Network switches are used in Parallels H-Sphere to monitor the traffic load on dedicated servers and provide data to calculate bandwidth charges. They send traffic data to MRTG (The Multi Router Traffic Grapher) logical servers that display bandwidth graphs. The Round Robin Database Tool is used to store data on each network switch port in a separate RRD.
If you intend to lease your own dedicated servers to your clients, besides the ones that belong to your provider, and you want to monitor traffic on them, add your own network switches to the system.
Make sure switch is connected to network, prior to adding it via the interface. Parallels H-Sphere will operate with network interfaces (not physical network switches polled by MRTG servers) to collect statistics from all used ports: which ports are used by which particular dedicated servers.
To add a network switch:
On this page, you can edit your switches data (click Edit in the Controls column). Only unused switches can be deleted. Click numbers in the Ports In Use column to see dedicated servers connected to switches.
When you add dedicated server to the system, choose the network switch and its port assigned to the server. If you've done everything correctly, users of dedicated servers should be able to view traffic graphs from their control panels.
