Nagios Support Forum

Hello everybody:
First of all, Im a spanish student in practices. The company want monitoring all the companies client.

The idea of my boss is this:

Deploy a raspberry pi 2 on the company client with a nagios core install and VPN. With the nagios recopilate all the info that need be monitoring and after send all to another nagios ( 1 central nagios that receives the information of all the nagios under VPN). The central nagios will be deploy in a VPS.
I have 2 pc for test and recreate this. I have create the typical lan nagios with a client windows and a client linux
(I have all documented on this website: jedelwey.github.io)

The problem is how can comunicate 2 nagios that are in diferents LANs, citys, etc...
And my company can't modify the network structure of the companies client.

You can see better in the file.

My Nagios versión is: Version 4.0.8 only have install nagios plugins and nrpe.

Deploy a raspberry pi 2 on the company client with a nagios core install and VPN.

When you mention that it is connected to a VPN, is this VPN connected to the same network that Nagios is on?

Yes, the raspberry pi have connect at the same LAN of the client company. For example:

Madrid: Network 10.0.0.0/24 server A: 10.0.0.30 raspberry pi 2: 10.0.0.40
Malaga: Network 172.16.0.0/24 server A: 172.16.0.30 raspberry pi 2: 172.16.0.40
Sevilla: Network 192.168.0.0/24 server A: 192.168.0.30 raspberry pi 2: 192.168.0.40

And the VPN connect:

Madrid-Sevilla
Malaga-Sevilla

The problem is how can comunicate 2 nagios that are in diferents LANs, citys, etc...
And my company can't modify the network structure of the companies client.

Madrid: Network 10.0.0.0/24 server A: 10.0.0.30 raspberry pi 2: 10.0.0.40
Malaga: Network 172.16.0.0/24 server A: 172.16.0.30 raspberry pi 2: 172.16.0.40
Sevilla: Network 192.168.0.0/24 server A: 192.168.0.30 raspberry pi 2: 192.168.0.40

And the VPN connect:

Madrid-Sevilla
Malaga-Sevilla

This is what the VPN should do, is to connect the different LANS. You will need to assign IPs to the Madrid / Sevilla VPN connection, as well as the Malaga / Sevilla connection. Push the routes, and then Nagios will be able to use the Pi as an for it's checks as logically, it will be part of both networks.

Does that make sense?
