Routers on a management network

[abrist]

The generic wizard will work just fine for up/down checks. When you get ready to collect bandwidth metrics, you will most likely have to delve into snmp (get your knee-high waders on and set aside a few afternoons for this).

Well I got nothing but the next two years of development to get it handled. I might as well just do it now.

I know for a typical server you need to put the snmp daemon on the server. Is there something similar to this for the router machines? (I did have cacti running for awhile until I realized this was a better option for me).

[abrist]

It sounds like these *routers* are actually *ubuntu* boxes running iptables with ip forwarding turned on. I think I missed that bit. If they really are full fledged linux boxes, you can use any of the plugins that support linux to check these boxes, like this one: http://exchange.nagios.org/directory/Pl ... nt/details

You could still go the snmp route, see the following documents for more information:

Essentially yes that's exactly what they are. I will really look over the docs you suggested before asking anymore questions. I'm sure you could keep all of you busy all day long. Thanks alot!

No problem.

One thing you will realize with Nagios is that either we, or the community have documented a huge amount of the process in configuring and tailoring both Nagios Core and XI. Also, searching the forums does wonders for finding solutions to problems, 80% or so of the issues we see are resurfaced and can be walked through to reach the same solution. But as always, we are glad to help.

So when I try to use the Generic Network Device wizard to monitor any of my VLAN's (essentially just pinging them) it isn't getting through to the VLAN even though I am giving it a specific IP Address.

Additionally, I'm monitoring a CISCO switch, through the wizard, and it picks up a single VLAN;...but skips the rest of them (there are about 20 in all).

Is there a better way to do this?

The wizard works through snmp, so you may have to use snmp-get, or better yet, snmpwalk the device to get the other vlan interface oids. Do you have an snmp/mib reference forr your cisco device? Have you tried one of the cisco plugins of the exchange? (they tend to make these types of setups easier)

You guys really are going to make me a network admin. No no and no is the answer. I will look into those and get it running in the next couple of days. I didn't set up any external plugins on my system yet...I tried but failed. Need to handled that. But I don't think our cisco device is running the vlans, they are running of the Ubuntu boxes serving as routers. Not sure if that makes a difference.

[abrist]

If the vlans are setup on the ubuntu box, you will need to target their ips with the wizard. You may need to install net-snmp packages on the ubuntu systems to do so.
