Checking Traffic Usage

We are monitoring traffic usage with a tool called cacti, which is running on and is available via the web at

It works by polling both our Telehouse and XO switches via SNMP. It measures traffic for the entire physical server (all virtual servers combined). cacti is configured with each server name mapped to a particular port on the switch.

Login information is stored in keyring (only available to administrators).

If you want to determine which virtual server on a given physical server is taking up bandwidth, the easiest way is to (install and) run iftop.
