Hi everybody,

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.

thanks a lot in advance

mrtg? www.mrtg.org

Cacti is a very useful graphing tool We have used it to graph anything we can grab via snmp.

Hope that helps.

Cacti uses MySQL, but I'm not sure if plain rrdtool does.
There is support for custom programming, so might be worth checking out.

and, the question is about producing network schematic, not about
graphs like mrtg, cacti etc, etc....

So you want a dynamic real time network discovery / topology mapping?

I think Whatsup gold tried this years ago and it could even export to Visio. But not sure lately.

This *might* do what you want. It will create the graph for you, what happens after that I don't know.

I played with it briefly but it didn't really serve a purpose for us since we derive our network layout from the OSS database.

Except for requirement #2, NetDisco would fulfill your requirements. On the
otherhand, NetDisco uses a database for topology management. For the graph
side, it creates a text file useable by graphviz.

Rather than SNMP probing, for larger layer3 networks try setting up
a proper config archive (rancid), then build on mktop and top2dot:

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/
