Display the network traffic?

Hi there,

first I'm new in Opsview and also Linux, so I don't have that much experience in this topic.

My current task is to set up the network monitoring in our company ( it's not that big...under 100 devices). We have a Pro Licence and Opsview pro installed on a server but for test purpose I'm using the opsview core version as an VM downloaded from here.
The first steps were pretty easy so I've set up things like monitoring the status of a device and send notifications via email.
My next step is to track the total traffic in our company. For testing I have a switch with SNMP activated...but now I have no idea what to do next. I can see how many interfaces are up/down but how can I see the total traffic on the switch? I tried it with the module "MRTG" but I can't see anything here and I can't find any documentation.


Edit: Ok, i just noticed that I forgot to check "Use MRTG for Interfaces". But it still won't work since I get the message "No such host"...any idea?

Do the following:

1. Add the network device as a host (Settings > Hosts > + )

2. Populate the first page with the address of the switch, etc and add the host template 'SNMP - MIB II' at the bottom, then click submit.

3. Go to the SMMP tab, enter your community string and click 'Test connection' to make sure it passes.

4. When it is passing, click 'Submit and edit host interfaces'.

5. In this page, click 'query host', this will bring up all the interfaces on that device (i.e. ports). Here you can choose which ones you want to monitor, what the thresholds are, etc.

6. Once you've selected all these, click submit. Then, reload (Settings > Apply changes / Reload).

7. Once your system is back, you can navigate to Monitoring > Hosts > YOUR_NETWORK_DEVICE and you will see a traffic-per-interface metric. Give it 5 minutes and then reload again (as per step 6), as this will force Opsview to recognise the new graphable data.

8. Now you have graphable data, go to dashboard and create some sweet performance graphs.

Hope this helps!
