Believe the Graphviz Graph Visualization Software is a prerequisite for the network map to work. You can download it from www.graphviz.org

First, when I try to display the Local Network Traffic Graph, I get an error (see below). I ensured that graphviz is installed and when I run the command listed below from the command line as root, I get the same error. Local Network Traffic Map ERROR Creation of network map failed Command was: /usr/bin/dot -Tpng -Goverlap=false /var/ntop/ntop.dot -o /var/ntop/network_map.png 2>&1 Results were: Error: Layout was not done. Missing layout plugins? Second, when I add Netflow devices, the first works, but after I add more than 10 it stops updating. The devices are not setup for netflow yet as I'm waiting for AT&T to make the changes, but removing all of them except for the one device that is setup to send netflow has restored functionality. Is there any kind of limitation on how many devices you can receive netflow from or was it that they were not setup yet and that cause a problem?
