How does PRTG Traffic Grapher work?
For network usage and bandwidth monitoring PRTG Traffic Grapher supports three methods to acquire the data: • It can log the amount of data flowing in and out of SNMP enabled network components using the “Internet MIB-2” standard • It can inspect all data packets passing a computer’s network card (“packet sniffing”) • It can use bandwidth usage data sent by Cisco routers using the Netflow protocol (V5)
