Simple Network Management Protocol (SNMP) is a networking protocol used for the management and monitoring of network-connected devices in Internet Protocol networks. The SNMP protocol is embedded in multiple local devices such as routers, switches, servers, firewalls, and wireless access points accessible using their IP address. PRTG enables you to monitor your network's total bandwidth usage, measure network throughput, monitor internet usage by IP address, and to identify and troubleshoot bandwidth delay. Using packet sniffing and NetFlow / sFlow / jFlow, you can create toplists which show you which computers or applications are responsible for most of the bandwidth.
