I just installed NetMRG 0.18.2 and am starting to play around with configuring it. I went through the tutorials in the Wiki and have a single linux machine currently being monitored. This machine has multiple network interfaces that I want to monitor. So in the device tree under group->device I have the sub-devices eth0, eth1, and System all defined. The eth0 & eth1 ones were created automatically for me at some point, I forget exactly when. I added template graphs to monitor CPU, LAN traffic, load average, etc. When I click on the icon next to the server under the reporting device tree I see a bunch of graphs appear as I'd expect. Among the graphs are "hostname eth0" and "hostname eth1", but there's also a graph titled "hostname %ifDescr%". It's pretty obvious that this graph doesn't belong. Is there any way to get rid of it? I haven't been able to figure out a way to delete it...
Never mind. I figured it out. The "edit" link at the bottom of the graph page was so small I missed it the first few times I looked at the page...
