Traffic Grapher may be downloaded free of charge at: The upgrades to the commercial editions for multi-port and multi-device monitoring are available starting at US $49.95.
