[mrtg] Re: MRTG for constantly changing networks

[Bilgrav, Martin]

Hiya,
Ont trick is to point MRTG on the IP instead of the ifindex interface.
That way, when you add or remove new interfaces, the old doesn't slide, or
cause wrongly data in graphs.

Martin

Subject: [mrtg] MRTG for constantly changing networks



I just started running MRTG and I seem to have a problem.  Right now I am
monitoring close to 200 different routers connected via Frame Relay.  Even
if I add a new sub interface to my core Cisco 7206, I'm having to do some
editing on the mrtg.cfg file so it will see my changes.  My WAN changes
almost everyday, but I don't want to have to sit and configure MRTG every
time I make a slight change on the network (increase bandwidth on a remote
circuit, change IP address, shut down or turn up an interface for a short
amount of time).  Since I am a new user it's quite possible that I am just
not using MRTG to it's full potential.  Is there a trick to getting MRTG's
config file to "update" itself as I add/remove interfaces or change
bandwidth?  Thank you.
