How to configure NDRP clients on Nagios Core Server

Postby wizardomalex » Mon Dec 06, 2021 4:20 am

Good day all.

I am new to nagios core and I have spend a number of days trying to configure a Nagios Core Server lying in a public subnet to receive passive checks from VMs in a private subnet with a NAT gateway. The goal of the setup is to allow these internal VMs send passive checks to the Nagios Core Server on the public subnet of the same VCN.

What I have done so far

I have configured Nagios Core and NRDP servers on the Nagios Core Server and it connects successfully with hosts lying on the same subnet using NRPE.

I would really love to know how I can achieve connecting the VMs from different subnet or entirely different Cloud Platform say GCP or AWS to the Nagios Core Server which is on Oracle Platform.

I will be very grateful for any help

Hello @wiardomalex

Thanks for reaching out, to punch a hole out of your internal LAN network, you will require to forward port NRPE 5666 so that it is allowed through and mapped to your Nagios Core Server.

Simple sample:
