Networking Forum powered by InfoSec Insitute

I've been searching the forums but so far can't seem to find mention of what I'm looking for, although I thought we've had discussions like this before.
I currently run Cacti and Solarwinds for all my networks.

We have several fiber networks that are basically private WAN's. We then setup site-to-site VPN with the clients to allow us to monitor and configure our equipment as needed. Many of these networks are built with redundant connections that due to contractual reasons are not always plugged in. This causes extra management of the monitoring systems if no one catches this.

I'm trying to find a free system that can monitor these networks. I want something that can support SNMP and will automatically map the network via the information given to it such as management network, SNMP, etc. or on it's own via CDP. That being said all networks are Cisco. Any ideas for something that can gather it's information automatically and show a network map with bandwidth utilization? I thought I heard MRTG or Nagios could do this but I'm not coming up with anything on my searches.

Thanks. I was looking at one called Observium but it didn't appear to have a good mapping feature. I'm downloading Zenoss right now, I'll check it out and see.

if you have ubuntu... there is a line you can add to the sources.list and then you can do apt-get install zenoss-stack

I usually use Debian. Not much different though. I tried apt-get but for some reason it doesn't work. Get this...

Code: Select all

W: Failed to fetch http://dev.zenoss.org/deb/dists/main/Release.gpg  Could not resolve 'dev.zenoss.org'
W: Failed to fetch http://dev.zenoss.org/deb/dists/main/stable/i18n/Translation-en.gz  Could not resolve 'dev.zenoss.org'
W: Failed to fetch http://dev.zenoss.org/deb/dists/main/stable/i18n/Translation-en_US.gz  Could not resolve 'dev.zenoss.org'

I'll have to figure that out first.

Huh. Never had this issue before. A fresh install of Debian and it didn't take the nameservers. Should be good to go now.

Zenoss is my first choice for free NMS. But the map feature is not going to give you link usage. You need a weather map tool for that. Such as PHP weathermap. http://www.network-weathermap.com/about

Yeah that's what I'm finding out. I use weathermap with Cacti I just hate that it requires you to not only build the map but keep it up to date too. I guess at this point I'll just do it manually.

Why don't you give it a try to "The Dude". It has many of the things you want, and some extra.

ya I bust out "The Dude" every now and then to look for link saturation

Does The Dude work with Cisco?

Works with everything that talks SNMP. So, yes, it works with Cisco too...
