The openMosixmigmon is a monitor for migrations in your openMosix-cluster. It displays all your nodes as little penguins sitting in a circle.
The main penguin is the node on which openMosixmigmon runs and around this node it shows its processes also in a circle of small black squares.
-> main process-circle
If a process migrates to one of the nodes the node gets an own process-circle and the process moved from the main process-circle to the remote process-circle. Then the process is marked green and draws a line from its origin to its remote location to visualize the migration.
If you hold your mouse above a process it will show you its PID and commandline in a small tooltip-window.
