Hi All,

I am using the SNMP Traffic sensor pointed at the internet connection on our firewall. I'm getting results, but I would like to display them as a percentage of our maximum bandwidth.

i've seen this setting on other sensors, including netflow, but I can't find it on this sensor.

Am I missing it or is it simply not available on the SNMP Traffic sensor?

It's available, especially within this Sensor ;) This is to be configured in the actual channels settings of the Sensor, via the small gear in the channel(s). Select Display in percent of maximum and it will be displayed accordingly.

Nope, I don't see that setting. The channels don't have a gear icon at all.

Could you post a screenshot of that? All channels in Sensors have a small gear icon, i.e. channel settings :)

Stephan, in your reply it states that the sensor can be set to "Display in percent of maximum" It looks like this maximum is the maximum bandwidth use reported by the device and not the actual bandwidth of the interface being monitored.

It would make more sense for the SNMP Traffic sensor and the Netflow sensor to have a setting for actual bandwidth, and then display the percentage of that actual value.

Percent of maximum is not a very helpful setting for network monitoring.

For example, your competitor, IPSwitch WhatsUp Gold will learn the speed of the interface during the SNMP scan. This speed will be either the physical speed of the interface, or alternatively the speed set by the Bandwidth command on the router interface. There is also an option to manually set the speed of an interface in the WhatsUp Gold device setup.

If a router has an interface to an ISP, the rate of speed of the ISP Internet connection could be 10Mbps, but the physical speed of the interface from the router to the ISP interface box is often 1Gbps Ethernet hand-off. The WhatsUp Gold graph will show the SNMP traffic as a percentage of the 10Mbps.

That's a nice approach. The actual ifSpeed should be available for each interface (we can also update the Sensor name on it). We might to look into it :)
