Bandwidth Monitoring Sensors

The following sensors can be used for bandwidth monitoring:

• WMI Network Card: Measures traffic going through network cards (see WMI Sensors).
• SNMP Traffic: Supports monitoring bandwidth (bits/s) and volume (bytes), as well as the number of packets and errors via SNMP for a port or a network card on PCs, servers, switches, firewalls, printers (see SNMP Sensors).

• Packet Sniffer (Header): PRTG looks at the IPs and ports of source and destination to assess the protocol (see Packet Sniffer Sensors).
• Packet Sniffer (Content): PRTG captures the TCP packets, reassembles the data streams and then analyzes the content of the data using an internal set of rules to identify the type of traffic (see Packet Sniffer Sensors).

• NetFlow V5: Monitors Cisco switches using NetFlow V5 (see xFlow (NetFlow and sFlow) Sensors).
• NetFlow V9: Monitors Cisco switches using NetFlow V9 (see xFlow Sensors (NetFlow and sFlow)).
• sFlow: Monitors switches using sFlow (see xFlow Sensors (NetFlow and sFlow)).

To learn more about the four methods of bandwith monitoring in PRTG, see section Comparison of Bandwidth Monitoring Sensors.
