Network switches are used in 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.


Adding MRTG Logical Servers

Add MRTG service when installing H-Sphere 2.5 and higher. If you haven't done it with the installation or if you installed H-Sphere by updating from a version under H-Sphere 2.5 (which didn't have MRTG service yet), you need to add this service later. This procedure will result in installing the hsphere-mrtg-rrd system package on a target H-Sphere box, and MRTG logical server will appear in the H-Sphere interface (in the E. Manager -> L. Servers menu). If you plan that your resellers lease their own dedicated servers, besides the ones that belong to you, and that servers' traffic data is displayed properly to their end users, make sure to add a Service IP to this server.


Adding Network Switches

Make sure switch is connected to network, prior to adding it via the interface. 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:

  1. Go to Dedicated Servers -> Network switches
  2. On the Managing Network Switches page click Add new switch:
  3. Fill in the following data:
    • Device (IP or host name): network switch IP or host name.
    • Community Name: enter the community name which was physically assigned to it. If other than 'public', it's displayed as ****. You can see this info only when editing the switch data.
    • Switch Description: field for additional info.
    • Web URL: implemented to let you access the switch from the interface by clicking the URL icon on the Managing Nework Switches page.
    • Mrtg logical server: choose from available logical servers.
  4. Click Submit. The newly-added switch should appear on the Managing Nework Switches page:

    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.


Viewing MRTG Server Info

To view your MRTG logical server info, use E.Manager -> L. Servers menu. After you choose its name, a page similar to this appears:

Here you can see how many switches send data to this MRTG server, both the ones that belong to you and to your resellers.
