I googled, and couldn't find anything regarding this, but I'm not seeing any interface graphs for hosts with CentOS7 / RedHat 7, and I'm trying to understand why. RPMs freshly built from 4.3.18 for CentOS7, the client is running 4.3.18, and the server is 4.3.9. Is there some sort of incompatability here with the output from ifconfig or ifstat?
The client data parser looks for interface counters in the [ifstat] section of the client data message. I don't have a RHEL7/CentOS7 system to compare, but it could be that the format of "ifstat" is different.
First, see if your client messages contain an [ifstat] section. You can get to your client message by viewing the "conn" status page for the server and then clicking on "Client data" link.
The layout has changed a little bit, but it's still parse-able by the default tools.
A bigger issue is that in the fancy new late-Fedora/EL7 world, "ifconfig" is deprecated (actually, it's apparently been deprecated for like a decade in favor of 'ip', but I don't know anyone who doesn't use it) thanks to the move away from SysV initscripts and is no longer installed by default.
Ensure that the "net-tools" RPM is installed if it isn't already; if you have a blank ifstat section, this is most likely the case.
