Interface Traffic Indicator is a graph utility to measure incoming and outgoing traffic on an interface in bits/sec, bytes/sec or utilization. Works on all SNMP-capable devices (computers, NICs, switches, routers, etc.) with adjustable poll intervall down to three seconds. You can use this software in a professional network environment to monitor selected network interfaces (even backplane ports if the device provides the information) or you can monitor your home network or cable/modem/ISDN connection to the internet.
Interface Traffic Indicator enables you to measure incoming and outgoing traffic for SNMP-capable (MIB-2) interfaces, including compatible network cards, switches, routers, and other devices. You can customize the polling interval from 1-120 seconds, and optionally write a log file. The current traffic is displayed in a bytes or bit/sec graph display.
