Ksysguard does not show eth3 in the graph.

[TommyB]

I posted a bug report on this issue, 357906 at https://bugs.kde.org/show_bug.cgi?id=357906
So far there has been no activity since I first reported it on January 12 and I am perplexed why no one is concerned that Ksysguard does not show eth3 on the graph.
Perhaps someone here can enlighten me as to why this bug is being ignored?
I am using Kubuntu 14.04 LTS at this time, while considering upgrading to 16.04 LTS.
Can anyone confirm that it is fixed in 16.04 or, ignored!
Thank you!

Being "unconfirmed", and no one else is reporting it, it is probably not a bug but a misconfiguration.
Your post lacks information:
computer make and model
type of network chip or card and the driver it is using
(use lshw to get this info)
Mine looks like this:

The description of Ethernet interface logical names is described here. And, assuming your Ethernet cat5 cable is not miswired or defective, you've got one card and two logical configurations, apparently without bridging.

The logical names are changeable, so you can configure eth3 to be eth0:

Ethernet Interface Logical Names

Interface logical names are configured in the file /etc/udev/rules.d/70-persistent-net.rules. If you would like control which interface receives a particular logical name, find the line matching the interfaces physical MAC address and modify the value of NAME=ethX to the desired logical name. Reboot the system to commit your changes.

Ksysmonitor is configurable. You can add a tab and configure it to report any logical name you wish.

Thank you!
You have no idea how many hours I have spent trying to find that information online.
At any rate it did work changing the logical name. Then, I ran a upload/download speed test and it registered nothing, flatline. The ethernet card is part of the motherboard, so that cannot be changed.
I guess I will have to put up without using ksysguard for checking the internet connection.
Thank you, again!

I don't run 16.04 but you might check the widgets and see if a network monitor is among them.

There are a couple of script utilities in the repository: ethstats and ethstatus. In the upper left hand corner of EVERY main window of any app in Linux is an icon. Left click on it and choose "More Actions". On that submenu is "Keep above others". You could resize the app so that just the info you want to watch is visible and move it to a corner or the top, and continue using other apps.
