Internode Nodemap is a network visualization tool. Using
SNMP, it gathers a periodic snapshot of the current state of
the network. Then, under instructions from its config file, it
plots a series of "maps" of the network over the top of GIF
images in the Web server's document root, using color and
HTML CSS to indicate potential performance or reliability
problems. The maps are hierarchical "drill-down" views of
the network. The top-level map is a summary which can be
clicked on to reveal specific details; these more specific
maps can also have additional maps nested within.
