WARNING: This documentation covers Parallels H-Sphere versions up to 3.1. For the latest up-to-date Parallels H-Sphere documentation, please proceed to the
official Parallels site.
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:
- Go to Dedicated Servers -> Network switches
- On the Managing Network Switches page click Add new switch:
- 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.
- 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
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.
