Remote Access Traffic Statistics

We monitor traffic volume on selected Remote Access connections to the campus network.

For each monitored interface, you may view graphs showing the traffic volume in and out of that interface over several recent time periods (the past 31 hours, 8 days, 31 days, and 365 days). In most cases, volume is measured by bit rate and packet rate.

Traffic graphed as "incoming" (in GREEN) represents traffic entering the monitored network interface, while the traffic graphed as "outgoing" (in BLUE) represents traffic leaving the network interface.

We also monitor some devices for CPU load, free memory, or active modems.

The monitoring is performed with mrtg, rrdtool, and mrtg-rrd.

The display you see will be refreshed automatically by your Web browser every five minutes.
