Nagios XI distributed monitoring with Nagios Core

[markf]

Hello,

I am currently evaluating Nagios XI on Linux. I have Linux Nagios Core servers already setup and running at multiple sites so I am looking at a way to centrally view them for our NOC. I looked at Fusion but I have some clients who will not allow inbound traffic from the Internet so I am now looking at using Nagios XI and passive checks instead. What is the best way to have all alerts sent passively from a Core servers to the central XI server?

I have been reading about and playing with NRDP and NRDS, which seems to be a pretty good way and uses port 80 but I don't see how to configure it so that the Core server sends all alerts for the servers that it monitors to the central server.

I have read the following guides but they do not show how to link a core server to a central XI server:

Is NSCA a better way to do this?

Thank you for your assistance.

I would highly suggest using nrdp for passive transfers between nagios systems. What seems confusing to you, I believe the Configuring inbound checks with XI should go into it, maybe not as in-depth with core as you wanted?

I have the inbound check in XI enabled and working and I am able to send from a core server but only information about the core server itself and not all of the servers and services that the core server is monitoring. I am not sure how to set it up so that all alerts from the core servers (including their monitored devices) are sent to the central XI server using NRDP. The NRDS has sample configs for individual windows and linux machines but not for a core server.

Take a look at this post, particularly scottwilkerson's first link:

Thank you. I came across this post the other night and I am giving it a try.

Sounds good. Let us know how it works out.
