Hello everybody!!!

I have a little request for you : do you know if some one has already written a script to create map from the database?

Thanks a lot for answering

It is true that there is not enought information ine the database. But in my case i have what i need to do this script :d
My switches and routers are configured with the name of the device which comes next to him and before him.
so i can do that.
But you may fionc lot of information in the database. Bu is not not easy to find them.

If somebody needs, i can share what i know on the databse and the tatble.

See you

So you have a list of devices (-> NODES). Each device has multiple interfaces, each in a different subnet (assume it's all layer 3 for now). The IP and netmask would tell you if an interface on device A is in the same subnet as an interface on device B. The subnet masks are not stored in the Cacti database as far as I know, unless you use a modified data query to capture that info.

The address info is stored against data sourcse, so if you can figure out which datasources are actually opposite ends of the same link, you have a way to map those interconnections to cacti datasources (for the RRD files). The OVERLIB and INFOURL can be figured out from the RRD filename (I already have a script for that part).

Finally, you need something to make some attempt at laying out the map. That could just put all the nodes in a grid and leave you to fix it in the editor, but better would be either: store pre-arranged coordinates along with the device information, or an automatic layout algorithm. I have done some work on automatic layout a while ago - it needs a lot more work.

So in fact, adding the netmask to interface.xml might allow enough info to do the job for all devices.
