How jFlow monitoring with PRTG works
During bandwidth monitoring via the jFlow protocol, the router or switch collects data packets and groups them to flows. This information about the flows is sent to PRTG via UDP.
You can sort the flow automatically by traffic type (mail, FTP, or WWW) and use it for statistical processing and visualization. This allows you to immediately see which applications and devices use your bandwidth within your network.
You can also minimize your bandwidth and CPU usage by turning on sampling (if your router supports it) so only every n-th data packet is sent to PRTG.
You detect the originators of the data traffic within your network sorted by sender/target IP, sender/target port, IP protocol, and service type.
The visual presentation of the monitoring data in so-called toplists provides additional optimal analysis conditions. PRTG will immediately alert you to sudden increases of bandwidth usage of a certain network address or application.
