can anybody recomend a piece of software, that could "graph" a live network scanning it via snmp. requirements are: 1. must produce a text output suitable for postproduction. graphviz is an ideal, xml - acceptable. 2. must use no external database i.e. have text config file. clean text console, suitable to run as a cronjob. 3. must be able to work in heterogenous environment.
and, the question is about producing network schematic, not about graphs like mrtg, cacti etc, etc....
Rather than SNMP probing, for larger layer3 networks try setting up a proper config archive (rancid), then build on mktop and top2dot: http://www.nanog.org/meetings/nanog26/presentations/stephen.pdf If you want to use SNMP and have good detail for layer2 networks and edge stations, take a look at http://www.netdisco.org/ Good old intermapper has been commercial for a while, does probing using several methods and makes pretty maps http://www.intermapper.com/ -- RSUC / GweepNet / Spunk / FnB / Usenix / SAGE / NewNOG
