AgentSpotter is a multi-agent system
(MAS) profiler & visualizer, created by Dinh Doan Van Bien
for a Masters thesis at University College, Dublin. It is created on top of the NetBeans Platform, just like all these applications
. Here's one screenshot (click to enlarge it):
On the website linked above, one reads: "There are gazillions of MAS visualisation tools out there but AgentSpotter is the first to display performance data: flat profiles, call graphs, space-time diagram. You name it, we have it! So that’s doubly cool and that’s something I can boast about at the watercooler."
