Nagios XI on AWS for monitoring Internal Network

[BernyFR]

Hello everyone

I am new to Nagios and appreciate the help with a restlessness.

I already installed Nagios XI on an EC2 instance in AWS, I want to monitor all the resources or nodes of the servers that the company has in a small internal data center, database servers, desktops, etc. with this AWS Nagios EC2 instance.

Is this possible? To install Nagios XI on AWS but monitor a private internal network? How can it be done?

Thank you very much to all.

Greetings.

Though theoretically this could be done using network address translation and port forwarding, it would be extremely difficult to configure and maintain.

Alternatively, you could have a single Nagios Core/XI instance that lives on your internal network forward all of it's check results (via something like NRDP or NSCA) to a central Nagios XI instance in AWS. This would require no additional port forwarding or NAT (assuming the machine hosting the local Core/XI has internet access) since the results are pushed to Nagios XI in AWS from your network.

Again though, difficult to setup and administer. There's no specific documentation I know of for such a setup, though this covers the basics of passive checks and NRDP/NSCA:

Thank you Matt. And BernyFR, let me know if this answers your question.

Hello friends
I really appreciate your help and commitment.
This clarify my doubt, I will try to implement the solution with both servers (suggestion of mcapra).
If this does not work I will do it with only one intern server; this because I am implementing a POC.
Thank you all.
