How discover host across networks

[Jacksonrb]

Hi people,
I'm really new in Nagios (3 hours of experience...). I need a help in discovery hosts across networks, I only need a keyword, name of components, etc..
My environment is a management network (10.0.0.0, for exemple) and need to monitor my server farm network (192.168.1.0). I have a server with dual network: one leg in mgmt network and other leg in server network, and this server is my "gateway" to monitor.

My doubts is: What I need install in this "gateway server" to my Nagios can monitor my servers?
I try use NRDS, but dosen't work.

Thank you so much in advantage.

Discovering and monitoring are two completely different things, and will have different methods. Which are you trying to accomplish?

Hi tmcdonald,

My objetive is monitor devices. In my mind, discovery is a process to find devices (search by ip range), and after this I can select devices to monitor.
Now I can monitor devices in the same subnet as Nagios is installed (install NSClient and add one by one in the "monitor wizard - Windows server" for exemple).
My next objetive is monitor my production server farm, that is in other subnet.

Thank you

If you can route to that network properly, you should still be able to run auto-discovery, as it uses NMAP. Have you tried manually running NMAP against that subnet? If it fails, you will have to figure out routing with your network team.

Hi slansing, thank you for your attention.

But unfortunally I have two network physically separated. We provide NOC service to customers and actually we use Microsoft SCOM, that have a component installed in a server into customer site. This component collect information from customer's devices and connect/send to my SCOM server across VPN.
If Nagios don't have this topollogy of component, I believe that I need publish my Nagios to internet with a valid IP address.
Someone have this scenario and/or have some advice, mainly about security factors in communicate client-server information over internet?


Thank you guys for your help

In this scenario we typically see users forward check results passively from one system across the wire to the main XI server. You can set this up by using this documentation:
