Paessler PRTG Traffic Grapher
(2 votes, average: 9 out of 10)
Loading ...Traffic Grapher monitors network traffic and classifies it by IP address, protocol and other parameters. It acquires traffic information through SNMP, LAN and WLAN packet sniffing and Cisco’s NetFlow. It can also monitor latency by measuring PING times. Graphs show live data (for the past five minutes to an hour), averages for up to 48 hours, hourly averages for up to 60, daily average for up to a year, and more. An internal database can export results as CSV files and zip and purge old data. Reports are available in HTML, PDF, Excel and other formats. An internal Web server offers public or authenticated access to the monitoring results.
